Craige Schensted, who formally changed his name to Ea Ea, was an American physicist and mathematician who first formulated the insertion algorithm that defines the Robinson–Schensted correspondence. Under a different form, that correspondence had earlier been described by Gilbert de Beauregard Robinson in 1938, but it is due to the Schensted insertion algorithm that the correspondence has become widely known in combinatorics. Schensted also designed several board games including *Star, Star, and Y.
