Hopalong Cassidy was created by Clarence E. Mulford in 1904. Mulford wrote twenty-eight novels and also stories involving his character. The name was derived from the famous outlaw Butch Cassidy who was in the news at the time. This original character of Hopalong Cassidy was that of a rough-talking and dangerous man of the range.
In 1935, the film Hop-Along Cassidy was released, starring William Boyd. The character of Hopalong had been given a makeover and he was now portrayed as a clean-cut hero. This was the first of 66 very popular films, that established the character as we know him today and spawned a large merchandising industry.
Hopalong Cassidy became the first Western television series airing on June 24, 1949. During this time Clarence Mulford rewrote some of his earlier stories to fit this new image of Hopalong and these led onto his appearance in comic books. In January 1950 Dan Spiegel began drawing a syndicated comic strip that lasted until 1955.
