June Lockhart, who died at the age of 100, started her professional journey in films, but gained recognition after moving almost entirely to television. Having been given limited chances to excel in movies from her debut as a child in 1938 until 1947, she excelled on television in many popular series, especially in Lassie.
Her Memorable Role in Lassie
Taking over from another actress in 1958, Lockhart remained in the series 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.
Despite playing a mother figure, Lockhart adeptly avoided being overshadowed by the brilliant dog. She characterized the program as “a fairy tale about people on a farm in which the dog 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 country spouse and mother, I was rarely permitted to peck my co-star on the cheek.”
Starring in Lost in Space
Lockhart went straight into a second hit, Lost in Space (1965-68), a partly comedic sci-fi series targeted mostly at young audiences and based 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 navigate visual effects. As the series continued, the storyline became less and less about this space clan and more about the boy and his bond with a mechanical being, and the cowardly villain Dr Zachary Smith.
Beginnings in Entertainment
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 many of films, as well as on theater, it was almost inevitable that June, who was born in New York, would enter the entertainment industry.
Her first stage performance, at the age of six, came in a non-musical role in an musical production at the Metropolitan Opera in New York (1931).
Transition to Hollywood and Movie Roles
When her parent was offered a deal by a film studio, after his acclaim on Broadway, she moved with her parents to Hollywood, where Gene made around 300 films. After attending school in Beverly Hills, June started her professional life in movies, 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 latter, she is charming as a New Yorker at a family party, whose schedule is filled spitefully to prevent Lockhart dancing with her brother.
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 character.
The affectionate way in which she handled both Lassie and her offspring, Laddie, hero of a wartime adventure in enemy-held Norway, was in the consideration of the creators when it came to selecting the Lassie TV series 13 years later.
Transition to Television and Broadway Achievement
Although she was offered leading roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her movie career was getting her nowhere and that television would be the solution. Before going in a different direction, she won acclaim on Broadway in For Love or Money (1947), a comedy for which she won a Tony award as best newcomer.
A further substantial run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a doctor and maternal character. She also featured regularly in TV cowboy shows 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 regular role in General Hospital between 1984 and 1998. Among her many guest appearances were as the actress in a 1988 episode of a talkshow, where the presenter finds a stray collie, and in another sitcom in 1995 as the parent of a dining manager.
Final Roles and Contributions
Her last TV appearance 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 featuring famous actors (1998), she had a holographic cameo as a school principal. She took pleasure in learning how much of an inspiration the original series had been to later astronauts, and often participated in the agency’s launches and other events. In 2013 her work as a unpaid spokesperson brought her its Exceptional Public Achievement Medal.
Among her few 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 Details
In 1951 she wed John Maloney, a doctor and former Navy doctor. In addition to Anne, they had a second daughter, June. That union ended in divorce, as did her subsequent marriage, to John Lindsay, an designer.
She is survived by her daughters and four grandkids.
