Peter McWilliam, Scottish-English footballer and manager (b. 1878)
Peter McWilliam (21 September 1879 – 1 October 1951) was a Scottish footballer who played at left-half for Inverness Thistle, Newcastle United and Scotland. He won every domestic trophy during his nine years with Newcastle United.
He went on to manage Tottenham Hotspur on two occasions as well as Middlesbrough. He was the longest serving manager at Tottenham (however, both his stints were interrupted by world wars, therefore he managed fewer years of normal football) and led Spurs to an FA Cup win in 1921, becoming the first man to win the competition as a player and a manager.
