CORNPLANTER (1732-1836), an American Indian chief of the Seneca tribe, was born in Conewaugus, on the Genesee river, in New York, in 1732, the half-breed son of John O'Bail, an Indian trader. In alliance with the French against the English, Cornplanter became the leader of a war-party of the Senecas, and was present at Braddock's defeat near Ft. Duquesne in 1755. Dur ing the Revolutionary War he participated in the destruction of frontier settlements in New York and in the valley of Wyoming in Pennsylvania, but later displayed a genuine friendship for the white people. For many years Cornplanter and his able associate, Red Jacket (q.v.), were the most influential counsellors of their people. Cornplanter is said to have been one of the first temper ance lecturers in America. He died on the Seneca reservation, on Feb. 13, 1836.
