Jay North
Jay Waverly North is an American actor. Beginning a prolific career as a child actor at the age of six, he became a household name during the early 1960s for his role as the wellmeaning but mischievous Dennis Mitchell on the CBS situation comedy Dennis the Menace, based on the comic strip created by Hank Ketcham.
North was born at Cedars of Lebanon Hospital in Hollywood, California, the only child of Jay and Dorothy North. Norths father was an alcoholic, and his parents marriage was stormy. When he was four, his parents separated, and North never saw his father again. As a single mother, Mrs. North went to work as the secretary to the West Coast director of AFTRA to support herself and Jay.
