June Lockhart Dies at 100: Inside the Lost in Space Legend’s Marriages and Children

Sad news to close out the week: June Lockhart, the TV icon from Lassie and Lost in Space, has died. She was 100. What a run.

The basics

Lockhart passed away on Thursday, Oct. 23, at 9:20 p.m. local time in Santa Monica, California. People reports the cause was natural causes. She was best known as Maureen Robinson on Lost in Space and as America’s favorite TV mom on Lassie, and she collected two Emmy nominations and a Tony Award along the way.

Side note because the internet is the internet: if you saw a stray line tying this to Diane Keaton, ignore it. Keaton is alive; that comparison floating around is just wrong.

Family snapshot

• 1951: Lockhart married former Navy physician Dr. John F. Maloney. They had two daughters: Anne Kathleen Lockhart (the actress many of you know as Anne Lockhart) and June Elizabeth Lockhart (often credited as Lizabeth), who opted for a lower profile while working in creative and production circles.
• 1959: That first marriage ended for reasons that were kept private.
• 1959: Later that year she married architect John Lindsay.
• October 1970: Lockhart and Lindsay divorced after about a decade together.
• After that: She did not remarry or step into any public relationships. She focused on work and on raising her daughters, and she often said those years taught her resilience, independence, and how to juggle motherhood with a very public career. She kept close ties with family and stayed on good terms with her exes.

The daughters

Anne Lockhart, born in 1953, followed her mom into the business and made her own mark as Lt. Sheba in Battlestar Galactica (1978-1979). She also turned up on Murder, She Wrote, Knight Rider, and Law & Order, and she has done voice work too — a pretty similar across-the-board versatility to her mother’s.

The younger daughter, June Elizabeth, chose a more private path and contributed behind the scenes, keeping the family’s creative streak going without stepping into the spotlight.

Why she mattered

From Lassie to a late-series turn on Petticoat Junction — and of course Lost in Space — Lockhart was a steady, familiar face in classic TV. She bridged film, television, and stage at a high level for decades, which is rarer than it sounds. Even stripped of the nostalgia, the resume holds up.

June Lockhart leaves behind a long career, a family that carried the torch in their own ways, and a TV legacy that still reruns in people’s heads. Rest easy, Maureen Robinson.
