P.T. Barnum

Answer: P.T. Barnum was a successful promoter who founded what became the Ringling Bros. and Barnum & Bailey Circus in 1871.

Although Barnum was also an author, publisher, philanthropist, and for some time a politician, he said of himself, “I am a showman by profession…and all the gilding shall make nothing else of me”. Thanks in part to the enduring success of his circus, Barnum is celebrated as a brilliant promoter and a showman who transformed the nature of commercial entertainment in the 19th century. Barnum’s story made it to the big screen in The Greatest Showman, with Hugh Jackman in the starring role.
