Starting her career in films, June Lockhart, who died aged 100, found her biggest success after shifting largely to television. Having been given few chances to shine in films from her first appearance as a child in 1938 until 1947, she excelled on TV in numerous popular series, most notably in Lassie.
Portraying Ruth Martin on Lassie
Stepping in from a previous star in 1958, Lockhart remained in the series 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.
Even with playing a housewife, Lockhart skillfully avoided being outshone by the brilliant dog. She described the program as “a fantasy about people on a rural property in which the canine resolves all the issues in 22 minutes, in time for the last commercial”. After she departed the series, Lockhart remarked: “In six sexless years of playing a country wife and mother, I was rarely permitted to kiss my on-screen husband on the face.”
Adventure into Lost in Space
Lockhart went straight into a second hit, Lost in Space (1965-68), a semi-spoof science fiction series targeted primarily at young audiences and inspired by The Swiss Family Robinson. Lockhart and her co-star played Maureen and John Robinson, two scientists investigating alien planets. Lockhart had to spend the majority of her time skillfully trying to navigate special effects. As the series progressed, the narrative became increasingly less about this interstellar clan and more about the young son and his bond with a mechanical being, and the timid villain Dr Zachary Smith.
Beginnings in Show Business
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 performers in dozens of movies, as well as on theater, it was nearly certain that June, who was born in New York, would enter show business.
Her first theatrical appearance, at the tender age of six, came in a non-musical role in an musical production at the Metropolitan Opera in New York (1931).
Hollywood Work
When her father was given a contract by a film studio, after his acclaim on Broadway, she moved with her family to Hollywood, where Gene made around 300 films. After going to school in Beverly Hills, June began her professional life in films, mostly in small 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 charming 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 know it at the time, was Son of Lassie (1945). It was one of multiple sequels to the extremely successful Lassie Come Home (1943), in which a young star had played the girl who assists the canine to return to the family. In the subsequent film, Lockhart played the now grown-up character.
The affectionate 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 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 thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her movie career was stagnating and that TV would be the answer. Before going 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 best newcomer.
A further significant run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a doctor 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 workload persisted 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 host finds a stray collie, and in another sitcom in 1995 as the parent of a dining manager.
Later Roles and Contributions
Her final TV appearance 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 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 organization’s launches and other events. In 2013 her work as a volunteer spokesperson brought her its Exceptional Public Achievement Medal.
Among her limited subsequent feature films was the fantasy, Troll (1986) in which she portrayed a sorceress, with her own daughter, Anne Lockhart, playing her earlier self.
Personal Information
In 1951 she wed John Maloney, a doctor 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 remembered by her daughters and four grandchildren.
