He then became a medical student and carried out an investigation into stomach movements using the technique of radio-opaque meals, initially in a cat. He qualified in medicine from Harvard in 1900 and was soon appointed Assistant Professor of Physiology. In 1906 he succeeded to the Chair of Physiology, which he held for thirty-six years.Apart from his early work, Cannon's demonstration of the humoral transmission of the nerve impulse was fundamental, as were his investigations, including researches on himself and his colleagues, into the relationship between emotion and the sympathetic-adrenal system.During the First World War he served with both the British and American armies and was decorated.[br]Principal Honours and DistinctionsDSM (USA).

After five years of farm and factory jobs accompanied by night study, he gained admission to Columbia University, New York, in 1879. He graduated in 1883 and after a period at Cambridge University, England, worked under Helmholtz in Berlin. He received his doctorate in 1889.He returned to Columbia and, apart from his involvement in X-ray diagnosis in 1896, was engaged in practical work in connection with problems in telegraphy and telephony, radio transmitters and electrical network theory. In 1901 he was appointed Professor of Electromechanics, a post that he held for thirty years. He acted as an adviser on behalf of Yugoslavia at the 1919 Peace Conference.[br]Principal Honours and DistinctionsMember of the National Academy of Sciences.
