Elke Mackenzie
Elke Mackenzie (11 September 1911 – 18 January 1990), born Ivan Mackenzie Lamb, was a British polar explorer and botanist who specialised in the field of lichenology. Early life. Mackenzie was born in Clapham, London, on 11 September 1911. Mackenzie's family moved to Scotland while she was a child, and she was enrolled in the Edinburgh Academy. After her graduation in 1929, she attended Edinburgh University. She earned her B.Sc. with Honors in Botany in 1933. She received a scholarship from the German Academic Exchange Service, and continued doing research in botany at the University of Munich and  the University of Würzburg. Career. Mackenzie was appointed as an assistant keeper at the British Museum (Natural History) in 1935 under the direction of lichenologist Annie Lorrain Smith. Mackenzie became especially interested in the lichen flora of the antarctic, as it was comparatively unknown, and she began studying early British, French, and Belgian antarctic collections in Turkey and Paris. She earned her Doctor of Science from Edinburgh University in 1942. Mackenzie is famous for her part in Operation Tabarin, a secret mission instigated by Churchill during the Second World War. On the surface, it was an antarctic expedition organized to  demonstrate British sovereignty in the Antarctic Peninsula. Mackenzie joined the crew in 1943. She collected lichen samples and conducted experiments on the accumulation of snow and subsequent thawing. Mackenzie discovered a number of lichen species, including "Verrucaria serpuloides", the only known true marine lichen. Mackenzie remained in Antarctica until 1946. After the war, Mackenzie became Professor of Cryptogramic Botany at National University of Tucumán and traveled extensively in Argentina and Brazil. In 1950, Mackenzie was put into contact with Erling Porsild, who hired her as a cryptogamic botanist at the National Museum of Canada in Ottawa. After the move to  Canada, Mackenzie sold her private herbarium of 3,200 specimens to the Canadian Museum of Nature. She continued to collect, gathering specimens from all throughout Canada. In 1953, Mackenzie was offered the directorship of the Farlow Herbarium of Cryptogamic Botany by Harvard University, and she left Canada. Mackenzie returned to Antarctica in October 1964, where she began SCUBA investigations with her colleagues from France and Argentina, under a grant from the National Science Foundation and with the logistic support of the Argentine Navy. Mackenzie referred to this study as "Operation Gooseflesh." For the three following years, she continued to collect throughout  Europe and Mexico. Mackenzie had a rivalry with Carroll William Dodge, citing the latter's "reckless taxonomy". Personal life. In 1971, Mackenzie was diagnosed with gender dysphoria, underwent a sex reassignment surgery, and renamed herself from Ivan Lamb to Elke Mackenzie. She joined a theater troupe under direction of Laurence Senelick. Mackenzie retired from the Farlow Herbarium in 1972. Senelick stated that Mackenzie was forced into retirement after her transition. During the next six years, Mackenzie lost interest in her botany work, preferring to translate German botanical text books into English. She constructed an A-frame bungalow in Costa Rica , and moved there in 1976. In 1980, Mackenzie returned to Cambridge to live with her daughter, citing political unrest. She took up woodworking, but was diagnosed with Lou Gehrig's disease in 1983. She died in 1990. Her lifelong work on a monograph of "Stereocaulon" was never completed. Legacy. Mackenzie is the namesake of two genera, "Lambia" and "Lambiella", and several species. The list of species includes: Cape Lamb on Vega Island is named for Mackenzie. Awards. Mackenzie was the recipient of both the British and United States Polar Medals for her involvement in Operation Tabarin. Selected publications. Mackenzie published  43 papers over a 43-year period.
