Lou Jacobs was an auguste clown who performed for Ringling Bros. and Barnum & Bailey Circus for more than 60 years. He was inducted into the International Clown Hall of Fame in 1989. He is credited with popularizing the clown car, which has been a staple of circus clown acts ever since. He is also often cited as the originator of the red rubber ball nose, which is used by many clowns today. He was the first living person to have his portrait appear on an American postage stamp.
