The Little Tramp, the enduring, mustachioed character brought to life by Charlie Chaplin, is celebrating one heck of a birthday this year: 100. The character first appeared in a Keystone comedy short called “Kid Auto Races at Venice” in 1914, where he plays a bumbling spectator constantly getting in the way of the camera’s attempts to focus on the action. Another film, “Mabel Behind the Wheel,” was technically the first Tramp film shot, but “Kid Auto Races” was released first, so it gets the permanent claim to fame. Of course, this being 1914, that difference is only a matter of days, so it’s really only a distinction for the record books. Both films are very charming and recognizably set up the many iterations of the character that were to follow–and not just in costume, but the Tramp’s personality that we’d come to know as well.
