Hopalong Cassidy or Hop-along Cassidy is a fictional cowboy hero created in 1904 by the author Clarence E. Mulford, who wrote a series of popular short stories and many novels based on the character.
In his early writings, Mulford portrayed the character as rude, dangerous, and rough-talking. He had a wooden leg which caused him to walk with a little "hop", hence the nickname. From 1935, the character—as played by movie actor William Boyd in films adapted from Mulford's books—was transformed into a clean-cut, sarsaparilla-drinking hero. Sixty-six popular films appeared, only a few of which were loosely based on Mulford's stories.
