Ernest Thompson SetonBorn 14 Aug 1860; died 23 Oct 1946 at age 86. English-American naturalist, author and illustrator who applied these skills in over forty books on wild life, woodcraft, Indian lore and animal-fiction stories. As a capable naturalist, in his field observations he made detailed studies of morphology, physiology, distribution, and behaviour. His fame as author began with Wild Animals I Have Known (1898) - still in print a century later. Over a period of twenty years he delivered over three thousand lectures. Believing in promoting the values of ethology and ecology, he was chairman of the committee that established the Boy Scouts in the U.S. (1910). Seton envisioned the North American Indian as a model for the movement, but Baden-Powell's military structure was adopted as in Britain.«
