At 17, he joined the Fred Karno troupe,and from 1910 to 1912, he toured the U.S. It was in November 1913, during a second tour of the U.S., that he got his big break. Movie producer Mack Sennett signed him to his Keystone Company for a salary of $150 per week. Soon after Chaplin's first movie (Making a Living), he developed the character known as the "Little Tramp." With his bowler hat, cane, baggy pants, and large shoes, many think that Chaplin created this character from his memory of the desperate poverty of his childhood. In just one year, Chaplin made 35 movies with Keystone, and his "Little Tramp" character became world-famous.
