Lloyd Stowell Shapley (born June 2, 1923) is an American game designer who is better known as a distinguished mathematician and economist. In 1943, as a student at Harvard he was drafted and as a sergeant in the Army Air Corps in Chengdu, China, he received the Bronze Star decoration for breaking the Soviet weather code.
He was the son of astronomer Harlow Shapley (1885–1972), the first person to realize that the Milky Way Galaxy was much larger than previously believed and that the Sun's place in the galaxy was in a nondescript location.
