Launching her career in films, June Lockhart, who passed on aged 100, found her greatest success after shifting largely to television. Having been offered few opportunities to shine in movies from her debut as a child in 1938 until 1947, she thrived on TV in numerous popular series, especially in Lassie.
Her Iconic Role in Lassie
Taking over from another actress in 1958, Lockhart remained in the show until 1964. She played Ruth Martin, wed to agriculturalist Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose collie was the eponymous hero of the series.
Even with playing a mother figure, Lockhart skillfully avoided being outshone by the brilliant animal star. She characterized the show as “a fairy tale about people on a rural property in which the canine solves all the problems in 22 minutes, in time for the last commercial”. After she left the show, Lockhart remarked: “In six sexless years of playing a country spouse and parent, I was hardly ever permitted to kiss my on-screen husband on the cheek.”
Journey into Lost in Space
Lockhart went straight into another hit, Lost in Space (1965-68), a semi-spoof science fiction series targeted primarily at young audiences and inspired by The Swiss Family Robinson. Lockhart and another actor portrayed Maureen and John Robinson, two scientists investigating alien planets. Lockhart had to spend most of her time skillfully trying to survive special effects. As the series progressed, the narrative became increasingly less about this space family and more about the boy and his friendship with a mechanical being, and the timid antagonist Dr Zachary Smith.
Start in Show Business
Lockhart’s feature film debut, 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 real-life parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canadian-born Gene were both actors in dozens of films, as well as on stage, it was nearly inevitable that June, who was born in New York, would enter show business.
Her first stage appearance, at the age of six, came in a non-musical role in an opera at the Metropolitan Opera in New York (1931).
Transition to Hollywood and Film Roles
When her parent was given a contract by a film studio, after his acclaim on Broadway, she relocated with her parents to Hollywood, where Gene made approximately 300 films. After going to school in Beverly Hills, June started her career in movies, 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 family party, whose dance card is arranged maliciously to prevent Lockhart dancing with her sibling.
More significantly, although she did not know it at the time, was Son of Lassie (1945). It was one of several sequels to the hugely successful Lassie Come Home (1943), in which another actress had played the female character who assists the canine to escape to the family. In the subsequent film, Lockhart played the now grown-up character.
The affectionate way in which she interacted with both Lassie and her offspring, Laddie, hero of a wartime story in enemy-held Norway, was in the minds of the producers when it came to casting the Lassie TV series 13 years later.
Transition to Television and Broadway Success
Although she was offered leading roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her film career was getting her nowhere and that television would be the answer. Before going in a new 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 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 regularly in TV westerns 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 guest appearances were as the actress in a 1988 episode of a talkshow, where the host finds a stray collie, and in another sitcom in 1995 as the mother of a dining manager.
Later Career and Impact
Her last TV credit came in 2021 as the voice of Alpha Control in an episode of a digital platform’s new version of Lost in Space. In the movie version starring well-known actors (1998), she had a holographic cameo as a school principal. She took joy in learning how much of an influence the first series had been to future astronauts, and often participated in the organization’s launches and other events. In 2013 her work as a unpaid spokesperson brought her its Exceptional Public Achievement Medal.
Among her limited later 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 married John Maloney, a physician and former Navy doctor. In addition to Anne, they had a second daughter, June. That marriage ended in separation, as did her second marriage, to John Lindsay, an architect.
She is survived by her children and four grandkids.
