P. T. Barnum was the owner of a circus known as "The Greatest Show on Earth". The Fourth Doctor and Sarah Jane Smith visited his circus in 1885. Their presence inadvertently led to the death of Jumbo the Elephant. (AUDIO: The Wondrous Box)

Henry Gordon Jago once compared Mr Wednesday to Barnum. (AUDIO: The Backwards Men)

Barnum was played by Roger Ashton-Griffiths in the film Gangs of New York.
