About Ernest Thompson Seton
Ernest Thompson Seton was a Canadian and American author, wildlife artist, founder of the Woodcraft Indians in 1902, and one of the founding pioneers of the Boy Scouts of America (BSA) in 1910. Baden-Powell went on to found the Scouting movement worldwide and Seton became the president of the committee that founded the Boy Scouts of America (BSA) and was its first (and only) Chief Scout. He attended the Ontario College of Art in 1879, studying with John Colin Forbes, then won a scholarship in art to the Royal Academy in London, England in 1880. British by birth, Seton was not naturalized as Canadian (as status did not legally exist until 1947; he thus remained a British subject) and became an American in 1931.
