Oscar Diggs

Oscar Diggs is a fictitious character from L. Frank Baum's timeless children's classic The Wonderful Wizard of Oz. An old circus performer and a ventriloquist, Diggs took off in a hot air balloon which he was not skilled in operating, and ended up in the land of Oz. When the people of the City of Emeralds saw him drift down out of the sky, they assumed he must be a Wizard.

A fast-talking salesman, con-artist and amateur illusionist, Diggs knew his only chance to avoid the wrath of the two wicked witches was to build an illusion around himself, the mysterious Wizard of Oz. When Dorothy and her friends discover his secret, Diggs agrees to help them on the condition that they won't out him as a fraud to the people of Oz. In the end he accidentally flies away in a hot air balloon meant to transport Dorothy back to Kansas.

Diggs named the Scarecrow of Oz as his successor before he left.
