Starting her career in films, June Lockhart, who passed on aged 100, found her biggest success after switching predominantly to the small screen. Having been given few chances to excel in movies from her debut as a child in 1938 until 1947, she excelled on television in numerous beloved series, most notably in Lassie.
Her Memorable Role in Lassie
Stepping in from a previous star in 1958, Lockhart remained in the show until 1964. Her role was Ruth Martin, wed to agriculturalist Paul Martin and the foster mother of seven-year-old Timmy Martin, whose dog was the eponymous star 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 fantasy about people on a farm in which the dog resolves all the issues in 22 minutes, in time for the last advertisement”. After she departed the show, Lockhart commented: “In six chaste years of playing a country wife and mother, I was rarely permitted to peck my on-screen husband on the face.”
Journey into Lost in Space
Lockhart went straight into another hit, Lost in Space (1965-68), a semi-spoof sci-fi series targeted primarily at children and inspired by The Swiss Family Robinson. Lockhart and her co-star played Maureen and John Robinson, two researchers exploring alien planets. Lockhart had to spend the majority of her time deftly trying to survive visual effects. As the series continued, the narrative became less and less about this space family and more about the boy and his bond with a mechanical being, and the cowardly antagonist Dr Zachary Smith.
Early Career and Family Influence
Lockhart’s movie debut, at the young age of 13, had come as Belinda Cratchit in A Christmas Carol (1938). In the parts of her parents, Bob and Mrs Cratchit, were her actual parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canada-native Gene were both performers in dozens of movies, as well as on theater, it was nearly certain that June, who was born in New York, would join show business.
Her first theatrical 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 Career
When her father was offered a deal by a film studio, after his acclaim on Broadway, she relocated with her parents to Hollywood, where Gene made approximately 300 films. After attending school in Beverly Hills, June began her career 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 latter, she is delightful as a New Yorker at a family party, whose dance card is arranged spitefully to stop Lockhart dancing with her brother.
More significantly, although she did not realize 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 a young star had played the female character who assists the canine to escape to the family. In the later film, Lockhart played the now grown-up version.
The affectionate way in which she handled both Lassie and her son, Laddie, hero of a World War II adventure in enemy-held Norway, was in the minds of the creators when it came to casting the Lassie TV series 13 years later.
Transition to Television and Broadway Success
Although she was given leading roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her film career was stagnating and that television would be the answer. Before going in a different 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 further significant run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a physician and mother figure. She also featured regularly in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic workload persisted for the following five decades, with a recurring role in General Hospital between 1984 and 1998. Among her many guest 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 parent of a dining manager.
Later Roles and Contributions
Her last TV appearance came in 2021 as the narration of Alpha Control in an episode of a streaming service’s new version of Lost in Space. In the big screen 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 first series had been to later astronauts, and often attended the organization’s launches and other events. In 2013 her work as a volunteer spokesperson brought her its Exceptional Public Achievement Medal.
Among her limited subsequent feature films was the fantasy, Troll (1986) in which she portrayed a sorceress, with her own daughter, Anne Lockhart, playing her earlier self.
Personal Life and Family
In 1951 she wed John Maloney, a doctor and former Navy medical officer. In addition to Anne, they had another daughter, June. That marriage ended in divorce, as did her subsequent marriage, to John Lindsay, an architect.
She is survived by her children and four grandkids.
