Launching her career in films, June Lockhart, who died aged 100, found her greatest success after switching largely to television. Having been offered few chances to excel in movies from her debut as a child in 1938 until 1947, she excelled on television in many beloved series, especially in Lassie.
Her Iconic Role in Lassie
Taking over from a previous star in 1958, Lockhart remained in the show until 1964. Her role was Ruth Martin, married to agriculturalist Paul Martin and the foster mother of young Timmy Martin, whose dog was the titular star of the series.
Despite playing a mother figure, Lockhart skillfully avoided being outshone by the smart animal star. She characterized the show as “a fantasy about people on a rural property in which the dog resolves all the issues in 22 minutes, in time for the last commercial”. After she left the series, Lockhart commented: “In six sexless years of playing a country spouse and mother, I was rarely allowed to kiss my on-screen husband on the face.”
Adventure into Lost in Space
Lockhart went straight into a second successful series, 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 portrayed Maureen and John Robinson, two researchers investigating alien planets. Lockhart had to spend most of her time skillfully trying to navigate special effects. As the series continued, the storyline became less and less about this interstellar clan and increasingly about the boy and his friendship with a mechanical being, and the timid villain Dr Zachary Smith.
Early Career and Family Influence
Lockhart’s feature film debut, at the 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 British-born Kathleen and Canadian-born Gene were both performers in many of movies, as well as on stage, it was almost certain that June, who was born in New York, would join show business.
Her first stage performance, at the age of six, came in a non-singing role in an opera at the Metropolitan Opera in New York (1931).
Transition to Hollywood and Film Roles
When her father was offered a contract 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 movies, 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 schedule is filled maliciously to prevent Lockhart interacting with her sibling.
More importantly, although she did not realize it at the time, was Son of Lassie (1945). It was one of multiple sequels to the extremely successful Lassie Come Home (1943), in which a young star had played the female character 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 offspring, Laddie, protagonist of a wartime story in Nazi-occupied Norway, was in the consideration of the creators when it came to casting the Lassie TV series 13 years later.
Television and Theater Career
Although she was given major 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 embarking in a different direction, she won praise 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 maternal character. She also appeared frequently in TV cowboy shows 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 recurring role in General Hospital between 1984 and 1998. Among her many one-off appearances were as the actress in a 1988 episode of a comedy series, where the presenter finds a stray collie, and in another sitcom in 1995 as the mother of a restaurant manager.
Final Career and Legacy
Her final TV appearance 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 big screen version starring 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 attended 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 played a sorceress, with her own daughter, Anne Lockhart, playing her earlier self.
Personal Life and Family
In 1951 she married John Maloney, a doctor and former Navy doctor. In addition to Anne, they had another daughter, June. That union ended in separation, as did her subsequent marriage, to John Lindsay, an architect.
She is survived by her children and four grandchildren.
