James Irving Crump wrote in Og, Son of Og,"Dan Beard ... furnished the inspiration that made me interested in writing for boys and ultimately becoming the editor of Boys' Life, in which position I served for twenty-five years."He is most famous for his prehistoric boy series - Og, Son of Fire (1922), Og, Boy of Battle (1925), Og of the Cave People (1935) and Og, Son of Og (1965), spanning over 40 years. While most of the stories first appeared in Boys' Life, some of the Boys' Life stories never made it into the books. He also wrote an "American prehistoric" - Mog, the Mound Builder (1931), and numerous other books and articles, mainly for young people. Og, Son of Fire became a popular radio show in 1934-35.
