June Lockhart, who passed away at the age of 100, began her professional journey in movies, but gained fame after transitioning almost exclusively to television. Having been given limited chances to shine in movies from her first appearance as a child in 1938 until 1947, she excelled on TV in numerous popular series, most notably in Lassie.
Her Memorable Role in Lassie
Stepping in from another actress in 1958, Lockhart remained in the show until 1964. Her role was Ruth Martin, wed to agriculturalist Paul Martin and the foster mother of young Timmy Martin, whose dog was the titular star of the series.
Despite playing a mother figure, Lockhart skillfully avoided being outshone by the brilliant dog. She characterized the show as “a fantasy about people on a farm in which the dog solves all the problems in 22 minutes, in time for the last commercial”. After she departed the show, Lockhart remarked: “In six chaste years of playing a rural wife and parent, I was hardly ever allowed to kiss my co-star on the cheek.”
Featuring in Lost in Space
Lockhart went straight into a second successful series, Lost in Space (1965-68), a partly comedic sci-fi series targeted mostly at children and inspired by The Swiss Family Robinson. Lockhart and her co-star played Maureen and John Robinson, two researchers investigating alien planets. Lockhart had to spend most of her time skillfully trying to survive visual effects. As the series progressed, the storyline became less and less about this interstellar family and increasingly about the boy and his friendship with a robot, and the timid antagonist Dr Zachary Smith.
Early Career and Family Background
Lockhart’s feature film debut, at the young 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 actors in many of movies, as well as on theater, it was almost inevitable that June, who was born in New York, would enter show business.
Her first theatrical appearance, at the age of six, came in a non-singing role in an musical production at the Metropolitan Opera in New York (1931).
Cinema Career
When her father was given a contract by a film studio, after his success on Broadway, she moved with her family to Hollywood, where Gene made around 300 films. After going to school in Beverly Hills, June started her professional life in films, mainly in minor 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 delightful as a New Yorker at a family party, whose dance card is arranged spitefully 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 sequels to the hugely successful Lassie Come Home (1943), in which a young star had played the female character who helps the canine to escape to the owners. In the subsequent film, Lockhart played the now grown-up character.
The loving way in which she handled both Lassie and her son, Laddie, protagonist of a World War II story in enemy-held Norway, was in the consideration of the creators when it came to casting the Lassie TV series 13 years later.
Shift to Television and Broadway Achievement
Although she was offered leading roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her movie career was stagnating and that television would be the solution. Before embarking 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 significant run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a physician and mother figure. She also featured regularly in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic schedule 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 talkshow, where the presenter finds a stray collie, and in another sitcom in 1995 as the mother of a restaurant manager.
Later Roles and Contributions
Her final TV appearance came in 2021 as the voice of Alpha Control in an episode of a streaming service’s remake of Lost in Space. In the movie 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 attended the organization’s launches and other events. In 2013 her work as a volunteer spokesperson brought her its Exceptional Public Achievement Medal.
Among her few subsequent feature films was the fantasy, Troll (1986) in which she portrayed a witch, with her own daughter, Anne Lockhart, playing her younger self.
Private Information
In 1951 she wed John Maloney, a physician and former Navy doctor. In addition to Anne, they had another daughter, June. That union ended in divorce, as did her subsequent marriage, to John Lindsay, an architect.
She is remembered by her children and four grandchildren.
