John George Macleod

In 1964, Macleod wrote the medical handbook Clinical Examination (later renamed Macleod's Clinical Examination), which is still (in 2017) in print in its 13th Edition and has sold close to a million copies. In 1964, the physician Sir Stanley Davidson offered him the opportunity to update Davidson's Principles and Practice of Medicine, which sold more than two million copies worldwide and of which Macleod contributed to six editions. These two textbooks played a crucial part in keeping Edinburgh on the world map of medicine and were translated into many languages such as Japanese and Russian. In 1971, he was appointed vice-chairman of the University Department of Medicine of the Western General Hospital. He died in Edinburgh in April 2006, aged 90.

On 21 December 1942, John George Macleod married Nancie Elizabeth Clark. Their issue are two sons, Peter and Keith and a daughter, Gillian.

Macleod was educated at George Watson's College and studied medicine at the University of Edinburgh, where he graduated in 1938. During the Second World War, from 1939 to 1945, he was a major in the army at the Royal Army Medical Corps. In 1941, he obtained a post at the University of Edinburgh and, in 1947, was asked to become a member of the Royal College of Physicians of Edinburgh. In 1950, he became a consultant physician at Edinburgh's Western General Hospital.
