Emmett Kelly was a gifted entertainer who gained world fame as the hobo clown, "Weary Willie." In 1933, while working with the Hagenback-Wallace Circus, his "Weary Willie" character was born and instantly became a symbol of hope for those hard hit by the depression. Kelly found his true home in 1941 when he joined the Ringling Brothers and Barnum and Bailey Circus. He became a major star of the circus and even made appearances in films, night clubs, television, and on the Broadway stage. He was inducted into the Clown Hall of Fame in 1989.
In 1956 he retired from regular circus work, though he continued to work sporadically. He was a mascot in spring training for the Brooklyn Dodgers in 1957. He also made several appearances on television after his retirement.
