His career spanned more than forty years, and his stories, poems, and articles were published in more than 225 magazines. His work appeared alongside that of his contemporaries, including Mark Twain, Sax Rohmer, James B. Hendryx, Berton Braley, F. Scott Fitzgerald, Don Marquis, Will Rogers, and Edgar Rice Burroughs. Despite the enormous volume of his work, Butler was, for most of his life, only a part-time author. He worked full-time as a banker and was very active in his local community. A founding member of both the Dutch Treat Club and the Authors League of America, Butler was an always-present force in the New York City literary scene.
