June Lockhart, who passed away at the remarkable age of 100, began her professional journey in films, but gained recognition after transitioning almost exclusively to television. Having been given few chances to shine in movies from her debut as a youngster 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, wed to agriculturalist Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose collie was the eponymous hero of the series.
In her part as a housewife, Lockhart somehow managed to avoid being completely upstaged by the clever canine. She described the program as “a fantasy about families on a farm in which the canine solves all the problems in 22 minutes, in time for the last commercial”. After she left the show, Lockhart commented: “In six sexless years of playing a rural wife and mother, I was rarely allowed to peck my on-screen husband on the face.”
Adventure into Lost in Space
Lockhart went directly into another hit, Lost in Space (1965-68), a semi-spoof science fiction series targeted primarily at children and inspired by The Swiss Family Robinson. Lockhart and another actor portrayed Maureen and John Robinson, two researchers investigating alien planets. Lockhart had to spend the majority of her time skillfully trying to survive special effects. As the show progressed, the storyline became less and less about this space clan and increasingly about the boy and his friendship with a mechanical being, and the cowardly antagonist Dr Zachary Smith.
Early Career and Family Influence
Lockhart’s feature film debut, 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 UK-native Kathleen and Canada-native 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 the entertainment industry.
Her first theatrical performance, 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 film studio, after his success on Broadway, she relocated with her family to Hollywood, where Gene made around 300 films. After going to school in Beverly Hills, June started her professional life in movies, mainly in small 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 household party, whose dance card is arranged maliciously to stop Lockhart interacting with her brother.
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 a young star had played the female character who assists the dog to return to the family. In the later film, Lockhart played the now grown-up version.
The loving way in which she handled both Lassie and her offspring, Laddie, hero of a wartime adventure in Nazi-occupied Norway, was in the minds of the creators when it came to selecting the Lassie TV series 13 years later.
TV and Theater Career
Although she was given leading roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her film career was stagnating and that television would be the solution. Before embarking 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 most promising newcomer.
A further substantial run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a physician and mother figure. She also appeared 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 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 Impact
Her last TV credit 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 influence the original series had been to later astronauts, and often attended the agency’s launches and other events. In 2013 her work as a volunteer spokesperson brought her its prestigious award.
Among her limited later feature films was the fantasy, Troll (1986) in which she portrayed a sorceress, with her own daughter, Anne Lockhart, playing her earlier self.
Personal Details
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 divorce, as did her subsequent marriage, to John Lindsay, an architect.
She is remembered by her daughters and four grandchildren.
