Also known as Sealth, Seathle, Seathl, or See-ahth, Chief Seattle was a Duwamish chief. A prominent figure among his people, he pursued a path of accommodation to white settlers and the city of Seattle was named after him. A widely publicized speech arguing in favor of ecological responsibility and respect of native Americans' land rights has been attributed to him. He was baptized in the Roman Catholic Church, and given the baptismal name Noah, probably in 1848 near Olympia. He died June 7, 1866 and his grave site is at the Suquamish Tribal Cemetery.
