Starting her career in cinema, June Lockhart, who died aged 100, achieved her greatest success after shifting largely to the small screen. Having been given few opportunities to shine in movies from her debut as a youngster in 1938 until 1947, she excelled on television in many beloved series, especially in Lassie.
Her Iconic Role in Lassie
Taking over from another actress in 1958, Lockhart continued in the series until 1964. Her role was Ruth Martin, wed to farmer Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose dog was the eponymous star of the series.
In her part as a homemaker, Lockhart somehow managed to avoid being totally overshadowed by the intelligent canine. She described the show as “a fairy tale about people on a farm in which the canine resolves all the problems in 22 minutes, in time for the last commercial”. After she left the series, Lockhart remarked: “In six sexless years of playing a rural wife and parent, I was hardly ever permitted to peck my on-screen husband on the cheek.”
Adventure into Lost in Space
Lockhart went directly into another successful series, Lost in Space (1965-68), a partly comedic science fiction series aimed primarily at children and based by The Swiss Family Robinson. Lockhart and her co-star portrayed Maureen and John Robinson, two scientists exploring alien planets. Lockhart had to spend the majority of her time skillfully trying to survive special effects. As the series progressed, the narrative became increasingly less about this space family and more about the boy and his bond with a mechanical being, and the timid villain Dr Zachary Smith.
Early Career and Family Background
Lockhart’s feature film first role, 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 British-born Kathleen and Canada-native Gene were both actors in dozens of films, as well as on stage, it was nearly inevitable that June, who was born in New York, would join the entertainment industry.
Her first stage appearance, at the tender age of six, came in a non-musical role in an opera at the Metropolitan Opera in New York (1931).
Move to Hollywood and Movie Roles
When her father was given a deal by a motion picture studio, after his acclaim on Broadway, she moved with her parents to Hollywood, where Gene made around 300 films. After going to school in Beverly Hills, June began her career in films, 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 last one, she is delightful as a New Yorker at a household party, whose schedule is arranged maliciously to stop Lockhart dancing 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 another actress had played the girl who helps the canine to return to the family. In the subsequent film, Lockhart played the now grown-up version.
The loving way in which she handled both Lassie and her offspring, Laddie, hero of a wartime adventure in Nazi-occupied Norway, was in the minds of the creators when it came to casting the Lassie TV series 13 years later.
TV and Theater Work
Although she was given 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 television would be the solution. Before embarking in a new direction, she won praise on Broadway in For Love or Money (1947), a humorous play for which she won a Tony award as most promising newcomer.
A additional significant run came with Petticoat Junction (1968-70), set in a country 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 next 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 mother of a restaurant manager.
Final Roles and Contributions
Her final 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 movie version starring famous actors (1998), she had a digital cameo as a school principal. She took pleasure in learning how much of an influence the original series had been to future astronauts, and often attended 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 sorceress, with her own daughter, Anne Lockhart, playing her earlier self.
Private Details
In 1951 she wed John Maloney, a doctor and former Navy doctor. In addition to Anne, they had another daughter, June. That marriage ended in separation, as did her subsequent marriage, to John Lindsay, an designer.
She is remembered by her daughters and four grandchildren.
