Charles Stuart Nimmo (10 June 1895 — 20 February 1943) was a Scottish international rugby union player.
Born in Edinburgh, Nimmo attended Viewpark School and George Watson's College. He enlisted with the 9th Royal Scots at the beginning of World War I and was commissioned into the Seaforth Highlanders in November, 1914.[1]
Nimmo gained his solitary Scotland cap as a half-back in the 1920 Calcutta Cup match against England at Twickenham, replacing an injured Jake Selby in the line up. He played his club rugby with Selby for Watsonian XV and was captain during their championship-winning 1920–21 season.[2]
A 1921 University of Edinburgh graduate, Nimmo obtained a medical degree and after a short appointment at Edinburgh Royal Infirmary became a general practitioner in Jedburgh in 1922.[3]
