Francis Hugh Adam Marshall CBE FRS[1] FRSE LLD (11 July 1878 – 5 February 1949) was a British physiologist who did pioneering early research into the physiology and endocrinology of biological reproduction.
He subsequently studied the oestrus cycle of ferrets (with Edward Schäfer) and dogs (with William A. Jolly).
[citation needed] In 1908, Marshall returned to the University of Cambridge, lecturing in the School of Agriculture, and becoming a Reader in 1919.
His studies of reproduction were interrupted by the First World War, during which he did research for the Ministries of Food and Agriculture, for example on the optimal age to slaughter cattle.
[3] In 1901 Marshall was elected a Fellow of the Royal Society of Edinburgh; his proposers were James Cossar Ewart, Arthur Masterman, Robert Wallace and Cargill Gilston Knott.
