He devoted his career to diverse topics in physiology and biochemistry, but was chiefly interested in carbohydrate metabolism. He is noted for his role in the discovery and isolation of insulin during his tenure as a lecturer at the University of Toronto, for which he and Frederick Banting received the 1923 Nobel prize in Physiology or Medicine. Awarding the prize to Macleod was controversial at the time, because according to Banting's version of events, Macleod's role in the discovery was negligible. It was not until decades after the events that an independent review acknowledged a far greater role than was attributed to him at first.","summary_more":[],"facts":[{"key":"born","label":"Born","values":[{"text":"6 September 1876","date":"1876-09-06"}],"source":{"label":"Wikidata","url":"https://www.wikidata.org/wiki/Q232024#P569"}},{"key":"birthplace","label":"Place of birth","values":[{"text":"Clunie","wikidata":"https://www.wikidata.org/wiki/Q3776576"}],"source":{"label":"Wikidata","url":"https://www.wikidata.org/wiki/Q232024#P19"}},{"key":"died","label":"Died","values":[{"text":"16 March 1935","date":"1935-03-16"}],"source":{"label":"Wikidata","url":"https://www.wikidata.org/wiki/Q232024#P570"}},{"key":"deathplace","label":"Place of death","values":[{"text":"Aberdeen","wikidata":"https://www.wikidata.org/wiki/Q36405"}],"source":{"label":"Wikidata","url":"https://www.wikidata.org/wiki/Q232024#P20"}},{"key":"citizenship","label":"Citizenship","values":[{"text":"United Kingdom","wikidata":"https://www.wikidata.org/wiki/Q145"}],"source":{"label":"Wikidata","url":"https://www.wikidata.org/wiki/Q232024#P27"}},{"key":"occupation","label":"Occupation","values":[{"text":"physician","wikidata":"https://www.wikidata.org/wiki/Q39631"},{"text":"inventor","wikidata":"https://www.wikidata.org/wiki/Q205375"},{"text":"university teacher","wikidata":"https://www.wikidata.org/wiki/Q1622272"},{"text":"physiologist","wikidata":"https://www.wikidata.org/wiki/Q2055046"}],"source":{"label":"Wikidata","url":"https://www.wikidata.org/wiki/Q232024#P106"}},{"key":"education","label":"Education","values":[{"text":"University of Aberdeen","wikidata":"https://www.wikidata.org/wiki/Q270532"},{"text":"University of Aberdeen School of Medicine","wikidata":"https://www.wikidata.org/wiki/Q7895005"}],"source":{"label":"Wikidata","url":"https://www.wikidata.org/wiki/Q232024#P69"}},{"key":"awards","label":"Awards","values":[{"text":"Fellow of the Royal Society of Edinburgh","wikidata":"https://www.wikidata.org/wiki/Q5438598","date":"1932"},{"text":"Nobel Prize in Physiology or Medicine","wikidata":"https://www.wikidata.org/wiki/Q80061","date":"1923"},{"text":"Canadian Medical Hall of Fame","wikidata":"https://www.wikidata.org/wiki/Q3517661","date":"2012"},{"text":"Cameron Prize of the University of Edinburgh","wikidata":"https://www.wikidata.org/wiki/Q29026864"},{"text":"Fellow of the Royal Society","wikidata":"https://www.wikidata.org/wiki/Q15631401","date":"1923"}],"source":{"label":"Wikidata","url":"https://www.wikidata.org/wiki/Q232024#P166"}}],"office":null,"sections":[],"cited":[],"cited_from":null,"videos":[],"last_reviewed":null,"organizations":[],"same_as":["https://en.wikipedia.org/wiki/John_Macleod_(physiologist)","https://www.wikidata.org/wiki/Q232024"],"faq":[{"q":"When was John Macleod born?","a":"John Macleod was born on 6 September 1876 in Clunie."},{"q":"Where did John Macleod study?","a":"John Macleod was educated at University of Aberdeen, University of Aberdeen School of Medicine."}],"related":[{"name":"Aaron Klug","url":"https://diginpl.com/people/aaron-klug"},{"name":"Alan Hodgkin","url":"https://diginpl.com/people/alan-hodgkin"},{"name":"Andre Geim","url":"https://diginpl.com/people/andre-geim"},{"name":"Andrew Huxley","url":"https://diginpl.com/people/andrew-huxley"},{"name":"Antony Hewish","url":"https://diginpl.com/people/antony-hewish"},{"name":"Archer Martin","url":"https://diginpl.com/people/archer-martin"},{"name":"Arthur Harden","url":"https://diginpl.com/people/arthur-harden"},{"name":"Brian Josephson","url":"https://diginpl.com/people/brian-josephson"},{"name":"C.
