Chief Seattle (an Anglicization of Si’ahl), ((Lushootseed pronunciation: [siʔaɬ], (c. 1780 – June 7, 1866), was a Dkhw’Duw’Absh (Duwamish) chief, also known as Sealth, Seathle, Seathl, or See-ahth, and a leader of the Suquamish and Duwamish Native American tribes in what is now the U.S. state of Washington. A prominent figure among his people, he pursued a path of accommodation to white settlers, forming a personal relationship with David Swinson “Doc” Maynard. Seattle, Washington 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; however there is controversy about what, if anything, he actually said. – Wikipedia
