According to Wikipedia: "Andy Adams (May 3, 1859 – September 26, 1935) was an American writer of western fiction. Andy Adams was born in Indiana. His parents, Andrew and Elizabeth (Elliott) Adams, were pioneers. As a boy he helped with the cattle and horses on the family farm. In the early 1880s he went to Texas, where he stayed for 10 years, spending much of that time driving cattle on the western trail. In 1890 he left the trail to try his hand at business, but the venture failed, so he turned his hand to gold-mining in Colorado and Nevada. In 1894, he settled in Colorado Springs, where he lived until his death. He began writing at the age of 43, publishing his most successful book, The Log of a Cowboy, in 1903. His other works include A Texas Matchmaker (1904), The Outlet (1905), Cattle Brands (1906), Reed Anthony, Cowman: An Autobiography (1907), Wells Brothers (1911), and The Ranch on the Beaver (1927)."
