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)

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. Hugh built on McTimoney's work and founded the Oxford College of Chiropractic.

An Italian botanist. He was a specialist on the ecology and phytogeography of tropical Africa, and also worked in plant taxonomy and pteridology.

In 1935, he graduated with a degree in Natural History from University of Florence.

From 1935 to 1958, was an assistant at the Institute of Botany in the University of Florence.

From 1958 to 1959 became a professor of botany at the University of Sassari in Sardinia.

From 1959, Rodolfo was a professor at the Institute of Botany in the University of Genoa and director of the Botanical Garden.

Pichi was a member of the Linnaean Society of London, the Botanical Society of America and the American Society of Ferns, he received the Hailé Selassié prize for his work in Ethiopia. He was also made a professor emeritus by the University of Perugia, Italy.

English botanist and writer. Specialised in the growth and cultivation of orchids. Later in his life he studied ferns.

Studied at University of Cambridge, studies were interrupted by WWI. He volunteered in France with the Friends' Ambulance Service. Returned to his studies at Cambridge in 1920 received a degree in Natural Sciences Tripos.

From 1920-1922 he worked at Cambridge University as a junior demonstrator. In 1922, he was appointed by the Colonial Office as assistant director at the Singapore Botanical Gardens. Promoted to Director in 1925, a role he would keep for the next 20 years.

During WWII, Japan occupied Singapore. Holttum was placed under house arrest while he continued to work at the Garden but he was relieved of his administrative duties. During this time he was able to concentrate on research. He wrote a number of drafts for books that would be published after the war. These include: "Gardening in the Lowlands of Malay" and the first two volumes of "A Revised Flora of Malaya."

Founding member and president of the Singapore Gardening Society. Was also a founding member of the Malayan Orchid Society.

In 1949, he left the Botanic Garden and became the first Chair of Botany at the University of Malaya until his retirement in 1954.

After retirement Holttum returned to England and began spending time at Royal Botanic Gardens, Kew. Here he continued his research and contributed to the Pteridophyta in the Flora Malesiana project.

Holttum penned about 500 scientific texts, largely on ferns and orchids, but also dealing with bamboos, gingers and the Marantaceae family. Many plant taxa are named in his honour, including the fern genus Holttumiella Copel.

Chinese botanist, known as the father of Chinese pteridology. Wrote the first complete monograph of Chinese Ferns. He published over 160 articles and monographs, as well as 15 translations.

Developed the Ren-Chang Ching System for ferns. In 1940, Ren-Chang Ching published the Natural Classification System of Polypodiaceae, in which he divided plants of Polypodiaceae into 33 families and 249 genera, and proposed 5 evolutionary clues (Xing, 1994). His system ended the conservative classification system of Joseph Dalton Hooker and solved the biggest problem of fern botany at that time, which made great contributions to the worldwide fern taxonomy.

Became interested in botany when studying at the First Agricultural School in Jiangsu Province. After graduation, he attended the University of Nanking and got a bachelor degree in forestry.

Ren-Chang, went on to work as an assistant at Southeast University and later got a job with the Natural History Museum of Academia Sinica.

In 1929, he began researching ferns at the Botany Museum at the University of Copenhagen (Denmark). After returning to China, he worked as a researcher at the Institute of Hydrobiology in Peiping. In 1934, he was sent to Jiangxi to establish the Lushan Botanical Garden and became its director.

During the War of Resistance against Japan, he established a fern research center in Kunming. From 1945, he became an associate professor at the Department of Forestry and Biology of Yunnan University.

In 1949, he also became the Deputy Director of the Forestry Bureau of Yunnan Province.

In order to study ferns he learned English, French, Latin, and other languages.

He took over 18,300 photographs of fern patterns.
