Daniel Carter "Uncle Dan" Beard (June 21, 1850 - June 11, 1941) was an American illustrator, author, youth leader, and social reformer who founded the Sons of Daniel Boone in 1905, which Beard later merged with the Boy Scouts of America (BSA). He started an early career as an engineer and surveyor. He attended art school in New York City. He wrote a series of articles for St. Nicholas Magazine that later formed the basis for The American Boy's Handy Book. He was a member of the Student Art League, where he met and befriended Ernest Thompson Seton in 1883. He illustrated a number of books for Mark Twain, and for other authors such as Ernest Crosby.
