Daniel Rutherford
The son of Professor John Rutherford (1695–1779) and his wife, Anne Mackay, Daniel Rutherford was born in Edinburgh on 3 November 1749. He began college at the age of 16 at Mundell's School on the West Bow close to his family home, and then studied medicine under William Cullen and Joseph Black at the University of Edinburgh, graduating with a doctorate (MD) in 1772. From 1775 to 1786 he practiced as a physician in Edinburgh.
Margaret Rutherford
In the 1950s, Rutherford and Davis unofficially adopted the writer Gordon Langley Hall, then in his 20s. Hall later had gender reassignment surgery and became Dawn Langley Simmons, under which name she wrote a biography of Rutherford in 1983.
