June Lockhart, who passed away at the remarkable age of 100, began her career in films, but gained recognition after transitioning almost entirely to television. Having been offered few chances to shine in films from her first appearance as a youngster in 1938 until 1947, she thrived on television in numerous popular series, most notably in Lassie.
Her Memorable Role in Lassie
Stepping in from another actress in 1958, Lockhart continued in the series until 1964. She played Ruth Martin, married to agriculturalist Paul Martin and the foster mother of seven-year-old Timmy Martin, whose collie was the eponymous star of the series.
Even with playing a mother figure, Lockhart adeptly avoided being outshone by the brilliant animal star. She characterized the program as “a fantasy about families on a rural property in which the dog solves all the problems in 22 minutes, in time for the last commercial”. After she left the series, 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 straight into a second hit, Lost in Space (1965-68), a semi-spoof sci-fi series targeted primarily at young audiences and based by The Swiss Family Robinson. Lockhart and another actor played 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 series progressed, the storyline became increasingly less about this space clan and increasingly about the boy and his bond with a mechanical being, and the cowardly villain Dr Zachary Smith.
Initial Career and Family Influence
Lockhart’s movie first role, at the age of 13, had come as Belinda Cratchit in A Christmas Carol (1938). In the roles of her parents, Bob and Mrs Cratchit, were her real-life parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canada-native Gene were both performers in dozens of movies, as well as on stage, it was almost 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-singing role in an musical production at the Metropolitan Opera in New York (1931).
Move to Hollywood and Movie Roles
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 started her career in films, mostly in minor 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 family party, whose schedule is filled spitefully to prevent Lockhart dancing with her sibling.
More significantly, although she did not realize it at the time, was Son of Lassie (1945). It was one of multiple sequels to the hugely 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 handled both Lassie and her offspring, Laddie, hero of a World War II adventure in Nazi-occupied Norway, was in the minds of the producers when it came to selecting the Lassie TV series 13 years later.
TV and Theater Career
Although she was given major roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her movie career was stagnating and that TV would be the solution. Before embarking in a new direction, she received praise on Broadway in For Love or Money (1947), a humorous play 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 appeared regularly in TV cowboy shows 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 regular role in General Hospital between 1984 and 1998. Among her many one-off appearances were as herself in a 1988 episode of a comedy series, where the host finds a stray collie, and in another sitcom in 1995 as the mother of a restaurant manager.
Final Roles and Contributions
Her last TV appearance came in 2021 as the narration of Alpha Control in an episode of a streaming service’s remake of Lost in Space. In the big screen version featuring famous actors (1998), she had a digital cameo as a school principal. She took joy in learning how much of an influence the first series had been to later astronauts, and often participated in the organization’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 played a witch, with her own daughter, Anne Lockhart, playing her younger self.
Personal Life and Family
In 1951 she wed John Maloney, a physician and former Navy medical officer. 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 remembered by her daughters and four grandchildren.
