Edward Mellanby

Sir Edward Mellanby, GBE, KCB, MD, FRCP, FRS (8 April 1884 – 30 January 1955)^{[1][2][3][4][5][6][7][8]} discovered vitamin D and the role of the vitamin in preventing rickets in 1919^[9].

He was born in West Hartlepool, the son of a shipyard owner, and educated at Barnard Castle School and Emmanuel College, Cambridge, where he studied physiology.

After working as a research student from 1905 to 1907, he studied medicine at St. Thomas's Hospital in London, and in 1913 became a medical doctor. He served as a lecturer at King's College for Women in London from 1913 to 1920, during which time he was asked to investigate the cause of rickets. He discovered that feeding caged dogs on a diet of porridge induced rickets, which could then be cured with cod liver oil and concluded that rickets was caused by a dietary factor. It was later discovered that the actual cause of rickets is lack of vitamin D due to lack of sunlight which can be prevented or remedied by ingesting food rich in vitamin D.

In 1920 he was appointed professor of pharmacology at the University of Sheffield, and consultant physician at the Royal Infirmary in that city. He then served as the secretary of the Medical Research Council from 1933 to 1949.

He was elected a Fellow of the Royal Society in 1925. ^[10][11] He was awarded their Royal Medal in 1932 and their Buchanan Medal in 1947.

He delivered the Croonian Lecture to the Royal College of Physicians in 1933 and the Croonian lecture to the Royal Society in 1943, both on the subject of diet.

He was knighted (KCB) in 1937 and made GBE in 1948.

Publications include Nutrition and Disease - the Interaction of Clinical and Experimental Work (Edinburgh and London: Oliver and Boyd, 1934). In the work, he writes extensively on vitamin deficiency. He delivered the Harveian Oration to the Royal College of Physicians in 1938.
