June Lockhart, who died at the remarkable age of 100, started her professional journey in movies, but gained recognition after transitioning almost entirely to television. Having been offered limited opportunities to excel in movies from her first appearance as a youngster in 1938 until 1947, she thrived on TV in many popular series, especially in Lassie.
Her Iconic Role in Lassie
Stepping in from another actress in 1958, Lockhart continued in the show until 1964. Her role was Ruth Martin, wed to agriculturalist Paul Martin and the foster mother of seven-year-old Timmy Martin, whose dog was the eponymous star of the series.
Despite playing a housewife, Lockhart adeptly avoided being overshadowed by the brilliant animal star. She characterized the program as “a fairy tale about people on a rural property in which the dog solves all the problems in 22 minutes, in time for the last advertisement”. After she departed the show, Lockhart commented: “In six sexless years of playing a rural spouse and parent, I was rarely allowed to peck my on-screen husband on the face.”
Starring in Lost in Space
Lockhart went straight into a second hit, Lost in Space (1965-68), a semi-spoof sci-fi series aimed primarily at children and based by The Swiss Family Robinson. Lockhart and her co-star played Maureen and John Robinson, two scientists exploring distant planets. Lockhart had to spend the majority of her time skillfully trying to navigate special effects. As the series progressed, the storyline became less and less about this space clan and more about the boy and his bond with a mechanical being, and the cowardly antagonist Dr Zachary Smith.
Early Career and Family Influence
Lockhart’s movie first role, at the young age of 13, had come as Belinda Cratchit in A Christmas Carol (1938). In the parts of her mother and father, 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 theater, it was almost certain that June, who was born in New York, would join show business.
Her first theatrical performance, at the tender age of six, came in a non-singing role in an musical production at the Metropolitan Opera in New York (1931).
Cinema Work
When her father was given a contract by a film studio, after his success on Broadway, she relocated with her family to Hollywood, where Gene made around 300 films. After going to school in Beverly Hills, June began her professional life in movies, mostly 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 charming as a New Yorker at a family party, whose dance card is filled maliciously to stop Lockhart dancing with her sibling.
More significantly, although she did not know 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 affectionate way in which she handled both Lassie and her offspring, Laddie, hero of a wartime adventure 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 Stage Career
Although she was offered 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 answer. Before embarking in a new direction, she received praise 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 physician and mother figure. She also featured frequently in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy schedule persisted for the next 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 mother of a dining manager.
Final Career and Legacy
Her final TV appearance came in 2021 as the narration 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 holographic 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 volunteer spokesperson brought her its Exceptional Public Achievement Medal.
Among her few 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 Life and Family
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 subsequent marriage, to John Lindsay, an architect.
She is remembered by her children and four grandchildren.
