June Lockhart, who died at the age of 100, began her professional journey in movies, but gained fame after transitioning almost entirely to TV. Having been given limited opportunities to shine in movies from her first appearance as a child in 1938 until 1947, she excelled on TV in numerous popular 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. Her role was Ruth Martin, wed to agriculturalist Paul Martin and the foster mother of seven-year-old Timmy Martin, whose collie was the titular hero of the series.
In her role as a homemaker, Lockhart somehow succeeded to avoid being totally overshadowed by the clever dog. She described the show as “a fairy tale about families on a farm in which the dog resolves all the problems in 22 minutes, in time for the last advertisement”. After she left the series, Lockhart commented: “In six chaste years of playing a country wife and mother, I was rarely allowed to kiss my on-screen husband on the cheek.”
Starring in Lost in Space
Lockhart went straight into another successful series, Lost in Space (1965-68), a semi-spoof sci-fi series aimed primarily at young audiences and inspired by The Swiss Family Robinson. Lockhart and her co-star played Maureen and John Robinson, two scientists exploring distant planets. Lockhart had to spend most of her time skillfully trying to survive special effects. As the series continued, the storyline became increasingly less about this space clan and more about the boy and his bond with a mechanical being, and the cowardly villain Dr Zachary Smith.
Initial Career and Family Background
Lockhart’s movie first role, at the young 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 real-life parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canadian-born Gene were both performers in dozens of films, as well as on stage, it was nearly inevitable that June, who was born in New York, would join show business.
Her first stage appearance, at the age of six, came in a non-musical role in an musical production at the Metropolitan Opera in New York (1931).
Cinema Career
When her parent was given a contract by a motion picture studio, after his acclaim on Broadway, she relocated with her family to Hollywood, where Gene made approximately 300 films. After attending school in Beverly Hills, June started her professional life in films, mostly in small 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 charming as a New Yorker at a household party, whose schedule is filled maliciously to stop Lockhart interacting with her brother.
More importantly, although she did not realize 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 helps the canine to return to the family. In the subsequent film, Lockhart played the now grown-up version.
The loving way in which she interacted with both Lassie and her offspring, Laddie, protagonist of a wartime 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 Career
Although she was offered leading roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her movie career was stagnating and that TV would be the answer. Before going in a new direction, she received acclaim on Broadway in For Love or Money (1947), a comedy for which she won a Tony award as most promising newcomer.
A further substantial run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a doctor and mother figure. She also featured frequently in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy workload continued for the following 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 talkshow, where the presenter finds a stray collie, and in another sitcom in 1995 as the mother of a dining manager.
Later Roles and Achievements
Her final TV credit came in 2021 as the narration of Alpha Control in an episode of a streaming service’s remake of Lost in Space. In the movie version starring well-known actors (1998), she had a digital cameo as a school principal. She took joy in learning how much of an inspiration the original series had been to later astronauts, and often participated in the agency’s launches and other events. In 2013 her work as a unpaid representative brought her its Exceptional Public Achievement Medal.
Among her limited 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 married John Maloney, a physician and former Navy doctor. In addition to Anne, they had another daughter, June. That marriage ended in separation, as did her subsequent marriage, to John Lindsay, an designer.
She is survived by her children and four grandkids.
