Starting her career in films, June Lockhart, who died aged 100, achieved her greatest success after switching predominantly to television. Having been given limited opportunities to shine in films from her debut as a child in 1938 until 1947, she thrived on television in numerous popular series, most notably in Lassie.
Her Iconic Role in Lassie
Stepping in from another actress in 1958, Lockhart remained in the series until 1964. Her role was Ruth Martin, wed to agriculturalist Paul Martin and the foster mother of seven-year-old Timmy Martin, whose collie was the eponymous star of the series.
Despite playing a housewife, Lockhart skillfully avoided being outshone by the smart dog. She characterized the program as “a fairy tale about families on a rural property in which the canine resolves all the issues in 22 minutes, in time for the last advertisement”. After she departed the show, Lockhart remarked: “In six sexless years of playing a rural spouse and mother, I was hardly ever allowed to kiss my on-screen husband on the face.”
Featuring in Lost in Space
Lockhart went directly into a second successful series, Lost in Space (1965-68), a semi-spoof science fiction series targeted mostly at children and inspired by The Swiss Family Robinson. Lockhart and another actor portrayed Maureen and John Robinson, two researchers exploring 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 space clan and more about the boy and his friendship with a robot, and the timid antagonist Dr Zachary Smith.
Initial Career and Family Background
Lockhart’s movie debut, at the young age of 13, had come as Belinda Cratchit in A Christmas Carol (1938). In the roles of her mother and father, Bob and Mrs Cratchit, were her real-life parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canada-native Gene were both actors in dozens of movies, as well as on theater, it was almost certain that June, who was born in New York, would enter the entertainment industry.
Her first stage performance, at the tender age of six, came in a non-musical role in an opera at the Metropolitan Opera in New York (1931).
Transition to Hollywood and Film Roles
When her father was given a deal by a film studio, after his acclaim on Broadway, she moved with her parents to Hollywood, where Gene made approximately 300 films. After attending school in Beverly Hills, June started her professional life in movies, mainly in minor roles in acclaimed pictures such as Sergeant York (1941), The White Cliffs of Dover (1942) and Meet Me in St Louis (1944). In the latter, she is delightful as a New Yorker at a household party, whose schedule is arranged spitefully to stop Lockhart interacting with her brother.
More importantly, although she did not realize 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 dog 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 offspring, Laddie, protagonist of a World War II story in Nazi-occupied Norway, was in the minds of the creators when it came to selecting the Lassie TV series 13 years later.
Transition to Television and Stage Achievement
Although she was offered major roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her movie career was stagnating and that TV would be the solution. Before going in a new direction, she won praise on Broadway in For Love or Money (1947), a comedy for which she won a Tony award as most promising 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 appeared regularly in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic workload continued for the following five decades, with a recurring role in General Hospital between 1984 and 1998. Among her many guest appearances were as herself in a 1988 episode of a comedy series, where the host finds a lost collie, and in another sitcom in 1995 as the mother of a dining manager.
Final Roles and Achievements
Her last 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 big screen version featuring well-known actors (1998), she had a digital cameo as a school principal. She took joy in learning how much of an inspiration the first series had been to future astronauts, and often participated in the organization’s launches and other events. In 2013 her work as a unpaid spokesperson brought her its Exceptional Public Achievement Medal.
Among her limited later feature films was the fantasy, Troll (1986) in which she portrayed a sorceress, with her own daughter, Anne Lockhart, playing her younger self.
Personal Details
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 second marriage, to John Lindsay, an architect.
She is remembered by her children and four grandkids.
