Black was born in Chicago, Illinois, to Jill and Robert Schwartz - a store owner and an executive, respectively.[1] He grew up in Hillsborough Township, New Jersey,[2] where he attended Hillsborough High School. His parents divorced when he was three years old. His mother, Jill, came out as a lesbian.[3] When he was twelve, his father had neurological surgery following a mysterious assault. Days after being released from the hospital he was re-admitted for an infection and died as a result of an allergic reaction to an administered medication. His birth name, Schwartz, is derived from the German word "schwarz," which has the same meaning as his stage name, Black. Schwartz changed his name to Michael Ian Black to avoid confusion with the actor Mike Schwartz.[4]
Black attended Stagedoor Manor Performing Arts Training Center in New York and Tisch School of the Arts at New York University, but later dropped out.
