German botanist and pteridologist, wife of Dr. Kurt Rasbach.

Helga was also an outstanding botanical illustrator – from cytology (e.g., of ferns) to the overall habitat (e.g., in her husband's early orchid volume).

Longtime collaborator with her husband Dr. Kurt Rasbach. Members of the Baden State Association for Natural History and Nature Conservation for over 60 years.

[Translated from German via Google,
Helga Rasbach was a biologist who specialized in the taxonomy of ferns. Her specialty was the discovery of unusual species. Numerous new discoveries of fern species in Central and Southern Europe can be traced back to her. At the same time, Helga Rasbach possessed the systematic knowledge to identify and thoroughly investigate doubtful cases in the field, particularly to examine them cytologically with regard to the chromosome numbers of individual ferns. Based on this, she was able to describe new hybrids, cytotypes, and subspecies of ferns and to identify hybrids. She also contributed many anonymously, for example, her work on the identification key for ferns in Oberdorfer's Excursion Flora.

Supported, among other things, by his early membership in the Baden State Association for Natural History and Nature Conservation, the Rasbachs maintained diverse contacts within the natural science community in Tübingen, Freiburg, and Karlsruhe. Especially in geobotanical work, they supported projects by young scientists at the diploma thesis level, many of whom later became professors. Here, too, the Rasbach couple proved themselves to be a perfect team: Helga Rasbach meticulously prepared the thematic requirements for photographic documentation of the relevant questions and results. Over the weekend, they both worked through the assigned tasks – and on Sunday night, the results were produced together in their own darkroom.

The series of publications on the most important nature reserves of the former LfU Karlsruhe would be virtually inconceivable without the Rasbach couple. For the first editions of the volume "Kaiserstuhl," they were both responsible for the editorial work. The "Feldberg" book from the same series was also edited by them and received all the photographic material from them.

Both played a prominent role in the major species conservation works of the State Institute.

The eight-volume vascular plant flora, the moss flora, and the lichen flora contain many hundreds of illustrations by Helga and Kurt Rasbach.

The last major project they jointly undertook was the design of the 4th edition of the
Kaiserstuhl book – published in 2009. Helga and Kurt Rasbach did not complete the transition from
analog to digital photography, which was almost finished at that time, although they had a
lively interest and continually critically examined the new possibilities.

For Helga and Kurt Rasbach, illustrations were not merely an accessory or illustration, but rather,
in the field of natural history, a first-rate source that describes more about the nature and structure of an organism than would be possible in text form. They both left behind many
plans for future publications and an image archive of approximately 400,000 black-and-white negatives and colour slides, which is currently being prepared for further use.

Went to the University of Exeter to take an Honours Degree in Botany. In 1961, she moved to the botany department at the University of Leeds to become a research student of Professor Irene Manton. Anne's area of research was in two genera: Asplenium and Polystichum. She investigated the relationship between diploid taxa and the evolution of polyploids.

Many aspects of her work can be found in her 1966 dissertation, "Some cyto-taxonomic problems in the fern genera Asplenium and Polystichum," which, unfortunately, was never published and therefore only exists in a few copies. She was then awarded a research fellowship to spend two years in Japan from 1967 to 1969 to continue her work on ferns. She recalled this as a formative experience in her life. It allowed her to travel extensively in the East and establish a broad circle of professional and personal friendships.

Anne had barely returned from Japan when she developed systemic sclerosis, a rare and debilitating disease that proved difficult to diagnose and treat. This illness increasingly restricted her and made it less and less possible for her to pursue scientific work. Despite the great difficulties arising from her illness, she continued to expand her research, though the practical fern work proved increasingly difficult. Eventually, her illness began to affect her heart, and she eventually succumbed to the disease.

The Anne Sleep Award (The Linnean Society), Established by Mrs. Ivy Sleep in fulfilment of the wishes of her daughter, Dr Anne Sleep FLS. Awards of up to £3,000 are made at (odd-numbered) two year intervals, to assist one or more scholars to carry out biological research in the Middle or Far East, or similarly for scholars from the Middle or Far East to pursue their own biological research in the UK.

Mrs. Ivy Sleep, died in 1996 and left the sum of £120000 to the Linnean Society of London in fulfilment of her daughter’s wishes.

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 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.
