LAKE BUTLER, Fla. (AP) — Jay North, who starred as the towheaded mischief maker on TV’s “Dennis the Menace” for four seasons starting in 1959, has died. He was 73.

North died Sunday at his home in Lake Butler, Florida, after battling colon cancer, said Laurie Jacobson, a longtime friend, and Bonnie Vent, who was his booking agent.

“He had a heart as big as a mountain, loved his friends deeply. He called us frequently and ended every conversation with ‘I love you with all my heart,’” Jacobson wrote in a tribute on Facebook.

North was 6 when he was cast as the smiling troublemaker in the CBS sitcom adaptation of Hank Ketcham’s popular comic strip that took place in an idyllic American suburb.

Often wearing a striped shirt and overalls, Dennis’ mischievous antics frequently frustrated his retired next-door neighbor George Wilson, played by Joseph Kearns. Dennis’ patient parents were played by Herbert Anderson and Gloria Henry.

The show ran on Sunday nights until it was canceled in 1963. After that it was a fixture for decades in syndication.

Later, North appeared on TV in shows including “The Man from U.N.C.L.E.,” “The Lucy Show,” “My Three Sons,” “Lassie” and “The Simpsons,” and in movies like “Maya” (1966), “The Teacher” (1974) and “Dickie Robert: Former Child Star” (2003).
