June Lockhart, who passed away at the remarkable age of 100, began her professional journey in movies, but gained fame after transitioning almost exclusively to TV. Having been offered few opportunities to shine in films from her debut as a youngster in 1938 until 1947, she thrived on TV in many popular series, most notably in Lassie.
Her Iconic Role in Lassie
Taking over from a previous star in 1958, Lockhart remained in the series until 1964. Her role was Ruth Martin, married to agriculturalist Paul Martin and the foster mother of young Timmy Martin, whose collie was the titular hero of the series.
Even with playing a mother figure, Lockhart adeptly avoided being outshone by the brilliant dog. She described the show as “a fairy tale about people on a rural property in which the canine solves all the issues in 22 minutes, in time for the last commercial”. After she departed the show, Lockhart remarked: “In six chaste years of playing a rural spouse and mother, I was hardly ever permitted to peck my co-star on the face.”
Adventure into Lost in Space
Lockhart went straight into a second hit, Lost in Space (1965-68), a partly comedic science fiction series targeted mostly at children and based by The Swiss Family Robinson. Lockhart and her co-star played Maureen and John Robinson, two scientists investigating alien planets. Lockhart had to spend most of her time deftly trying to survive special effects. As the series progressed, the storyline became increasingly less about this interstellar clan and more about the young son and his friendship with a mechanical being, and the timid antagonist Dr Zachary Smith.
Beginnings in Show Business
Lockhart’s feature film debut, 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 Canadian-born Gene were both actors in dozens of films, as well as on stage, it was almost certain that June, who was born in New York, would join the entertainment industry.
Her first stage performance, at the age of six, came in a non-musical role in an opera at the Metropolitan Opera in New York (1931).
Move to Hollywood and Film Roles
When her parent was given a deal by a motion picture studio, after his success on Broadway, she relocated with her family to Hollywood, where Gene made around 300 films. After attending school in Beverly Hills, June began her professional life in movies, 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 household party, whose dance card is filled 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 extremely successful Lassie Come Home (1943), in which a young star had played the female character who helps the canine to return to the owners. In the subsequent film, Lockhart played the now adult character.
The loving way in which she handled both Lassie and her son, Laddie, protagonist of a World War II story in Nazi-occupied Norway, was in the consideration of the creators when it came to selecting the Lassie TV series 13 years later.
Television and Theater Career
Although she was given leading roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her film career was stagnating and that television would be the solution. Before going in a different direction, she received praise on Broadway in For Love or Money (1947), a comedy 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 physician 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 schedule continued for the next 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 presenter finds a lost collie, and in another sitcom in 1995 as the mother of a dining manager.
Later Roles and Contributions
Her final TV credit came in 2021 as the voice of Alpha Control in an episode of a streaming service’s new version of Lost in Space. In the big screen version starring 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 later astronauts, and often attended the agency’s launches and other events. In 2013 her work as a unpaid representative brought her its Exceptional Public Achievement Medal.
Among her few subsequent feature films was the fantasy, Troll (1986) in which she played a sorceress, with her own daughter, Anne Lockhart, playing her younger self.
Private Information
In 1951 she wed John Maloney, a physician and former Navy medical officer. In addition to Anne, they had a second daughter, June. That marriage ended in separation, as did her subsequent marriage, to John Lindsay, an designer.
She is survived by her daughters and four grandchildren.
