Mark making tools, paper, and a steady hand

Ask anyone to name a famous English composer and they’d probably mention Ralph Vaughan Williams (1872-1958) or, more probably, Sir Edward Elgar.

Elgar was born in June 1857 in a small cottage, The Firs, in the village of Lower Broadheath, a stone’s throw west of Worcester, and 20 miles southwest from our home in Bromsgrove. The cottage (formerly the Elgar Birthplace Museum) came into the care of the National Trust in 2016 following an agreement with the Elgar Foundation. Closed for a year for some refurbishment, and the addition of a tea-room at the existing Visitor Centre among other improvements, The Firs re-opened in September 2017.

As the weather forecast for Friday (yesterday) had looked promising from earlier in the week, Steph and I made plans for a day out. But where to go? Looking through the 2018 handbook I came across The Firs (which had not featured in the 2017 handbook for obvious reasons). And with the added attraction of a two-mile circular walk in Elgar country in the vicinity, this was just what the doctor ordered!

Our visit to The Firs was beyond my expectations and unbelievably moving, even bringing me to the point of tears as I watched the 15-20 minute film about Elgar in the Visitor Centre. Throughout our visit, but especially in ‘Elgar’s Study’, I really had the feeling of being in the presence of greatness, and I can’t recall ever having had that reaction before.

Elgar’s parents William and Anne had seven children, although two died young.

William was a piano tuner, and held a warrant from Queen Adelaide (wife of William IV).

Although Elgar moved away to Worcester with his family at the age of two, he retained a life-long attachment to The Firs. At the bottom of the cottage garden (see map) there is a lovely life-size sculpture of Elgar sitting on a bench (by Jemma Pearson) gazing through a gap in the hedge towards the Malvern Hills that he loved so much. It was commissioned by the Elgar Foundation in 2007 to celebrate the 150th anniversary of Elgar’s birth.

Elgar’s daughter, Carice (born in 1890) was the inspiration, in 1935, to acquire The Firs as a memorial to her father.

Entrance to the house is by timed tickets. There’s obviously not a great deal of space inside to accommodate too many visitors at a time.

Inside the entrance porch was a small room with an iron range for heating water and cooking. Today, the National Trust has decorated the room with contemporary though not original-to-the-house items, including a piano tuner’s set of instruments.

On the ground floor, the Parlour (dedicated to Carice Elgar) has a lovely piano, possibly played by Elgar.

At the top of the stairs is a room the full width of the cottage (perhaps earlier divided into two rooms) where Elgar was born. Two other rooms and this one have displays of various musical instruments, his sporting and scientific interests, and other personal belongings such as watches.

Elgar was apparently a keen cyclist, and on one wall of the Visitor Centre there’s a mural of an exuberant cycling Elgar. We were told, although this may well only be anecdotal, that Elgar once cycled from Malvern to Wolverhampton to watch his favorite football team Wolverhampton Wanderers play. A round trip of 100 miles!

Alice and Edward Elgar in 1890

Inside the Visitor Centre, an exhibition illustrates highlights from Elgar’s life and career. He married Caroline Alice Roberts in 1889. Her parents disapproved of Elgar—a ‘jobbing musician’—and did not attend their wedding in the Brompton Oratory in London. I hadn’t realized until yesterday that Elgar was a Catholic.

Alice (who died in 1920) was his inspiration, and early on in their relationship recognized his genius. And that leads to the second point I didn’t know. Elgar received no formal musical training. It wasn’t until 1899, with the first performance of the Enigma Variations, that his growing reputation as a composer was sealed.

In ‘Elgar’s study’ there are original scores of some of his most famous works, as well as the desk at which he worked.

Alice used to prepare the paper on which Elgar composed. Apparently, specially printed paper with the staves was not available, and had to be drawn by hand using the five-pointed pen you can see in a couple of the photos above.

Land of Hope and Glory, Mother of the free‘. Famous words by Arthur C Benson put to music in Elgar’s 1901 Pomp and Circumstance March No. 1, sung here by contralto Clara Butt.

A page from the original score of ‘Land of Hope and Glory’

Who hasn’t heard Land of Hope and Glory? It’s the theme accompanying high school and university graduations around the world. Our two daughters graduated from Manila International School in the Philippines in the 1990s, and it was used then.

Another large room in the Visitor Centre, the Carice Room, is used for concerts, and where we watched the film about Elgar. There was also a lovely exhibition yesterday of watercolors by Worcestershire artist David Birtwhistle.

After a spot of lunch—we even sat outside at one of the many picnic tables—we set off on our walk, which took just over an hour. The walk begins on a public bridleway just behind The Firs, and then crosses three fields sown with oilseed rape and winter barley. By the time we reached terra firma again at Bell Lane, it felt  as though we were carrying half of Worcestershire on our muddy boots.

And at this point I must come back to Vaughan Williams for a moment, because as we were walking across the barley field, and looking back towards Worcester Cathedral to the east, a skylark rose into the air in front of us, singing lustily throughout its ascent and as it glided slowly back to earth.

What a wonderful sight and sound, reminding me instantly of Vaughan Williams’s The Lark Ascending premiered in 1920, although originally written for violin and piano in 1914.

The staff and volunteers at The Firs were outstanding, and their friendliness and readiness to engage with us added to the enjoyment of our visit. As I said at the outset, we didn’t have any particular expectations when deciding to visit Elgar’s birthplace. I came away deeply affected by what I saw, heard, and learned, and I’m sure that the emotion will stay with me for many days to come. And, coincidentally, as I am finishing writing this post, while listening to Classic FM, Elgar’s Cello Concerto in E minor, Op. 85 has just been featured.

 

 

 

 

 

Fashion, so said Louis XIV, is the mirror of history

Amber Butchart (photo by Jo Duck – used with permission)

Just when you least expect it, a real gem of a television series comes along. You’re gathered in. Then you’re hooked!

And that was our experience with fashion historian Amber Butchart’s six part series, A Stitch In Time, recently screened on BBC4.

This is what Amber has to say about the series on her blog: Fusing biography, art and the history of fashion, throughout A Stitch in Time I get to explore the lives of historical figures through the clothes they wore, while key garments are recreated using the original techniques.

She peers into the mirror and helps us to interpret the costume clues held within Van Eyck’s mysterious Arnolfini portrait, the role of hand-me-downs among 18th century workers, the impact of cotton on British life, a flamboyant armorial piece which sits at odds with the allegedly brutal nature of its wearer and the impact a scandalously informal gown would have on an already unpopular queen.

What an eye-opener A Stitch in Time has been! And from what I’ve seen in various media, we are not alone in being enthralled by the series.

My wife Steph and I enjoy watching almost any history-related program, so tuned into the first episode on 3 January almost by default. We had no idea what to expect, and we’d never heard of Amber Butchart (herself a fashion icon) even though (as I’ve now discovered) she has broadcast regularly over the past four or five years on BBC radio.

To recreate the items of clothing, Amber relied on the talents and experience of historical costumier Ninya Mikhaila  and her team, Harriet Waterhouse and Hannah Marples. It was amazing to see how every item of clothing was hand stitched. Not a sewing machine is sight, nor an electric iron.

L to R: Harriet, Ninya, Amber, and Hannah

In each program Amber talked about a particular painting—and a tomb effigy in one program—and what each tells us about the person(s) portrayed, how their clothing speaks to us about their social status, and the society in which they lived. And then she enjoyed modeling each of the recreated costumes.

She also delved into other background issues that are part of the story, none perhaps more emotive than that of Dido Belle, born in 1761 the natural (i.e. illegitimate) daughter of Sir John Lindsay and a slave, who moved in the highest circles of English aristocracy since her great uncle was Lord Mansfield, the Lord Chief Justice. I was already familiar with her story having read the 2014 book that same year by Paula Byrne.

Choosing the topics
I asked Amber how she came to choose the six subjects for the series. She replied: I wanted to show a real range of clothing from history—not just womenswear and royalty. I also wanted to touch on stories that are harder to uncover, to show the difficulties that can be part of the process when looking at marginalised histories. So I chose the artworks for a mixture of these reasons—plus some which are more well known within fashion history, such as Marie Antoinette and Charles II.

Charles was the subject of the first program (depicted receiving a pineapple from his head gardener, in a painting from around 1667, now part of the Royal Collection Trust, © Her Majesty Queen Elizabeth II) and “how he used fashion as propaganda with an outfit that foreshadowed the three piece suit”. From what appeared a rather drab suit of clothes in the painting, the completed reconstruction was extremely elegant, with its shot silk lining and black silk ‘bows’ on the trousers, shoulder and sleeves. The other fashion statement is the fantastic number of handmade buttons and their corresponding button-holes.The second program considered the famous Arnolfini portrait by Van Eyck from 1434, that hangs today in the National Gallery.

Once thought to portray a pregnant Mrs Arnolfini, wife of a wealthy merchant, this is no longer believed to be the case. She’s just holding up the rather large amount of cloth that went into making her dress—just because she could, a sign of the family’s wealth. The resulting recreation was stunning, and it was also interesting to watch how the green dye was made. Not for those of a weak olfactory constitution!

The ‘common man’ was the subject of the third program, depicted in a full-size portrait at Broughton Castle in Oxfordshire. Portraits of working men are uncommon. Just take a visit to any National Trust property, as Steph and I do all year round, and there are a thousand and one portraits of members of the aristocracy in all their finery. Such statements of power and fashion!

But The Hedge Cutter at Broughton shows a working man wearing a hand-me-down leather coat, evidently worn by several  generations and generously patched. It’s dark and stained, tattered in places.

The coat expertly recreated by Ninya and her team from soft, pale leather was a delight to behold. Even more compelling were the sewing techniques they had to employ to join the expensive pieces of leather together.

The story of Dido Belle in Program 4, was particularly interesting. In the painting of Dido (with Lady Elizabeth Murray), on display at Scone Palace in Scotland, not all of her dress can be seen, so Ninya and her team had to interpret how it might have been made.

Calling upon all their knowledge and experience, they recreated a dress that they believe was close to the original. Ninya confirmed to me that Dido’s clothes were the biggest challenge to research, mainly because so much of them are obscured in the painting, and because very little survives in the way of informal dress. Loose, voluminous garments made from expensive silk are prime targets for being made over, cut and reused. As we said in the programme, we were very happy with the results, but there were definitely several possible answers for how this gown was actually cut and constructed!

The Black Prince, son of King Edward III and father of King Richard II, is buried in Canterbury Cathedral, and Amber took us to look at the prince’s gilt-bronze tomb effigy, which shows the item of clothing that was the focus of this episode. The prince is wearing a jupon, a close-fitting tunic worn over a suit of armor and bearing heraldic arms. Warriors wore such an item of clothing in battle so they could be recognized and serve as a rallying point for their troops.

What was particularly interesting about this program (5) is that the prince’s original jupon still exists although no longer on display. After 600 years it’s just too fragile. But after his death in 1376, the jupon was hung above the prince’s tomb and remained there for centuries. Now stored carefully away in a box at the cathedral, the jupon no longer displays its vibrant colors, and although there was perhaps less interpretation needed to reconstruct it, there were still some challenges. The principal one was how to sew the cotton protective wadding between the layers of linen as a backing and the red and blue velvet of the outer layer.

Nevertheless, the completed garment was the most exuberant of the series. As Ninya told me: I loved working on the Black Prince’s jupon. It was an incredibly time-consuming process but it was so rewarding seeing it emerge in all its brightly coloured, gold-embellished glory!

Apparently the gold embroidery alone took 900 hours to complete, stitched on to a linen backing, cut out, and then sewn on to the jupon. Stunning!

In the final programme, Amber explained the court reaction to the most unroyal-like muslin dress (chemise de la reine) worn by the unpopular Austrian-born Queen Marie Antoinette, wife of Louis XVI, in an infamous portrait painted by Louise Élisabeth Vigée Le Brun in 1783. Such was the uproar, that the artist had to paint another portrait in a more appropriate dress worthy of a French queen. Muslin was used for undergarments, not for royal portraits. Vigée Le Brun painted more than 30 portraits of Marie Antoinette.

The recreation was an elegant, free-flowing gown, but not (to our modern eyes) the scandalous display for which Marie Antoinette was censured. She would have worn this type of dress in informal settings such as her retreat in the grounds of the Palace of Versailles, the Petit Trianon, surrounded by intimates. Underneath the dress Marie Antoinette would have worn stays, and these were also part of the recreation. Ninya told me: . . . the silk damask stays that Harriet made for Marie Antoinette were ridiculously beautiful. There was an elegant sash at the waist, made by Hannah.

Even though the dress looks simple in style, it would nevertheless have been costly to make in the 18th century, as was demonstrated in its reconstruction. Ninya also gave a useful tip to all budding seamstresses on how to make a level hem. Tip of the series!

Perspectives
On reflection, I found the story of Dido Belle the most compelling. And while her dress appeared the most simple among the six, it was, as Ninya told me, a challenge for her team.

But as I think back on the last program and the beautiful dress that was worn by Marie Antoinette, I have to say that was my favorite. Elegant in its ‘simplicity’.

I asked Amber which costume she found the most challenging. This is what she told me: The most challenging to research in many ways was Dido Belle, and also the Hedge Cutter. Researching working dress can be difficult as it doesn’t tend to be kept in museums and wasn’t seriously written about until relatively recently. Dido has a really compelling story, and the transatlantic slave trade played a huge part in our history but is often overlooked. It runs like a thread through fashion history as it relates to cotton, and so I felt it needed to be addressed.

But what was her favorite costume? Having discovered online (from an interview she once gave) that green is apparently her favorite color, I expected her to choose the Arnolfini dress. But no!

In terms of aesthetic, I love the Charles II suit and would absolutely wear it, she replied (in the photo above it does really look elegant on her). In terms of uniqueness of experience, she continued, and historical revelation, it would be the Black Prince’s jupon. Such an incredible experience to literally walk in his shoes, and so far from the clothing that we’re used to today. Experimental archaeology at its best!

So there you have it.

I don’t think I’ll look at a portrait again in quite the same way during one of my many National Trust visits. This series has certainly opened my eyes to another aspect of social history that had, until now, passed me by.

If I have one criticism of the series, it would be this. Each program was short by about 15 minutes, that would have allowed just a little more time to explore the background story, and to focus in on some more detail of the actual techniques for making the costumes. BBC producers take note!

So, I hope that the BBC will commission another series, and allocate sufficient air time to do justice to this fascinating subject. Amber Butchart’s A Stitch in Time has been a joy to watch. This is why we willingly pay the TV licence fee.

 

 

 

 

 

 

 

 

The Birmingham Class of ’71: plant genetic resources pioneers

Pioneers. That’s what we were. Or, at least, that’s what we thought we were.

Five individuals arriving at The University of Birmingham’s Department of Botany in September 1970 to study on the one-year MSc degree course Conservation and Utilization of Plant Genetic Resources (CUPGR).

Professor Jack Hawkes was the Course Leader, supported by Dr Trevor Williams (as Course Tutor) [1].

Professor Jack Hawkes (L) and Dr Trevor Williams (R)

The MSc course had its first intake (of four students from Canada, Brazil, and the UK) in September 1969. Twenty years later (which was celebrated at the time), hundreds of students had received training in genetic conservation at Birmingham. The course would continue to flourish for a further decade or so, but by the early 2000s there was less demand, limited financial resources to support students, and many of the staff at the university who were the lynch-pins of teaching on the course had moved on or retired.

However, the course had made its impact. There is no doubt of that. Birmingham genetic resources graduates were working all around the world, leading collection and conservation efforts at national levels and, in many cases, helping their countries—and the world—to set policy for the conservation and use of plant genetic resources for food and agriculture (PGRFA). At the FAO conference on PGRFA held in Leipzig, Germany in 1996, for example, about 50 of the national delegations were led by, or had members, who had received training at Birmingham.

The Class of ’71
So, in September 1970, who comprised the second CUPGR cohort? We came from five countries:

  • Felix Taborda-Romero from Venezuela
  • Altaf-ur-Rehman Rao from Pakistan
  • Ayla Sencer from Turkey
  • Folu Dania-Ogbe from Nigeria
  • Mike Jackson (me!) from the UK

Having just graduated a couple of months earlier from the University of Southampton with a BSc degree in Botany and Geography, I was the youngest of the group, just approaching my 22nd birthday. Folu was almost four years my senior, and Ayla was perhaps in her late twenties or early thirties, but I’m not sure. Altaf was 34, and Felix the ‘elder’ of the class, at 38.

I guess Ayla was the only one with a specific genetic resources background, coming to Birmingham from an agricultural research institute near Izmir, and having already been involved with conservation work. Felix and Altaf were both academics. As recent graduates, Folu and I were just starting to think about a career in this new field of plant genetic resources. We wouldn’t be disappointed!

Studying alongside mature students who were not only older than my eldest brother (nine years my senior), but who had taken a year out from their jobs to study for a higher degree, was a novel experience for me. There was also a language barrier, to some extent. Felix probably had the weakest English skills; Ayla had already made some good progress before arriving in Birmingham but she struggled with some aspects of the language. Both Altaf and Folu spoke English fluently as a second language.

We occupied a small laboratory on the north corridor, first floor of the School of Biological Sciences building, just a couple of doors down from where Jack, as Mason Professor of Botany and Head of Department, had his office, and just across from Trevor’s office. In 1981, when I returned to Birmingham as Lecturer in Plant Biology, that same room became my research laboratory for six or seven years.

Folu and myself had desk space on one side of the lab, and the others on the other side. We spent a lot of time huddled together in that room. In order to save us time hunting for literature in the university library, we had access to a comprehensive collection of photocopies of many, if not most, of the scientific papers on the prodigious reading lists given to us.

Richard Lester

We had a heavy schedule of lectures, in crop evolution, taxonomic methods, economic botany (from Dr Richard Lester), population genetics and statistics (from staff of the Department of Genetics), computer programming and data management (in its infancy then), germplasm collection, and conservation, among others. At the end of the course I felt that the lecture load during that one year was equivalent to my three-year undergraduate degree course. We also had practical classes, especially in crop diversity and taxonomy, and at the end of the teaching year in May, we had to sit four written exam papers, each lasting three hours.

There were also guest lectures from the likes of experts like Erna Bennett (from FAO) and Jack Harlan from the University of Illinois.

We also had to choose a short research project, mostly carried out during the summer months through the end of August, and written up and presented for examination in September. While the bulk of the work was carried out following the exams, I think all of us had started on some aspects much earlier in the academic year. In my case, for example, I had chosen a topic on lentil evolution by November 1970, and began to assemble a collection of seeds of different varieties. These were planted (under cloches) in the field by the end of March 1971, so that they were flowering by June. I also made chromosome counts on each accession in my spare time from November onwards, on which my very first scientific paper was based.

At the end of the course, all our work, exams and dissertation, was assessed by an external examiner (a system that is commonly used among universities in the UK). The examiner was Professor Norman Simmonds, Director of the Scottish Plant Breeding Station (SPBS) just south of Edinburgh [2]. He made his scientific reputation working on bananas and potatoes, and published several books including an excellent text on crop evolution [3].

Then and now
So how did we all end up in Birmingham, and what happened after graduation?

Felix received his first degree in genetics (Doutor em Agronomia) in 1955 from the Escola Superior de Agricultura Luiz de Queiroz, Universidade de São Paulo in Brazil. He was a contemporary of Almiro Blumenschein, who went on to collaborate with geneticist and Nobel Laureate Barbara McLintock on the maizes of South America, and head the Brazilian agricultural research institute EMBRAPA (which is the parent organization for the Brazilian national genebank CENARGEN).

Returning to Venezuela, Felix was involved (from 1956-1961) with a national project to breed the first Venezuelan hybrid corns and to organize commercial seed production while also looking after a collection of local varieties and races of corn.

In 1961 he started to work in the Facultad de Agronomía at the Universidad del Zulia, now one of the largest and most important universities in Venezuela. It seems he found out about the Birmingham course in 1969 through contact with Dr Jorge León, a Costarrican botanist working for IICA who had also been worked at FAO in genetic resources, and was a contemporary of Jack Hawkes in the 1960s genetic resources movement. León is second from right, standing, in the photo below. But Felix had also been inspired towards plant genetic resources by the book Plants, Man and Life by American geneticist Edgar Anderson.

Felix self-financed his studies at Birmingham, having taken a sabbatical leave from his university, and arriving in Birmingham by the middle of August. In December 1970, Felix returned briefly to Venezuela to bring his young wife Laura and his newly-born son Leonardo to Birmingham. They took up residence in a house owned by Jack Hawkes in Harborne, a suburb close to the university.

His dissertation, on the effect on growth of supra-optimal temperatures on a local Venezuelan sorghum variety, was supervised by plant physiologist Digby Idle. Having been awarded his MSc (the degree was conferred in December 1971), Felix returned to his university in Maracaibo, and continued his work in sorghum breeding. He was one of the pioneers to introduce grain sorghums in Venezuela, and continued working at the university up until about five years ago when, due to the deteriorating economic and social situation in his native country, Felix and Laura (who has an MSc degree from Vanderbilt University) decided to move to Florida and enjoy their retirement there. His three sons and six grandchildren had already left Venezuela.

Felix and I made contact with each other through Facebook, and it has been wonderful to catch up with him after almost five decades, and to know that since his Birmingham days he has enjoyed a fruitful career in academia and agricultural research, and remains as enthusiastic today, in his mid-eighties, as he was when I first knew him in September 1970.

Altaf was born in Faisalabad in December 1936, and when he came to Birmingham in 1970 he was already Assistant Professor in the Department of Botany at the University of Agriculture in Faisalabad. He had received his BSc (Agric.) degree from that university in 1957, followed by an MSc (Agric.) in 1962.

I cannot remember the topic of his dissertation nor who supervised it, perhaps Richard Lester. After graduation he moved to Bangor University to complete a PhD in 1974 on the genetic variation and distribution of Himalayan wheats and barleys, under the supervision of Professor John Witcombe (from whom I obtained the various photos of Altaf). In 1974 he joined a joint Bangor University-Lyallpur University to collect wheats and barley in northern Pakistan.

He continued his teaching at Faisalabad until 1996 when he retired as Professor of Botany. But he wasn’t finished. He joined the Cholistan Institute of Desert Studies at Islamia Universty and was director from 1998 to 2000. Sadly, in December 2000, just four days after his 64th birthday, Altaf passed away, leaving a wife, two daughters and four sons. Remembered for his devotion to plant genetic resources and desert ecology, you can read his obituary here.

Genetic resources conservation in Turkey received a major boost in the mid-1960s when an agreement was signed between the Government of Turkey and the United Nations Special Fund to establish a ‘Crop Research and Introduction Centre‘ at Menemen, Izmir. The Regional Agricultural Research Institute (ARARI, now the Aegean Agricultural Research Institute) became the location for this project, and Ayla was one of the first scientists to be involved.

Ayla came to Birmingham with a clear focus on what she wanted to achieve. She saw the MSc course as the first step to completing her PhD, and even arrived in Birmingham with samples of seeds for her research. During the course she completed a dissertation (with Jack Hawkes) on the origin of rye (Secale cereale), and she continued this project for a further two years or so for her PhD. I don’t recall whether she had the MSc conferred or not. In those days, it was not unusual for someone to convert an MSc course into the first year of a doctoral program; I’m pretty sure this is what Ayla did.

Completing her PhD in 1973 or 1974, Ayla continued to work with the Turkish genetic resources program until 1981 when she accepted a position at the International Maize and Wheat and Improvement Center (CIMMYT) near Mexico City, as the first curator of the center’s wheat collection.

I believe Ayla stayed at CIMMYT until about 1990 or so, and then returned to Turkey. I know that she has retired with her daughter to a small coastal town southwest from Izmir, but I’ve been unable to make contact with her directly. The photo below was sent to me by Dr Tom Payne who is the current curator of CIMMYT’s wheat collection. He had dinner with Ayla a couple of years ago during one of his visits to Turkey.

Folu married shortly before traveling to Birmingham. Her husband had enrolled for a PhD at University College London. He had seen a small poster about the MSc course at Birmingham on a notice board at the University of Ibadan, Nigeria where Folu had completed her BSc in Botany. She applied successfully for financial support from the Mid-Western Nigeria Government to attend the MSc course, and subsequently her PhD studies.

Dr Dennis Wilkins

Before coming to Birmingham, Folu had not worked in genetic resources, but had a flair for genetics. Like me, she hoped that the course would be a launch pad for an interesting career. Her MSc dissertation—on floating rice—was supervised Dr Dennis Wilkins, an ecophysiologist. In the late 70s and early 80s, Dennis supervised the PhD of World Food Prize Laureate Monty Jones, who is now the Minister of Agriculture, Forestry and Food Security in Sierra Leone.

After completing her MSc, Folu began a PhD under the supervision of Trevor Williams on the taxonomy of West African rice, which she completed in 1974. To successfully grow her rice varieties, half of one glasshouse at the department’s garden at Winterbourne was successfully converted to a rice paddy.

In this photo, taken during her PhD studies, Folu’s mother (who passed away in January 2018) visited her in Birmingham. Folu can’t remember the three persons between her and her mother, but on the far left is Dr Rena Martins Farias from Brazil, who was one of the first cohort of MSc students in 1969.

Folu also had the opportunity of joining a germplasm collecting mission to Turkey during 1972. In this photo, Folu (on the right) and Ayla (on the left) are collecting wheat landrace varieties.

Returning to Nigeria, Folu joined the Department of Plant Biology at the University of Benin, Benin City until 2010, when she retired. She taught a range of courses related to the conservation and use of plant genetic resources, and conducted research on the taxonomy of African crop plants, characterization of indigenous crops from West Africa, and the ethnobotany of useful indigenous African plants. She counts among her most important contributions to genetic resources the training courses she helped deliver, and the research linkages she promoted among various bodies in Nigeria. She has published extensively.

After retirement from the University of Benin, she was seconded to the new Samuel Adegboyega University at Ogwa in Edo State, where she is Professor and Dean of the College of Basic and Applied Sciences. She has three children and five grandchildren.

As for myself, I was the only member of our class to be interviewed for a place on the MSc course, in February 1970. I’d heard about it from genetics lecturer at Southampton, Dr Joe Smartt, who stopped me in the corridor one day and gave me a pamphlet about the course, mentioning that he thought this would be right up my street. He wasn’t wrong!

However, my attendance was not confirmed until late August, because Jack Hawkes was unable to secure any financial support for me until then.

Trevor Williams supervised my dissertation on the origin of lentil (Lens culinaris), but as early as February 1971, Jack Hawkes had told me about an opportunity to work in Peru for a year after I’d completed the course, looking after a germplasm collection of native potato varieties at the newly-established International Potato Center (CIP) in Lima. In October 1971 I began a PhD (under Jack’s supervision) on the relationships between diploid and tetraploid potatoes (which I successfully defended in October 1975), and joined CIP in January 1973. Continuing with my thesis research, I also made several potato collecting missions in different regions of Peru.

From 1976-1981 I continued with CIP as its regional research leader in Central America, based in Costa Rica, working on disease resistance and potato production. I spent a decade back at The University of Birmingham from April 1981, mainly teaching on the genetic resources MSc course, carrying out research on potatoes and legumes, and supervising PhD students.

In 1991, I joined the International Rice Research Institute (IRRI) at Los Baños in the Philippines as the first head of the Genetic Resources Center, looking after the International Rice Genebank, and managing a major project to collect and conserve rice genetic resources worldwide. In 2001, I gave up research, left the genebank, and joined IRRI’s senior management team as Director for Program Planning and Communications, until 2010 when I retired.

But I’ve not rested on my laurels. Since retirement, I’ve organized two international rice science conferences for IRRI in Vietnam and Thailand, co-edited a second book on genetic resources and climate change, and led a review of the CGIAR’s genebank program.

My wife Steph is a genetic resources graduate from Birmingham, in 1972, and she joined me at CIP in July 1973 after leaving her position at the Scottish Plant Breeding Station where she helped to curate the Commonwealth Potato Collection (CPC).

We have two daughters, Hannah and Philippa (both PhD psychologists), and four grandchildren.

Sitting (L to R): Callum, Hannah, Zoe, Mike, Steph, Elvis, Felix, and Philippa. Standing: Michael (L) and Andi (R).

Looking back at the past five decades, I think I can speak for all of us that we had successful careers in various aspects of the conservation and use of plant genetic resources, repaying the investments supporting us to study at Birmingham all those years ago. What a journey it has been!

Taking in the central sierra . . .

September 1973. One of our first road trips in Peru, a circular route taking in Pisco on the coast south of Lima, before heading up into the Andes to Ayacucho, before heading north to Huancayo, and then back down to Lima. I’m sure the trip today is much easier than 43 or 44 years ago.

On the first day we drove south just as far as Pisco, spending one night there before attempting the next stage over the mountains to Ayacucho. Apart from the coastal Panamerican Highway and the road from Huancayo back to Lima, which were paved, the others were dirt roads in various states of repair. At the highest point on the road between Pisco and Ayacucho, we encountered one particularly stretch of muddy road that I thought we just might halt our trip. But with some expeditious maneuvering, I managed to extricate us from mud almost up to the axles.

The road up from Pisco.

If I remember correctly, the road dropping down to Ayacucho seemed to last forever, a long and relatively gentle decline. It was above Ayacucho where I took this photo, one of my favorites in all I took during our three years in Peru.

Staying at the turista hotel just off the main square, we spent a couple of nights in Ayacucho, and enjoyed its pleasant climate, lying as it does in a wide, fertile valley, just below 2800 m above sea level.

North from Ayacucho the road crosses a wide, high altitude plain, dotted everywhere with cacti. Further north, it follows the steep-sided valley of the Mantaro River, and is carved into the side of the mountain. Maybe it has been widened today, but back in the day, it was so narrow that traffic flow was one-way only on alternate days. This had to be factored into our road trip planning of course.

It was an easy day’s drive between Ayacucho and Huancayo, and we spent a couple of nights there. As the International Potato Center (CIP) had its highland experiment station close to Huancayo in the Mantaro Valley, and Steph and I would travel there almost every week during the potato growing season between November and May, we took the opportunity of passing through Huancayo to check a few work-related items before passing through on our way back down to Lima along that familiar road that crosses Ticlio at almost 5000m.

This trip must have lasted about seven days, maybe eight. With the others we made, as well as the various potato collecting trips that I made as part of my work, we were fortunate to explore many parts of this beautiful country.

Here is a list of those trips:

 

Breathing life into history

As regular readers of this blog will know, one of my hobbies is history (and archeology to some extent). I’ve often wondered whether I should have read history at university instead of botany. And, when I retired almost eight years ago, I did ponder taking a history degree course at the Open University. However, having decided that retirement meant I no longer had to meet deadlines any more, the allure of studying again soon faded.

Nevertheless, much of my reading focuses on history, and I’ve built up a sizeable library (mostly paperbacks) covering all periods and disciplines (social, economic, cultural, etc.). When we lived overseas in the Philippines I would take back half a suitcase of books after each annual home-leave in the UK. Near where my elder daughter lives in St Paul, Minnesota there is an excellent book store where I’ve been able to pick up a whole range of texts, many about the American Civil War, that I’ve never seen on sale over this side of the Atlantic. There are several university colleges near Half Price Books on Ford Parkway, where students divest themselves of course books each year—to my great advantage.

Here in the UK we are also fortunate that BBC2, BBC4 and Channel 4 regularly broadcast history programs of high quality, and others on archaeology, that provide interesting perspectives on how cultures and societies evolved. Steph and I have been enjoying many of these since we returned to the UK in 2010.

I guess my own fascination with history and archaeology on TV began with Sir Kenneth Clark’s Civilisation, a thirteen part documentary series, first broadcast on BBC2 in 1969 about the history of Western art, architecture and philosophy since the Dark Ages. It was apparently the first series commissioned specifically for colour television in the UK (by Sir David Attenborough, then Controller of BBC2). I didn’t actually see the series then; I was too busy being an undergraduate. We acquired the DVD in 2005.

Jacob Bronowski’s The Ascent of Man, broadcast in 1973 (and which we also viewed years later on DVD), was a highly-acclaimed personal view about the development of human society through its understanding of science.

Simon Schama’s A History of Britain (broadcast from September 2000, over 15 hour-long programs in three series until June 2002) was his personal view of different periods of British (actually, mainly English) history and its events. Once again, we caught up on DVD.

And during this period of working overseas, we enjoyed (on DVD) an impressive list of programs by Michael Wood, in a broadcasting career that began in 1979. He has had several series since we returned to the UK.

David Starkey is a hardy perennial who focuses on the Tudors. Despite several controversies that have surrounded him, he still appears quite regularly.

There is quite a long list of presenters (see below) whose programs we have enjoyed since 2010, covering a wide range of topics and periods. Just this past few weeks we’ve enjoyed a three-part series by Helen Castor about England’s first queen, Jane (great granddaughter of Henry VII), whose reign lasted just nine days in July 1553.

Art historian Andrew Graham-Dixon is the ‘flavor of the month’ right now. A two part series, Rome Unpacked, co-presented with chef Giorgio Locatelli about the cultural history of Rome and its cuisine concluded last week. For some reason we didn’t watch the three series of Italy Unpacked broadcast between 2013 and 2015. He’s just started a four part series about the Royal Collection on BBC4, and next week he has a one-off program on BBC2 about the theft of two paintings by Van Gogh from a museum in Amsterdam in 2002. He’s certainly one of the most engaging presenters currently on TV.

But there are two presenters who are new to me with series showing right now on BBC2 and BBC4, respectively.

David Olusoga is a British Nigerian historian, writer and broadcaster who I’d never heard of until his four part series A House Through Time began three weeks ago. It tells the social history of Liverpool through the lives of families who occupied a single house, from when it was built about 200 years ago until the present day.

62 Falkner Street (at one time, number 58) is a four storey terraced house in what was once a fashionable neighborhood, in the Georgian Quarter east of the city center, but within easy striking distance of the docks that were the basis of the city’s prosperity for so many decades.

It has been painstakingly researched. There must be a large team of researchers behind the scenes digging into the census records and other documents published in Liverpool that have provided insights into the business and economic history of the city. It’s a very engaging way to tell the social history of this important port city in England’s northwest, that climbed to the pinnacle of economic prosperity in the 19th century, and fell to the depths of economic decline in the late 20th.

Combining the history of art and fashion, A Stitch in Time (a six part series on BBC4) is presented by TV newcomer Amber Butchart, who has published several books and appears regularly apparently on BBC radio.

Amber is certainly a breath of fresh air, with her flamboyant fashion style, bright red hair, and piercingly blue eyes. Her range of clothes certainly needs a personality like Amber’s to carry off successfully. Elegant!

Working with historical costumier Ninya Mikhaila and her team, Amber fuses biography, art, and the history of fashion, and explores the lives of historical figures through the clothes they wore.

In the first program, she looked at the fashion of Charles II’s restoration, and in the second the green gown worn by the lady in the 1434 Arnolfini portrait, painted by Jan van Eyck. The third program was unusual in that the portrait was of a working man, a hedge-cutter, wearing a hand-me-down leather coat.

In each program Amber talks about the social status and lives of the subjects that we can deduce from each painting, while Ninya and her team recreate a costume just from their view of the painting and their detailed understanding of how clothes were made in the past. The Arnolfini recreation was outstanding.

From the outset I wouldn’t have imagined that a series along these lines would grab my attention. I guess we watched the first episode because there was nothing else worth watching across the channels. But then we were hooked, and I hope that the BBC will commission Amber to undertake other projects in the future.

Wishing I was in Cuzco . . .

The 10th World Potato Congress takes place in the southern Peruvian city of Cuzco at the end of May this year. I wish I was going.

It would be a great opportunity to renew my links with potato research, and revisiting one of Peru’s most iconic cities would be a joy.

I like this quotation from the Congress website: Potatoes are the foundation of Andean society. It shaped cultures and gave birth to empires. As the world population explodes and climate change places increased demands on the world’s farmers, this diverse and hearty tuber will play an instrumental role in feeding a hungry planet.

Cuzco lies at the heart of the Andean potato culture. The region around Cuzco, south to Lake Titicaca and into northern Bolivia is where most diversity in potatoes and their wild species relatives has been documented. When I worked for the International Potato Center (CIP) in Peru during the early 1970s I had several opportunities of looking for potatoes on the Peruvian side of the border, and made three (possibly four) visits to Cuzco. I see from a quick scrutiny of the street map of Cuzco on Google maps that the city has changed a great deal during the intervening years. That’s hardly surprising, including many fast food outlets dotted around the city. The golden M get everywhere! Also there are many more hotels (some of the highest luxury) in the central part of the city than I encountered 45 years ago.

At Machu Picchu in January 1973

I visited Cuzco for the first time within two weeks of arriving in Peru in January 1973. The participants of a potato germplasm workshop (that I described just a few days ago) spent a few days in Cuzco, and I had the opportunity of taking in some of the incredible sights that the area has to offer, such as Machu Picchu and the fortress of Sacsayhuamán on the hillside outside the city.

Steph and I were married in Lima in October 1973, but we delayed our honeymoon until December. And where could there be a more romantic destination than Cuzco, taking in a trip to Machu Picchu (where we stayed overnight at the turista hotel right beside the ruins), Sacsayhuamán, the Sacred Valley, and the Sunday market at Pisac.

In the early 70s, the Peruvian airline Faucett flew Boeing 727s into Cuzco. In January 1973 I’d only ever flown three times: in 1966 to the Outer Hebrides in Scotland on a BEA Viscount turboprop; from London to Istanbul on Turkish Airlines to attend a scientific meeting in Izmir; and the intercontinental flight from London to Lima with BOAC.

Flying into Cuzco was (is) quite an experience. There’s only one way in, and out! It is quite awesome (if not a little unnerving) dropping through the cloud cover, knowing that some of the highest mountains in the world are just below, then seeing the landscape open as you emerge from the clouds, banking hard to the left and follow the valley, landing at Cuzco from the east.

The city has now expanded eastwards beyond the airport, but in 1973 it was more or less at the city limits. The main part of the city lies at the western end of the runway, and hills rise quite steeply just beyond, thus the single direction for landing and the reverse for take-off. Maybe with new, and more highly powered aircraft, it’s now possible to take off to the west. Those attending the World Potato Congress should have a delightful trip from the coast. By the end of May the dry season should be well-established, and the skies clear.

So, what is so special about Cuzco? It’s a city steeped in history, with Spanish colonial buildings blending into, and even constructed on top of the Inca architecture. That architecture leaves one full of wonder, trying to imagine how the stones were brought to the various sites, and sculpted to fit so snugly. Perhaps the best example is the twelve-sided (or angled) stone in the street named Hatun Rumiyoc (a couple of blocks east of the Plaza de Armas). This is taken to an even greater level at Sacsayhuamán, with an enormous eleven-sided stone.

My first impressions of Cuzco were the orange-tiled roofs of most buildings in the city.

All streets eventually lead to the main square, the Plaza de Armas in the city center, dominated on its eastern side by the Cathedral Basilica of the Assumption of the Virgin, and on its southern side by the late 16th century Templo de la Compañía de Jesús (a Jesuit church).

One of the finest examples of the Inca-Colonial mixed architecture is the Coricancha temple upon which was constructed the Convent of Santo Domingo. The Incan stonework is exquisite (although showing some earthquake damage), and inside 16th/17 century paintings have survived for centuries.

Another aspect of Cuzco’s architectural heritage that caught our attention were the balconies adorning many (if not most) buildings on every street, at least towards the city center.

In the early 1970s steam locomotives were still in operation around Cuzco and, being somewhat of a steam buff, I had to take the opportunity of wandering around the locomotive shed. During our trip to Machu Picchu, our tourist diesel-powered train actually crossed with another pulled by a steam locomotive.

Outside the city, to the north lies the Inca fortress citadel of Sacsayhuamán, the park covering an area of more than 3000 hectares. Steph and I spent a morning exploring the fortress, viewing it from many different angles, and pondering just how a workforce (probably slave labour) came to construct this impressive site, with its huge stones so closely sculpted against each other that it’s impossible to insert the blade of a knife.

Among the most commonly visited locations by many tourists is the small town of Pisac, some 35 km from northeast of Cuzco at the head of the Sacred Valley, where a vibrant market is held each Sunday. We took a taxi there, and joined quite a small group of other tourists to wander around, bargain for various items (including an alpaca skin rug that we still had until just a couple of years ago). This is not a tourist market, however—or at least it wasn’t in December 1973 when we visited. As you can see in the slideshow below, it was very much a place and occasion frequented by people coming from the surrounding communities to sell their produce, and meet up with family and friends. Whenever I look at these photographs I always feel quite sad, as it’s likely that many who appear have since passed away.

It’s no wonder that Cuzco and surrounding areas have been afforded UNESCO World Heritage status (as so many other treasures in this wonderful country). So, as I think about the opportunities that potato scientists from all around the world will enjoy when they visit Cuzco at the end of May, I can’t help but feel a tinge of envy. However, they’d better take advantage of the odd cup of coca tea, or maté de coca, if offered. An infusion of coca leaves (yes, that coca!), it really does help mitigate the effects of high altitude and the onset of so-called ‘altitude sickness’.

 

How long is a piece of string?

Just three decades after Spanish conquistador Francisco Pizarro first encountered the potato in the high Andes of Peru in 1532, the potato was already being grown in the Canary Islands. And it found its way to mainland Europe via the Canaries shortly afterwards [1].

The first known published illustration of the potato in Gerard’s Herball of 1597.

The potato was described by English herbalist John Gerard in his Herball published in 1597. In a revised version, published in 1633 over 20 years after his death, there is another beautiful woodcut of the potato, referred to Battata Virginiana or Virginian potatoes.

Potatoes became an important crop by the late 18th century, and particularly the staple of Ireland’s impoverished citizens in the years leading up to the Irish Potato Famine of the mid-1840s.

Today, potatoes are one of the world’s most important crops, grown in every continent except Antarctica. Known scientifically as Solanum tuberosum, it was given this name by the famous Swedish naturalist, Carl Linnaeus in his 1753 magnum opus, Species Plantarum.

The potato and its wild relatives must be one of the most studied groups of crop plants. Not that I’m biased (having researched potatoes for more than 20 years).

Potato diversity and germplasm collections
Its clear that there is a wealth of information about the diversity within the section of the genus Solanum that encompasses the potato. They have been studied extensively from a taxonomic point of view, breeding efforts worldwide have incorporated genes from many wild species to enhance productivity, and important germplasm collections were set up decades ago to preserve this important diversity, to study it, and use it in potato breeding.

My former colleague (and fellow PhD student at Birmingham), Dr Zosimo Huaman, describes the management of CIP’s wild potato collection in Huancayo to members of the CGIAR’s Inter-Center Working Group on Genetic Resources who held their annual meeting at CIP in 1996.

Among the most important collections are held at:

The wild relatives of the potato have one of the broadest geographical and ecological ranges among species that have been domesticated for human consumption. While the various forms of cultivated potatoes were domesticated in the Andes of Peru and Bolivia, and on the coast of Chile, the wild species are found from the southwest USA (in the coniferous forests of Arizona, for instance) through Mexico and the countries of Central America to Panama, along the Andes south to Chile and northern Argentina, and south and east on to the plains of Argentina, Brazil, Paraguay and Uruguay. Wild species are found in the coastal desert of Peru, in the cloud forests of central America to almost 3000 m, at the highest altitudes of the Andes, well over 4000 m, and also growing in the highly humid transition zone on the eastern side of the Andes dropping down to the lowland forests (known as the ‘eyebrow of the mountain’ or ceja de la montaña).

Here is just a very small sample of the diversity—and beauty—of wild potato species (photos courtesy of my friends at the Commonwealth Potato Collection).

How many potato species are there?
Well, it depends, to some extent, on one’s perspectives as a taxonomist, use of different species concepts, and the methods used to study species diversity, and also on the work that earlier taxonomists published.

Essentially, there are three basic taxonomic approaches:

  • Morphology: often based on the study of dried herbarium specimens collected in the wild. In the case of potatoes, this has led to the description of a multiplicity of species, with almost every variant being described as a separate species. This reliance on plant morphology was the approach taken by the 19th and early 20th century botanists.
  • Biosystematics: takes an experimental view of species diversity, of breeding behaviour and relationships, and very much based on collections in the field and the study of ecology, and growing samples in a uniform environment such as the study one of my PhD students, Susan Juned, made of Solanum chacoense, a species from Argentina and Paraguay.
  • Molecular biology: methods have become available in the last couple of decades to analyse the most basic variation in DNA, and helped to refine further how potato taxonomists view the diversity within the tuber-bearing Solanums, and the relationships between species.

While these different approaches still do not provide a definitive answer to the question of how many species there are, we know that taxonomists have described and named more than 200 species. To some extent it’s like asking how long is a piece of string. And that helps me to provide an analogy.

Take a piece of string. If you were to view this string along its length that, to your vision would be fore-shortened, it would be very difficult to say with any degree of certainty just how long the string actually was. However, if you increase the angle at which you view the string, until you are looking at right angles, your ability to estimate its length also increases. At right angles you can see the whole length, and measure it accurately in many different ways.

Taxonomic study is a bit like looking at the string from different angles. Each taxonomist builds on earlier studies, and describing new species or subsuming previously described ones into another species (as merely variants). This is one of the challenges of studying wild potato species: they are highly variable and show considerable phenotypic (or morphological) plasticity. It’s not always possible to study large numbers of plants under uniform conditions to reduce the variation caused by differences in habitats.

The 2n=3x=36 chromosomes of a triploid potato, from a root-tip squash in two cells.

Furthermore potatoes have considerable chromosomal variation, with a base number of x=12, with diploids (2n=24) the most frequent, and mostly self-incompatible (i.e. they cannot self fertilise), infertile triploids (2n=36, including two cultivated species), tetraploids with 2n=48 (mostly self-fertile, and including the cultivated Solanum tuberosum of world-wide agriculture), some pentaploids (2n=60; including one cultivated form), and a few hexaploids with 2n=72. Wild potatoes are uncommonly promiscuous when grown together under experimental conditions, and will inter-cross readily (they are bee-pollinated), yet hybrids often do not survive beyond the second generation in the wild. Many species are separated by ecology, and generally do not come into contact with each other, thus maintaining their species identity.

Nevertheless, this is what makes the study of potatoes and wild species so very interesting, and that captured my interest directly for over two decades, and continues to do so, even though I moved on to the study of other crops like rice and grain legumes.

The potato taxonomists
Many botanists have taken an interest in wild potatoes. During the 19th century, the Swiss-French botanist Alphonse de Candolle (d. 1893) named a number of species, as did François Berthault (d. 1916). But the first decades of the 20th century leading up to the Second World War saw a lot of collecting and taxonomic description. In Germany, Friedrich August Georg Bitter, who specialised in the genus Solanum, described and named many species. However, it was the involvement of several Russian botanists and geneticists, under the leadership of Nicolai Vavilov, that saw an expansion in the collection of potatoes throughout the Americas, but a systematic evaluation of this germplasm leading to even more species being described.

SM Bukasov

Two names come to mind, in particular: SM Bukasov and VS Juzepczuk. They were active during the 1920s and 30s, taking part in several missions to South America, and developing further the concept of potato species. But much of their work was based on morphological comparison leading to the identification of even small variants as new species.

In August 1938, a young Cambridge graduate, Jack Hawkes, traveled to Leningrad in Russia to meet and discuss with Bukasov and Juzepczuk (and Vavilov himself) in preparation for the 1938-39 British Empire Potato Collecting Expedition to South America (which Jack has described in his 2004 memoir Hunting the Wild Potato in the South American Andes [2]).

A young Jack Hawkes (second from right) stands outside a church near Lake Titicaca in northern Bolivia, alongside expedition leader Edward Balls (second from the left).

Jack Hawkes

That collecting expedition, and the subsequent studies (which led to Hawkes being awarded his PhD from the University of Cambridge in 1941 for a thesis Cytogenetic studies on South American potatoes supervised by renowned potato scientist Sir Redcliffe N Salaman), was the launch pad, so to speak, of potato taxonomy research for the rest of the 20th century, in which Hawkes became one of the leading exponents.

After Cambridge, Hawkes spent some years in Colombia (where he no doubt continued his studies of wild potatoes) but it was on his return to the UK in 1952 when appointed to a lectureship in the Department of Botany at The University of Birmingham (where he was to remain until his retirement in 1982) that his potato studies flourished, leading him to publish in 1956 his first taxonomic revision of the tuber-bearing Solanums (with a second edition appearing in 1963).

In 1990, he published his final synopsis of the tuber-bearing Solanums [3]; that taxonomic treatment is the one followed by the curators of the Commonwealth Potato Collection.

Jack’s approach to potato taxonomy was based on a thorough study of morphology backed up by rigorous crossing experiments, and a cytogenetic and sometimes serological evaluation of species relationships.

I first met Jack in February 1970 when he interviewed me for a place on his newly-founded MSc course on plant genetic resources, joining the course later that same year. In September 1971 I became one of Jack’s PhD students, joining others who were looking at the origin and evolution of the cultivated species [4].

Donovan S CorrellIn these revisions he was also taking into account the work of US botanist, Donovan S Correll who published his own potato monograph in 1962 [5], as well as three important South American botanists with whom he would collaborate from time-to-time: Professor César Vargas from the National University of Cuzco; Professor Martín Cárdenas from Cochabamba in Bolivia; and Professor Carlos Ochoa, originally from Cuzco, who was a professor at the Universidad Nacional Agraria (UNA) in La Molina, Lima and, around 1975 or so, joined the International Potato Center across the street from the UNA.

Vargas published a number of species descriptions in the 1950s, but made his most significant contribution in his two part monographs, Las Papas Sudperuanas published in 1949 and 1956. I met Vargas on a couple of occasions, first in January 1973 just after I’d joined CIP as Associate Taxonomist. And a second time in February 1974 when I was passing through Cuzco with Dr Peter Gibbs from the University of St Andrews in Scotland. Peter was making a study of incompatibility among different forms of the Andean tuber crop, oca (Oxalis tuberosa), and had joined me on an excursion to Cuyo-Cuyo in the Department of Puno. Vargas’s daughter Martha was studying for her MSc degree under Peter’s supervision at St Andrews.

It was Carlos Ochoa, however, whose studies of potatoes and their relatives rivalled (and in some respects eclipsed) those of Jack Hawkes. They were quite intense taxonomic rivals, with a not-altogether harmonious relationship at times. Carlos certainly played his taxonomic cards very close to his chest.

Me consulting with Carlos Ochoa concerning the identity of some triploid potatoes, in one the screenhouses at the International Potato Center in 1974.

But the fact that he grew up in the Andes and had, from an early age, taken an interest in the diversity of this quintessential Andean crop and its wild relatives, led him to dedicate his life to uncovering the diversity of potatoes in his homeland. He was also a potato breeder and released some of the most important varieties in Peru, such as Renacimiento, Yungay, and Tomasa Condemayta.

In this video (in Spanish, and broadcast on Peruvian TV on his death in 2008) he talks about his early life in Cuzco, the pressures on him to study medicine or become a lawyer, and how he found his true vocation: the study of wild potatoes.

Setting potato taxonomy and germplasm exploration priorities at CIP
Forty-five years ago this week, CIP convened the first planning workshop on the exploration and taxonomy of potatoes [6], inviting a group of taxonomists and potato breeders to meet in Lima and mull over the ‘state of play’ taking into consideration what taxonomic research had already been accomplished, what was in the pipeline, and what CIP’s germplasm exploration policy (especially in Peru) should be. I attended that meeting (as an observer), having landed in Lima just a few days earlier.

On the taxonomic side were Jack Hawkes, Carlos Ochoa, and Donald Ugent who was a ethnobotany professor at Southern Illinois University in Carbondale. Richard Tarn, a potato breeder from Agriculture Canada at Fredericton, New Brinswick, had completed his PhD under Jack’s supervision at Birmingham. Frank Haynes, a professor of genetics and potato breeder at North Carolina State University (and long-time friend and colleague of CIP’s first Director General, Richard Sawyer) and Roger Rowe [7], then curator of the USDA’s potato collection at Sturgeon Bay (who would join CIP in July 1973 as the Head of Breeding and Genetics, and become my PhD co-supervisor) were the other participants.

In 1969, Jack had published (with his Danish colleague Peter Hjerting [8]) a monograph of the potatoes of southern cone countries of South America [9], and by the time of the CIP 1973 workshop was well into research on the potatoes of Bolivia [10], leading publication of a monograph in 1989.

What I’ve never been able to fathom after all these years is why Ochoa decided to write his own monograph of the Bolivian species rather than concentrating in the first instance on the Peruvian species. Nevertheless Ochoa did produce his own fine monograph in 1990 [11], beautifully illustrated with some fine watercolours by CIP plant pathologist Franz Frey. This was followed by an equally magnificent volume on the potatoes of Peru in 2004 [12], also illustrated by Frey.

Throughout his expeditions and research, Ochoa was supported by several assistants, the most notable being Ing. Alberto Salas. Now in his mid-70s, he has been collecting wild potatoes for five decades.

I knew Alberto when I first joined CIP in 1973, and it was a delight to meet him again (although he had retired) during my visit to CIP in July 2016.

Taking up the baton
With retirement, Hawkes and Ochoa passed the potato taxonomy baton to a new generation of researchers, principally David Spooner, a USDA scientist at the University of Wisconsin-Madison who made several collecting trips throughout the Americas.

David Spooner

David’s research took potato systematics to a new level, employing the developing molecular and genomic approaches, and use of different classes of markers to help him refine his understanding of the diversity of the tuber-bearing Solanums, building of course on the very solid Hawkes and Ochoa foundations.

Although no longer working on potatoes (his most recent focus on carrots supported the PhD thesis of Carlos Arbizu, Jr, the son of one of my PhD students at Birmingham in the 1980s), David’s scientific output on potatoes has been prodigious. With molecular insights supporting more traditional methods he has proposed a 50% reduction in the number of potato species from the more than 200 listed in Hawkes’s 1990 publication.

Is this the end of the potato taxonomy story? Probably for the time-being. It’s unlikely that anyone will pursue these studies to the same depth as Hawkes and Hjerting, Ochoa, or Spooner. Nevertheless, as the curators of the Commonwealth Potato Collection have done, most potato researchers will take a pragmatic approach and fix on a particular taxonomic treatment on which to base their management or use of germplasm. Taxonomy is one of those disciplines in which subjective interpretations (obviously based on empirical studies of diversity) can lead to contrary classifications. What is a distinct species to one taxonomist may be merely a variant to another. Undoubtedly these different taxonomic treatments of the tuber-bearing Solanums have permitted us to have a much better appreciation of just how long ‘the potato piece of string’ really is.

[4] Since I was working on the origin and evolution of a cultivated species of potato for my PhD, I made only one short collecting trip for wild species with Jack in early 1975, to the Departments of Huanuco, Cerro de Pasco, and Lima. On his trips to Peru between 1973 and 1975 he would join me in the field to look at the germplasm I was studying and give me the benefit of his potato wisdom.

[7] I’ve kept in touch with Roger and his wife Norma all these years. After I left CIP in 1981, Roger moved to East Africa to work with the animal diseases center that became ILRI after its merger with another CGIAR livestock center in Ethiopia. He was DDG-Research at CIMMYT in Mexico in the late 1980s and early 1990s. While I was at IRRI, he was based in Cairo working for the CGIAR center that became WorldFish (with its headquarters in Penang, Malaysia). Before it moved to Malaysia, ICLARM as it then was had its offices in Manila, and we would see Roger in the Philippines from time-to-time. It was great to meet up with Roger and Norma again in July 2016 when I was in Lima for the genebank review that I led.

[8] From what I can determine through a Google search, as of January 2018, Peter celebrated his 100th birthday in 2017. He has a Mexican tetraploid (2n=4x=48) species named after him, Solanum hjertingii. When I was at Birmingham in the 1980s I had two PhD students, Lynne Woodwards and Ian Gubb who studied this species because its tubers lack so-called enzymatic blackening, a trait that could be very useful in potato breeding.
