General Ely Samuel Parker (1828-95), a Seneca Indian, was the grandson of Red Jacket. Like his ancestor, he vowed from an early age to succeed in both the white and Indian worlds. He became grand sachem in the Iroquois Confederacy in 1852. When he was eighteen, Parker joined the U.S. army and rose to the rank of brevet brigadier general. During the Civil War, he was Grant's military secretary, and it was Parker who transcribed Grant's terms for General Lee's surrender at Appomattox. For his efforts during the war, Parker was made commissioner of the Bureau of Indian Affairs, the first Native American to hold the position. While holding that office, he called for the end of the treaty system in order to give Indians a better advantage during negotiations.
