Roberts, Richard Henry
Persona · 1910-2003

One of the UK's leading amateur botanists and nature conservationists from Wales. He co-founded the North Wales Naturalists' Trust (North Wales Wildlife Trust) and was the organisation's first General Secretary. He had an international reputation for his expertise in Polypodium, Dactylorhiza, and Mimulus.

Educated at the University College of Wales, Bangor. He received no formal education in botany at school or university. He spent his whole career working as a primary school teacher.

In 1947, he was appointed to teach at Penmachno, Wales. This allowed him to study the mountain flora of Eryri (Snowdonia). He had a particular interest in ferns. Roberts studied the distribution patterns of plants against rock types.

In 1955, he and his family moved to Bangor, Wales, where he was appointed head teacher until his retirement in 1974.

Roberts was an active member of the British Pteridological Society (BPS) and the Botanical Society of the British Isles (BSBI) for almost 50 years. From 1955 to 1995, he was the BSBI Vice County Recorder for Anglesey (VC52).

After extensive fieldwork, Roberts published 2 books:

  • The Flowering Plants and Ferns of Anglesey (Cardiff: National Museum of Wales, 1982)
  • An Atlas of the Flowering Plants and Ferns of Anglesey (The Author, 2002)

In his lifetime, he would also publish nearly 50 scientific articles and papers on his own and was formally acknowledged in more than 20. Roberts' work was recognised in the naming of two taxa: Mimulus x robertsii and Equisetum x robertsii.

Roberts was always happy to share his knowledge and experience. Often advising university staff and students, professional conservationists, taxonomists, and fellow amateur botanists.

In 1979, Roberts developed a strong relationship with the University at Bangor and, in recognition of his botanical and conservation work, was awarded an Honorary MSc by the University of Wales. He also became an Honorary Member of the BSBI and was awarded the Linnean Society's H.H. Bloomer Medal for services to botany and conservation in 1999.

Roberts was described as a very modest man who was content with working quietly without acknowledgement. His other interests included archaeology, Welsh history, poetry, and Welsh Mountain sheep breeding.

Corley, Hugh Vanner
Persona · 7 October 1914 -19 October 2002

An amateur botanist from Pucketty Farm, Faringdon, England.

Born in South India in 1914. He left India at age 4 to attend school in England. Eventually attended Marlborough College and Oriel College, Oxford, with a degree in zoology.

After a brief period in the army, he took up farming, working as a pupil on a farm near Kelmscott. In 1938, Hugh bought Pucketty Farm in Faringdon. He became an organic farmer and eventually published a book on the subject. Many people would come to his farm to learn about organic farming.

During WWII, Hugh was told by the Gloucester Regiment that they did not need him, so he resigned his commission and continued farming. He joined the Home Guard.

In 1950, Hugh became interested in ferns when he happened upon a very rare fern by chance. For the next 50 years, he dedicated himself to the study of ferns. He joined the British Pteridological Society in 1962 and began to specialise in Dryopteris. He was the first to suggest formulae (e.g. AB, AAB) for the possible combinations of genomes in what later became the subspecies of Dryopteris affinis, work that is still being continued today. President of BPS, Stanley Walker, lent him an old microscope so he could check spores.

Hugh would carry out fieldwork in Southern England and Wales on the weekends when the farming calendar would allow. In 1982, while fern hunting in Kintyre, he made the first discovery of Dryopteris x sarvelae outside Finland.

Hugh built up a living fern collection at Pucketty. Care of his ferns was his top priority, and they were well taken care of. Many of his plants were later studied in depth by Stanley Walker and Mary Gibby at the BM. Under Walker's tutelage, Hugh quickly learned to detect the exact stage when developing spores could be stained to show their chromosomes.

Hugh was a kind and generous person who was always willing to help anyone who showed an interest in ferns. One such person was a young student from Radley College, Christopher Fraser-Jenkins. They developed a long-lasting friendship, and Christopher would go on to name a species of Dryopteris after Hugh: D. corleyi.

In his 70s, Hugh trained as a chiropractor, being one of the first students of John McTimoney, founder of the Oxford College of Chiropractic. Hugh built on McTimoney's work.

Howie, Francis
Persona · fl 1960s-2022

Safety Officer at Natural History Museum, London.

[From NHM Archive]
Frank working at the Museum in the early 1970s in what was then known as the Palaeontology Laboratory. With a background of chemistry, Frank worked on conservation methodology and published numerous books and articles on the care and conservation of geological material.

He is well known for his early pioneering work on identification and treatment for pyrite as well as using thioglycolic acid to remove haematite from vertebrate specimens.

In 1984, Frank was appointed Safety Officer and helped establish the Museum’s first Health and Safety division. He continued his academic interests and published on aspects of safety in Museums and Galleries.

Frank retired to Cornwall in the early 2000s where his longstanding interest in natural sciences led him to become a member and later chair of Cornwall Geoconservation Group and he was appointed a Trustee of Cornwall Wildlife Trust. He had been actively working and preparing a publication on the recent geological history of Cornwall.

Cannon, John Francis Michael
Persona · 22 April 1930 - 31 March 2008

Keeper of Botany at Natural History Museum, London from 1977-1990 (retired).

After military service and study at Newcastle University, Cannon joined the Natural History Museum in 1952 as a Scientific Officer in the General Herbarium. The range of families in his section included the Umbelliferae (Parsley Family), of which he made a special study, particularly of the African species. One of his first tasks was to supervise the creation by Kim Allen of the old British Natural History Gallery. John Cannon was made Deputy Keeper under Bob Ross in 1972, and became Keeper of Botany on Bob’s retirement in1977. When he himself retired in 1990, he left the Museum and gave up botanical research. However, along with his wife Margaret, he wrote a book on Plant Dyes, published by the Museum.

President of Botanical Society of the British Isles (1983-1985)
