The Sons of Daniel Boone (sometimes called the Society of the Sons of Daniel Boone), later the Boy Pioneers of America, was a youth program developed by Daniel Carter Beard in 1905 based on the American frontiersman. When Dan Beard joined the Boy Scouts of America (BSA) in 1910 as one of their national Scout commissioners, he merged his group into the fledgling BSA. Boys were organized into groups called forts. The officers of the fort took on names of frontiersmen and had specific insignia: A handbook for the program wasn't published until 1909, as Boy Pioneers: Sons of Daniel Boone.
