What did June Lockhart pass from?
Natural causes confirmed by family
- A family representative, Lyle Gregory, told AP News (wire service) that Lockhart died of natural causes.
- CBS News (U.S. news outlet) and NPR (public broadcaster) both reported natural causes at her Santa Monica residence.
- Rolling Stone (culture magazine) and Deadline (entertainment trade) confirmed the same details independently.
Age and location at time of death
- Lockhart was 100 years old when she died at her home in Santa Monica, California.
- Her daughter June Elizabeth and granddaughter Christianna were by her side, according to Los Angeles Times (California newspaper).
- Reuters (global news agency) reported the death on Thursday, October 23, 2025.
The unanimous chorus from wire services, major newspapers, and trade outlets means the cause and timing are as verified as any celebrity death can be. For readers wondering “Is June Lockhart still alive?” — the answer is a clear no, and the reason is natural causes at an extraordinary age.
The implication: June Lockhart’s death, while peaceful, underscores the importance of corroborated reporting in an era of misinformation.
Who was the original mother on Lassie?
June Lockhart played Ruth Martin from 1958 to 1964
- When the show Lassie shifted from a farm setting to a suburban one, Lockhart stepped in as Ruth Martin, the first actress to play the mother in the new format.
- CBS News (U.S. news outlet) described her as “the actor best known for her role as the matriarch in Lassie.”
- AP News (wire service) called her a “maternal figure for countless television audiences.”
Character role and episode count
- Lockhart appeared in 186 episodes of Lassie over six seasons, cementing her as the definitive TV mom of that era.
- The role made her a household name and led to her next iconic part: Maureen Robinson in Lost in Space (1965–1968).
- The Guardian (British newspaper) noted that she “began her career in film before becoming especially associated with television.”
Did June Lockhart play on Bewitched?

- She played a character named Mrs. Fritch / a mother.
- Rolling Stone (culture magazine) confirmed the appearance.
Lockhart’s gift was making maternal authority feel effortless — on screen she was steady, off screen she was disciplined. That discipline, as Times of India (lifestyle outlet) explored, likely contributed to her reaching 100 without major health issues.
The pattern: Lockhart’s ability to project warmth without sentimentality made her the matriarch audiences trusted on three different classic shows.
