John Yocum Randolph Crawford[1] (August 4, 1915 – February 14, 1976) was an American bridge and backgammon player.
In bridge, he was a member of United States teams that won the first three Bermuda Bowls, or world teams championships, in 1950, 1951 and 1953; a wholly new team represented the US in 1954.
In backgammon, Crawford is known as the inventor of the "Crawford rule", a regulation that restricts use of the doubling die in match play.
Of Scots descent, the younger son of Andrew Wright Crawford Sr. (1873–1929), a town planner, he was born at Bryn Mawr, Pennsylvania, and died in Manhattan aged 60.
He was married to Carol Stolkin, née Ross, also a celebrated backgammon player.
