June Lockhart, a popular actress of the 1950s and ’60s known for her roles in “Lost In Space,” “Lassie” and “Meet Me in St. Louis,” died of natural causes on Oct. 23 in Santa Monica, Calif. She was 100.
Lockhart became known for her performances as Timmy’s foster mother, Ruth Martin, on the CBS series “Lassie” from 1958 to 1964. She took over from Cloris Leachman as the Martin family moved on to the famous collie’s farm and became foster parents to both the orphaned Timmy and Lassie.
She then starred as Dr. Maureen Robinson on the CBS series “Lost in Space” from 1965 to 1968. She played a brilliant biochemist and loving mother of three who is marooned in space along with her family.
“When I wasn’t shooting Lassie, I became the mistress of Scrabble with my hairdresser and the crew,” she told Closer magazine in 2024. She also noted that “Lost in Space” was her favorite project. “It was so campy,” she said, “And I truly enjoyed my relationship with my space family.”
Over nearly eight decades on screen, Lockhart went on to appear in dozens of series and movies well into her 80s, with recurring roles on “Petticoat Junction,” “General Hospital” “Beverly Hills 90210,” and guest appearances on shows from “The Beverly Hillbillies” to “Happy Days” to “Full House, “Roseanne” and “Gray’s Anatomy.”
The daughter of actor Gene Lockhart and actress Kathleen Lockhart, she was born in New York City in 1925. She made her feature film debut at 13 years old, starring alongside both of her parents in Edwin L. Marin’s 1939 “A Christmas Carol,” where she played Belinda Cratchit. After her breakout role, she appeared in films such as “All This, and Heaven Too,” “Meet Me in St. Louis,” “The Yearling,” and “Sergeant York.”
Prior to the TV series, Lockhart appeared in the feature “Son of Lassie” as Priscilla, the Duke of Rudling’s granddaughter. In the 1950s, Lockhart guest-starred in several Western series such as “Wagon Train,” “Cimarron City,” “Gunsmoke,” “Have Gun – Will Travel,” and “Rawhide.”
She was nominated for two Emmys, including Best Actress in a Leading Role in a Dramatic Series for her performance in “Lassie.” She also received two stars on the Hollywood Walk of Fame, one for motion pictures and one for television. Lockhart was previously the recipient of a Special Tony Award for Outstanding Performance by a Newcomer for her role on Broadway in “For Love or Money” in 1948.
A private service has been planned in her honor. Instead of sending flowers, Lockhart’s family suggests donating to The Actors Fund, ProPublica and International Hearing Dog, Inc.
Laaaaaaaaaaaas-sie!
RIP June.
A successful and full life!
Lost in Space is some of my earliest tv memories and I attribute it to my life long interest in Sci-Fi movies.
100 is a full life.
Thank you Ma’am for your wholesome contributions to a time when tv was actually a family affair.
RIP 🙏
AND——NO SCANDALS !!!!!
Hated Timmy. Jeff was way better. Liked Timmy’s mom. I guess Jeff got too old for the show. Gramps was pretty cool too.
One for the “Wow, I wouldn’t have guessed that they were still alive” file.
But RIP, June. Loved those “Lost in Space” reruns in the ‘70s.
RIP
Sad!
The family slipped in donating to radical ProPublica.
“Meet Me in Saint Louis” is one of my all-time favorite movies. RIP June.
RIP
I liked Jeff better too. I agree, he was probably aging out of the role.
God speed dear
A favorite of this 1950’s baby, RIP June. 😓
All that stress from Dr. Smith probably shaved a few years off her life, but 100 is still good
A true movie and TV icon. RIP June, you will indeed be missed.
I was a little kid in the early 60s - close to Timmy’s age in the Lassie show. I loved that show and June Lockhart was a sweet motherly figure kind of like my mother.
