June Lockhart, who died at the remarkable age of 100, began her professional journey in films, but gained recognition after moving almost exclusively to TV. Having been offered limited opportunities to excel in films from her debut as a child in 1938 until 1947, she excelled on television in numerous beloved series, especially in Lassie.
Portraying Ruth Martin on Lassie
Taking over from another actress in 1958, Lockhart continued in the series until 1964. She played Ruth Martin, wed to agriculturalist Paul Martin and the foster mother of young Timmy Martin, whose collie was the titular hero of the series.
In her part as a housewife, Lockhart somehow managed to avoid being totally upstaged by the intelligent dog. She characterized the program as “a fantasy about people on a rural property in which the dog 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 rural wife and parent, I was rarely permitted to peck my on-screen husband on the cheek.”
Starring in Lost in Space
Lockhart went straight into another successful series, Lost in Space (1965-68), a partly comedic sci-fi series targeted primarily at children and based by The Swiss Family Robinson. Lockhart and her co-star portrayed Maureen and John Robinson, two scientists investigating distant planets. Lockhart had to spend the majority of her time deftly trying to navigate visual effects. As the series progressed, the narrative 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.
Beginnings in Entertainment
Lockhart’s feature film 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 actual parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canada-native Gene were both actors 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 performance, at the age of six, came in a non-musical role in an musical production at the Metropolitan Opera in New York (1931).
Move to Hollywood and Film Roles
When her parent was given a deal by a film studio, after his acclaim on Broadway, she moved with her family to Hollywood, where Gene made around 300 films. After attending 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 stop Lockhart interacting 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 helps the canine to escape to the owners. In the later film, Lockhart played the now adult character.
The loving way in which she interacted with both Lassie and her son, Laddie, protagonist of a wartime adventure in Nazi-occupied Norway, was in the minds of the creators when it came to selecting the Lassie TV series 13 years later.
Television and Theater Work
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 answer. Before embarking in a different 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 further substantial run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a doctor and mother figure. She also appeared regularly in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy 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 the actress in a 1988 episode of a comedy series, where the presenter finds a lost collie, and in another sitcom in 1995 as the parent of a restaurant manager.
Later Roles and Achievements
Her last TV credit came in 2021 as the voice 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 holographic cameo as a school principal. She took joy 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 volunteer spokesperson brought her its Exceptional Public Achievement Medal.
Among her few subsequent feature films was the fantasy, Troll (1986) in which she played a witch, with her own daughter, Anne Lockhart, playing her younger self.
Private Information
In 1951 she married John Maloney, a physician and former Navy medical officer. In addition to Anne, they had another daughter, June. That marriage ended in divorce, as did her second marriage, to John Lindsay, an designer.
She is remembered by her children and four grandchildren.
