Benson was born 20 October 1859 in London to William Benson and Edmunda Bourne, who was the daughter of the landscape painter James Bourne.[5] Benson's mother was also a painter and exhibited at the Royal Academy of Art.[6]
Benson was introduced to botany by her father, an engineer and architect with an interest in the subject.[5] She was first educated by her sister, who had attended Queen's College.[4] In 1878–9 she studied Classical Studies for one year at Newnham College, Cambridge, before working for seven years as a teacher at Exeter High School in order to have the finance for university study.[7][8] She then matriculated to University College London in 1887 and earned her bachelor's degree in Botany with first class honors from the university in 1891.[7][2] She gained a Marion Kennedy research scholarship[7] and earned her doctorate in 1894 from the University of London, working with Francis Wall Oliver.[5] Her work focused on embryology of a category of Fagales that were called Amentiferae at the time.
Work and achievements
Benson started working as a lecturer at Royal Holloway College in 1889.[7] Benson was appointed head of the Botany Department at Royal Holloway College in 1893,[5] and remained so until her retirement in 1922. She was the first female Botanist to become a department head in the UK.[2] In 1897, Benson travelled around Europe with Ethel Sargent to gain equipment and knowledge to set up the department.[9] Benson is also credited with planning and stocking the Botanical Garden, Herbarium and Museum.[5]
Benson made various collecting trips for botanical material, including to Australia in 1905–1906, and to Australia, Java and India in 1914-15.[5] Her observations of herbaceous plants from the early Paleozoic era and the earliest true ferns are considered notable.[5] She proposed a model for the evolution of the ovule,[10] which remains a likely explanation.[2] She also described the species Cordaites felicis found in coal deposits in England.[11] To adopt the new technique of microscopic anatomy of fossils, she cut sections herself with a gas-powered machine in her garden shed.[8] Her papers are characterised by precise drawings and wash-paintings which are believed to be produced by Benson herself.[2]
Upon her retirement in 1922,[5] Benson was succeeded by Professor Elizabeth Marianne Blackwell as Head of Botany at Royal Holloway College. Benson died in Highgate on 20 June 1936, and Blackwell authored Benson's official obituary.[4]
