Mulford (1883-1956) was a prolific author whose short stories and 28 novels were adapted to radio, feature film, television, and comic books, often deviating significantly from the original stories, especially in the character's traits. Many of his stories depicted Cassidy and other men of the Bar-20 ranch. But more than just writing a very popular series of Westerns, Mulford recreated an entire detailed and authentic world filled with characters drawn from his extensive library research.
