British physiologist born in London in 1899 and died in Cambridge in 1977, author of important works on the physiology of the nervous system and Nobel Prize for Physiology and medicine in 1932.
He studied at the Trinity College of the University of Cambridge, where he/she graduated in 1911 with the highest qualifications. His interest in the mechanisms of nerve transmission led him to accept a medical position in the military Hospital of Connaught during the first world war, where he/she investigated various nerve lesions and neuroses that afflict the Allied soldiers. In 1920 was of Professor at the Department of Physiology at Cambridge and, three years, most later joined as a member in the Royal Society. In November 1925 he/she managed to register the propagation of the pulse in a single afferent nerve fiber with capillary electrometer Lucas. He/She managed to explain the mechanism of transmission of nerves with the help of Dr. Zotterman, and later developed a method to convert audible signals the electrical impulses from the nerves, in collaboration with Dr. Bronk. In 1932 he/she received, along with Ch. Sherrington, Nobel Prize in medicine, and the order of merit in 1942. His interest was decanted since 1934 by the electrical activity of the brain. He/She was named baron in 1955, and served as President of the Royal Society between 1950 and 1955. He/She was Vice-Chancellor of Cambridge University from 1957 to 1958. Among his publications deserve mentioning the basis of sensation (1928), the mechanism of nervous action (1932) and the physical basis of perception (1947), works of obligatory reference in neurophysiology.
