Edgar Adrian

Edgar Douglas Adrian, 1st Baron Adrian (1889 to 1977) was an English electrophysiologist who shared the 1932 Nobel Prize for Physiology with Sir Charles Sherrington for work on the function of neurons, and who provided experimental evidence for the all-or-none law of nerves. Born in Hampstead, London, he studied Natural Sciences at Trinity College, Cambridge, graduating in 1911, and was elected to a fellowship of the college in 1913. After wartime clinical work at St Bartholomew's Hospital in London he returned to Cambridge as a lecturer, and from 1925 he researched the human sensory organs by electrical methods, using a capillary electrometer and cathode-ray tube to record the electrical discharge of single nerve fibres.
