William Oliver Wallace (8 December 1929 – 8 March 2009), known by his stage name Ali Bongo, was a British comedy magician and former president of The Magic Circle, who performed an act in which he was known as the "Shriek of Araby".

Young William spent his early years on a British station in Trimulgherry, Secunderabad, before going to Britain with his mother Lillian at the age of seven.

"[3] Among his later magic catchphrases were "Uju Buju Suck Another Juju", "Aldy Bority Phostico Formio", and "Hocus Pocus Fishbones Chokus".

His well-known ability for devising tricks and illusions and solving magical problems inspired the TV writer David Renwick to create a character who was a magician's assistant and amateur sleuth in the series Jonathan Creek.

He was subsequently returned to the United Kingdom and cared for in St Thomas's Hospital, London, where he later died from complications arising from pneumonia on 8 March.
