Dan Rice , was an American entertainer of many talents, most famously as a clown, who was pre-eminent before the American Civil War. During the height of his career, Rice was more of a household name than Abraham Lincoln or Mark Twain. Coining the terms "One Horse Show" and "Greatest Show", he was a leading personality in the new American "pop culture", brought on by the technological changes of the Industrial Revolution and resultant mass culture. Rice became so popular he ran for President of the United States in 1868. With changes in circus venues and popular culture after the Civil War, his legendary talents under the big top have gradually slipped into almost total historical obscurity such that in 2001, biographer David Carlyon called him "the most famous man you've never heard of".
