How did Eminem get his name?

Eminem was born Marshall Bruce Mathers III.

At age 14, Eminem began rapping with high school friend, Mike Ruby. They adopted the names "Manix" and "M&M", the latter of which evolved into "Eminem" (often stylized as EMINƎM).

Eminem also uses alter egos in his songs for different rapping styles and subject matter. His best-known alter ego, Slim Shady, first appeared on the Slim Shady EP. In this persona, his songs are violent and dark, with a comic twist.
