Eimen began his acting career remarkably young, discovered by a talent agent who knew his first-grade teacher in the Los Angeles area. His breakthrough came in October 1957, when he appeared as a classmate of Theodore Cleaver (Jerry Mathers) on the very first episode of CBS’ Leave It to Beaver. He returned for additional episodes throughout the show’s six-season run that ended in 1963.
The red-haired, freckle-faced performer quickly became a familiar face on television during the 1950s and early 1960s. Beyond Leave It to Beaver, Eimen landed roles on prestigious shows including Have Gun — Will Travel, The Untouchables, The Rebel, Wagon Train, and Lawman. In 1962, he appeared on a memorable Twilight Zone episode titled “The Fugitive,” showcasing his range as a young actor.
The Role That Defined His Career: Cadet Monk Roberts

While Eimen appeared in dozens of television productions, his signature role came when he was cast as Cadet Monk Roberts on the 1962-63 NBC sitcom McKeever and the Colonel, which starred Scott Lane and Allyn Joslyn as the title characters. Though the series ran only 26 episodes, Eimen’s portrayal of the military school cadet left a lasting impression on viewers of the era.
Before landing this starring role, Eimen had been chosen to play Tommy, the son of Academy Award-winning actress Jane Wyman, in a proposed TV drama called Dr. Kate from Desilu Productions. Though Wyman eventually backed out due to dissatisfaction with the scheduling, the pilot aired as a 1960 episode of CBS’ Westinghouse Desilu Playhouse. Remarkably, Eimen continued to receive small residual checks from that episode years later.
