Hopalong Cassidy is a cowboy hero, created in 1904 by Clarence E. Mulford, who wrote a series of popular stories and twenty-eight novels.
In his early print appearances, the character was a rude, dangerous and rough-talking "galoot". Beginning in 1935, the character, played by William Boyd, was transformed into the clean-cut hero of a series of 66 immensely popular films, only a few of which relied on Mulford's works. Mulford rewrote his earlier stories to fit the movie conception; these led in turn to a the comic book series modeled after the films.
