June Lockhart, who passed away at the age of 100, started her professional journey in movies, but achieved fame after transitioning almost entirely to television. Having been offered few chances to shine in movies from her debut as a child in 1938 until 1947, she thrived on television in many beloved series, especially in Lassie.
Her Iconic Role in Lassie
Stepping in from a previous star in 1958, Lockhart remained in the show until 1964. She played Ruth Martin, married to farmer Paul Martin and the foster mother of young Timmy Martin, whose dog was the eponymous hero of the series.
Despite playing a housewife, Lockhart skillfully avoided being overshadowed by the smart animal star. She described the show as “a fairy tale about families on a farm in which the canine solves all the problems in 22 minutes, in time for the last commercial”. After she departed the series, Lockhart commented: “In six chaste years of playing a country spouse and parent, I was rarely allowed to kiss my on-screen husband on the cheek.”
Journey into Lost in Space
Lockhart went straight into a second hit, Lost in Space (1965-68), a semi-spoof sci-fi series aimed primarily at young audiences and inspired by The Swiss Family Robinson. Lockhart and her co-star portrayed Maureen and John Robinson, two researchers investigating distant planets. Lockhart had to spend the majority of her time skillfully trying to survive visual effects. As the series continued, the storyline became less and less about this space family and increasingly about the young son and his bond with a robot, and the cowardly antagonist Dr Zachary Smith.
Start in Show Business
Lockhart’s movie first role, 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 British-born Kathleen and Canada-native Gene were both actors in dozens of films, as well as on stage, it was nearly inevitable 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 musical production 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 approximately 300 films. After attending school in Beverly Hills, June began her career 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 delightful as a New Yorker at a family party, whose schedule is arranged maliciously to prevent Lockhart dancing 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 girl who helps the canine to return to the owners. In the later film, Lockhart played the now adult character.
The affectionate way in which she interacted with both Lassie and her son, Laddie, protagonist of a World War II adventure in enemy-held Norway, was in the minds of the producers when it came to selecting the Lassie TV series 13 years later.
Transition to Television and Stage Achievement
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 getting her nowhere and that TV would be the answer. Before embarking in a new direction, she received acclaim on Broadway in For Love or Money (1947), a humorous play for which she won a Tony award as best newcomer.
A additional substantial run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a doctor and maternal character. She also featured regularly in TV westerns 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 regular role in General Hospital between 1984 and 1998. Among her many one-off 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 mother of a restaurant manager.
Final Roles and Achievements
Her final TV appearance came in 2021 as the narration of Alpha Control in an episode of a digital platform’s new version of Lost in Space. In the big screen version starring famous actors (1998), she had a digital 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 participated in the organization’s launches and other events. In 2013 her work as a unpaid spokesperson brought her its prestigious award.
Among her few later feature films was the fantasy, Troll (1986) in which she portrayed a witch, 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 union ended in divorce, as did her second marriage, to John Lindsay, an architect.
She is remembered by her children and four grandkids.
