What was the name of the character played by Boris Karloff in the 1932 version of the film, 'The Mummy'?

In 1921, an archaeological expedition led by Sir Joseph Whemple (Arthur Byron) finds the mummy of an ancient Egyptian high priest named Imhotep (Boris Karloff). When an inspection of the mummy by Whemple's friend Dr. Muller (Edward Van Sloan) reveals that the viscera were not removed, Muller deduces that although Imhotep had been wrapped like a traditional mummy, he had been buried alive. Also buried with Imhotep is a casket with a curse on it. Despite Muller's warning, Sir Joseph's assistant Ralph Norton (Bramwell Fletcher) opens it. He reads aloud an ancient life-giving scroll, the "Scroll of Thoth". Imhotep rises and escapes with the scroll. Norton is driven insane.

The screenplay by John L. Balderston was from a story by Nina Wilcox Putnam and Richard Schayer. Released by Universal Studios, the film stars Boris Karloff, Zita Johann, David Manners, Edward Van Sloan and Arthur Byron.
