Starting her career in cinema, June Lockhart, who passed on aged 100, achieved her greatest success after shifting largely to the small screen. Having been offered few opportunities to shine in movies from her debut as a child in 1938 until 1947, she excelled on TV in many beloved series, especially in Lassie.
Her Iconic Role in Lassie
Stepping in from another actress in 1958, Lockhart remained in the series until 1964. She played Ruth Martin, married to farmer Paul Martin and the foster mother of young Timmy Martin, whose dog was the eponymous hero of the series.
In her role as a homemaker, Lockhart somehow succeeded to avoid being totally upstaged by the intelligent canine. She characterized the show as “a fantasy about families on a farm in which the canine resolves all the problems in 22 minutes, in time for the last advertisement”. After she left the show, Lockhart remarked: “In six sexless years of playing a rural wife and mother, I was rarely permitted to peck my on-screen husband on the face.”
Featuring in Lost in Space
Lockhart went straight into another successful series, Lost in Space (1965-68), a partly comedic science fiction series aimed primarily at children 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 visual effects. As the show continued, the storyline became less and less about this interstellar clan and more about the young son and his friendship with a robot, and the cowardly antagonist Dr Zachary Smith.
Early Career and Family Background
Lockhart’s movie first role, at the age of 13, had come as Belinda Cratchit in A Christmas Carol (1938). In the parts 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 many of films, as well as on stage, it was almost inevitable that June, who was born in New York, would join the entertainment industry.
Her first stage appearance, at the age of six, came in a non-singing role in an musical production at the Metropolitan Opera in New York (1931).
Cinema Work
When her father was given a contract by a motion picture studio, after his success on Broadway, she moved with her family to Hollywood, where Gene made around 300 films. After attending school in Beverly Hills, June began her professional life in movies, mostly in minor roles in acclaimed 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 charming as a New Yorker at a family party, whose schedule is arranged maliciously to prevent Lockhart interacting with her brother.
More significantly, although she did not realize it at the time, was Son of Lassie (1945). It was one of several follow-ups to the extremely successful Lassie Come Home (1943), in which another actress had played the girl who assists the canine to return to the family. In the later film, Lockhart played the now grown-up version.
The affectionate way in which she interacted with both Lassie and her son, Laddie, hero of a World War II story in enemy-held Norway, was in the consideration of the producers when it came to casting the Lassie TV series 13 years later.
TV and Stage Work
Although she was offered major roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her film career was getting her nowhere and that TV would be the solution. Before going in a different direction, she received praise on Broadway in For Love or Money (1947), a comedy for which she won a Tony award as best 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 appeared regularly in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy workload persisted for the next five decades, with a regular 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 lost collie, and in another sitcom in 1995 as the mother of a restaurant manager.
Final Career and Impact
Her final TV credit came in 2021 as the narration of Alpha Control in an episode of a digital platform’s remake of Lost in Space. In the big screen 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 original series had been to future astronauts, and often participated in the organization’s launches and other events. In 2013 her work as a volunteer representative brought her its Exceptional Public Achievement Medal.
Among her few subsequent feature films was the fantasy, Troll (1986) in which she portrayed a witch, with her own daughter, Anne Lockhart, playing her younger self.
Personal Life and Family
In 1951 she wed John Maloney, a physician and former Navy doctor. In addition to Anne, they had another daughter, June. That union ended in separation, as did her second marriage, to John Lindsay, an architect.
She is survived by her daughters and four grandkids.
