In 1907, Robert Baden-Powell founded the Scouting movement in England using elements of Seton's works among other influences. In 1909, Chicago publisher W. D. Boyce was visiting London, where he encountered a boy who came to be known as the Unknown Scout. Boyce was lost on a foggy street when an unknown Scout came to his aid, guiding him to his destination. The boy then refused Boyce's tip, explaining that he was a Boy Scout and was merely doing his daily good turn. Interested in the Boy Scouts, Boyce met with staff at the Boy Scouts Headquarters and, by some accounts, Baden-Powell. Upon his return to the US, Boyce was inspired by his experience and incorporated the "Boy Scouts of America" on February 8, 1910. Edgar M. Robinson and Lee F. Hanmer became interested in the nascent BSA and convinced Boyce to turn the program over to the YMCA for development in April 1910. Robinson enlisted Seton, Beard, Charles Eastman, and other prominent leaders in the early youth movements. Former president Theodore Roosevelt, who had long complained of the decline in American manhood, became an ardent supporter. In January 1911, Robinson turned the movement over to James E. West who became the first Chief Scout Executive and Scouting began to expand in the US Among other programs in the US, the Woodcraft Indians and Sons of Daniel Boone, eventually merged with the BSA.
