June Lockhart, who passed away at the remarkable age of 100, started her career in movies, but gained fame after transitioning almost entirely to TV. Having been offered limited opportunities to shine in films from her debut as a child in 1938 until 1947, she excelled on TV in numerous beloved series, most notably in Lassie.
Portraying Ruth Martin on Lassie
Taking over from a previous star in 1958, Lockhart remained in the series until 1964. She played Ruth Martin, wed to agriculturalist Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose dog was the eponymous hero of the series.
Even with playing a mother figure, Lockhart adeptly avoided being overshadowed by the smart dog. She described the program as “a fairy tale about people on a farm in which the dog solves all the problems in 22 minutes, in time for the last advertisement”. After she left the series, Lockhart commented: “In six sexless years of playing a rural wife and parent, I was hardly ever allowed to peck my on-screen husband on the face.”
Featuring in Lost in Space
Lockhart went straight into a second hit, Lost in Space (1965-68), a partly comedic science fiction series targeted mostly at young audiences and inspired by The Swiss Family Robinson. Lockhart and her co-star portrayed Maureen and John Robinson, two scientists exploring distant planets. Lockhart had to spend the majority of her time deftly trying to navigate special effects. As the series continued, the narrative became less and less about this space clan and more about the boy and his friendship with a mechanical being, and the cowardly antagonist Dr Zachary Smith.
Start in Entertainment
Lockhart’s feature film first role, at the age of 13, had come as Belinda Cratchit in A Christmas Carol (1938). In the roles of her mother and father, Bob and Mrs Cratchit, were her actual parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canadian-born Gene were both performers in dozens of films, as well as on theater, it was almost inevitable that June, who was born in New York, would enter show business.
Her first stage appearance, at the tender age of six, came in a non-singing role in an opera at the Metropolitan Opera in New York (1931).
Cinema Work
When her father was given a deal by a motion picture studio, after his acclaim on Broadway, she moved with her family to Hollywood, where Gene made around 300 films. After attending school in Beverly Hills, June started her professional life in films, mostly in minor roles in prestigious pictures such as Sergeant York (1941), The White Cliffs of Dover (1942) and Meet Me in St Louis (1944). In the last one, she is delightful as a New Yorker at a family party, whose dance card is arranged spitefully to stop Lockhart interacting with her brother.
More importantly, although she did not know it at the time, was Son of Lassie (1945). It was one of multiple follow-ups to the extremely successful Lassie Come Home (1943), in which a young star had played the female character who assists the canine to escape to the owners. In the subsequent film, Lockhart played the now adult character.
The loving way in which she handled both Lassie and her offspring, Laddie, protagonist of a World War II story in Nazi-occupied Norway, was in the consideration of the producers when it came to selecting the Lassie TV series 13 years later.
Transition to Television and Stage Success
Although she was given leading roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her movie career was stagnating and that television would be the solution. Before embarking in a new direction, she received acclaim on Broadway in For Love or Money (1947), a humorous play for which she won a Tony award as most promising newcomer.
A additional substantial run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a physician and maternal character. She also featured regularly in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy schedule continued for the next five decades, with a recurring role in General Hospital between 1984 and 1998. Among her many one-off appearances were as herself in a 1988 episode of a comedy series, where the host finds a stray collie, and in another sitcom in 1995 as the mother of a dining manager.
Later Roles and Contributions
Her final TV credit came in 2021 as the voice of Alpha Control in an episode of a streaming service’s new version of Lost in Space. In the movie version featuring well-known actors (1998), she had a holographic cameo as a school principal. She took pleasure in learning how much of an inspiration the first series had been to later astronauts, and often participated in the organization’s launches and other events. In 2013 her work as a unpaid spokesperson brought her its prestigious award.
Among her few subsequent feature films was the fantasy, Troll (1986) in which she played a witch, with her own daughter, Anne Lockhart, playing her earlier self.
Personal Life and Family
In 1951 she wed John Maloney, a physician and former Navy medical officer. In addition to Anne, they had another daughter, June. That marriage ended in divorce, as did her second marriage, to John Lindsay, an architect.
She is remembered by her daughters and four grandchildren.
