Jumbo (December 25, 1860 – September 15, 1885), also known as Jumbo the Elephant and Jumbo the Circus Elephant, was a 19th-century male African bush elephant born in Sudan. Jumbo was exported to Jardin des Plantes, a zoo in Paris, and then transferred in 1865 to London Zoo in England. Despite public protest, Jumbo was sold to P. T. Barnum, who took him to the United States for exhibition in March 1882.

The elephant’s name spawned the common word “jumbo”, meaning large in size. Examples of his lexical impact are phrases like “jumbo jet”, “jumbo shrimp”, “jumbo eggs”, and “jumbotron”. Jumbo’s shoulder height has been estimated to have been 3.23 metres (10 ft 7 in) at the time of his death, and was claimed to be about 4 m (13 ft 1 in) by Barnum.

While in London, Jumbo broke both tusks, and when they regrew, he ground them down against the stonework of his enclosure. His keeper in London was Matthew Scott, whose 1885 autobiography details his life with Jumbo.

“Jumbo’s pitiful refusal to leave London Zoo tugged at the nation’s heartstrings” In 1882, Abraham Bartlett, superintendent of the London zoo, sparked national controversy with his decision to sell Jumbo to the American entertainer Phineas T. Barnum of the Barnum & Bailey Circus for £2,000 (US$10,000). This decision came as a result of concern surrounding Jumbo’s growing aggression and potential to cause a public disaster. The sale of Jumbo, however, sent the citizens of London into a panic, because they viewed the transaction as an enormous loss for the British empire. 100,000 school children wrote to Queen Victoria begging her not to sell the elephant.
