This article is about the historic elephant. For other uses, see Jumbo (disambiguation). Jumbo (about Christmas 1860 â September 15, 1885), also known as Jumbo the Elephant and Jumbo the Circus Elephant, was a 19th-century male African bush elephant born in the Sudan. Jumbo was eventually exported to Jardin des Plantes, a zoo in Paris, France; and then transferred in 1865 to London Zoo in England. Jumbo was sold to P. T. Barnum, who took him to America for exhibition in March 1882. The giant elephant's name has spawned the common word, jumbo, meaning large in size.
