Oscar Zoroaster Phadrig Isaac Norman Henkle Emmannuel Ambroise Diggs (also known as the "Wizard of Oz" and, during his reign, as "Oz the Great and Terrible" or the "Great and Powerful Oz") is a fictional character in the Land of Oz created by American author L. Frank Baum. The character was further popularized by a stage play and several films, including the classic 1939 film and the 2013 prequel adaptation.
He is not a real wizard but an ordinary man from Omaha, Nebraska who was accidentally sent to Oz in a hot air balloon in a terrible storm while performing at the carnival. When he landed in Oz, the people thought he was a great wizard and gave him a job as their local sorcerer. His Kansas counterpart is a touring fortune teller named Professor Chester Marvel who had a horse named Sylvester.
