‘Leave It to Beaver’ Star John Eimen Passes Away at 76 – Cause of Death Revealed

John Eimen, the former child actor known for roles in beloved TV series such as Leave It to Beaver, McKeever and the Colonel, and The Twilight Zone, has died at 76.

He passed away at his home in Mukilteo, Washington, on Friday, following a recent diagnosis of prostate cancer in September. His family confirmed his death.

Eimen began his career in entertainment when he was very young. He was born in Chicago on October 2, 1949, and a talent scout found him while visiting his first-grade class in the Los Angeles area, thanks to a connection with his teacher.

He started his television career at just six years old, appearing as a schoolmate of Theodore Cleaver (played by Jerry Mathers) in the premiere episode of Leave It to Beaver in 1957. He continued to appear in several more episodes of the popular show, which aired for six seasons until 1963.

In 1961, Eimen landed the role of Tommy in a planned TV show called Dr. Kate, which would have starred Jane Wyman, an actress who had already won an Academy Award. As Eimen remembered, getting cast as her son in the show’s first episode felt like a major opportunity.

The show had strong potential for a long run because it initially secured a sponsor. Unfortunately, the sponsor withdrew their support, stating they were unhappy with the planned late-night timeslot. Despite the series not being picked up, the pilot episode did air in 1960 as part of CBS’ Westinghouse Desilu Playhouse, and the creator occasionally continued to receive small royalty payments for it.

Following her role in Dr. Kate, Eimen appeared in the 1962 NBC comedy McKeever and the Colonel, where she played Cadet Monk Roberts, a student at a military academy. Though the show featured Scott Lane and Allyn Joslyn, it was short-lived, running for just 26 episodes.

In 1962, he also appeared in an episode of The Twilight Zone called “The Fugitive,” and continued to be a guest star on many popular television shows like Bachelor Father, The Rebel, Have Gun – Will Travel, Wagon Train, The Untouchables, and Lawman.

Eimen was also featured in Carnation advertisements that appeared in magazines and newspapers, often sporting a milk mustache. He acted in several films, including the 1965 movie Never Too Late starring Connie Stevens, and his final television appearance was in a 1967 episode of Petticoat Junction.
