June Lockhart, who died at the remarkable age of 100, started her career in films, but gained fame after moving almost exclusively to television. Having been given limited chances to excel in films from her debut as a youngster in 1938 until 1947, she excelled on television in many beloved series, especially in Lassie.
Portraying Ruth Martin on Lassie
Stepping in from a previous star in 1958, Lockhart continued in the show until 1964. Her role was Ruth Martin, married to farmer Paul Martin and the adoptive mother of young Timmy Martin, whose collie was the eponymous star of the series.
In her role as a housewife, Lockhart somehow succeeded to avoid being completely overshadowed by the clever canine. She characterized the show as “a fantasy about people on a rural property in which the canine solves all the issues in 22 minutes, in time for the last advertisement”. After she left the show, Lockhart remarked: “In six chaste years of playing a rural spouse and parent, I was hardly ever permitted to peck my on-screen husband on the cheek.”
Journey into Lost in Space
Lockhart went directly into a second hit, Lost in Space (1965-68), a semi-spoof sci-fi series aimed mostly 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 increasingly less about this space family and more about the young son and his friendship with a robot, and the cowardly villain Dr Zachary Smith.
Early Career and Family Influence
Lockhart’s movie 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 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 theater, it was nearly 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 opera at the Metropolitan Opera in New York (1931).
Cinema Career
When her parent was offered a deal by a motion picture studio, after his acclaim on Broadway, she moved with her family to Hollywood, where Gene made approximately 300 films. After going to school in Beverly Hills, June started her professional life 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 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 brother.
More importantly, although she did not know it at the time, was Son of Lassie (1945). It was one of multiple follow-ups to the hugely successful Lassie Come Home (1943), in which another actress had played the female character who assists the canine to return to the owners. In the subsequent film, Lockhart played the now grown-up character.
The loving way in which she interacted with both Lassie and her son, Laddie, protagonist of a World War II story in Nazi-occupied Norway, was in the minds of the producers when it came to casting the Lassie TV series 13 years later.
Transition to Television and Stage Success
Although she was offered major roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her movie career was getting her nowhere and that TV would be the solution. Before embarking in a new direction, she won acclaim on Broadway in For Love or Money (1947), a humorous play for which she won a Tony award as most promising newcomer.
A additional significant run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a physician and maternal character. She also featured frequently in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy schedule persisted for the following 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 presenter finds a lost collie, and in another sitcom in 1995 as the mother of a dining manager.
Later Roles and Achievements
Her final TV credit came in 2021 as the narration of Alpha Control in an episode of a digital platform’s remake of Lost in Space. In the movie version starring well-known actors (1998), she had a holographic cameo as a school principal. She took pleasure 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 unpaid spokesperson brought her its prestigious award.
Among her limited subsequent feature films was the fantasy, Troll (1986) in which she played a witch, with her own daughter, Anne Lockhart, playing her earlier self.
Personal Information
In 1951 she married John Maloney, a physician and former Navy doctor. In addition to Anne, they had a second daughter, June. That union ended in separation, as did her second marriage, to John Lindsay, an architect.
She is survived by her children and four grandchildren.
