Launching her career in films, June Lockhart, who died aged 100, achieved her biggest success after switching largely to the small screen. Having been offered limited opportunities to excel in films from her first appearance as a child in 1938 until 1947, she thrived on TV in many popular series, especially in Lassie.
Portraying Ruth Martin on Lassie
Taking over from a previous star 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 collie was the eponymous star of the series.
Even with playing a mother figure, Lockhart skillfully avoided being outshone by the brilliant dog. She characterized the program as “a fantasy about people on a farm in which the canine resolves all the issues in 22 minutes, in time for the last commercial”. After she left the show, Lockhart commented: “In six chaste years of playing a country wife and mother, I was rarely permitted to peck my co-star on the face.”
Starring in Lost in Space
Lockhart went directly into another hit, Lost in Space (1965-68), a partly comedic science fiction series targeted primarily at young audiences and inspired by The Swiss Family Robinson. Lockhart and her co-star portrayed Maureen and John Robinson, two researchers investigating alien planets. Lockhart had to spend the majority of her time skillfully trying to survive visual effects. As the show progressed, the storyline became increasingly less about this interstellar family and more about the young son and his friendship with a robot, and the cowardly antagonist Dr Zachary Smith.
Early Career and Family Background
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 real-life parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canada-native Gene were both performers in many of movies, as well as on stage, it was almost certain that June, who was born in New York, would enter the entertainment industry.
Her first stage appearance, at the 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 deal by a motion picture studio, after his acclaim on Broadway, she moved with her family to Hollywood, where Gene made approximately 300 films. After going to school in Beverly Hills, June started her career in films, 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 schedule is arranged spitefully to prevent 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 multiple sequels to the hugely successful Lassie Come Home (1943), in which another actress had played the female character who helps the canine to return to the family. In the later film, Lockhart played the now adult character.
The affectionate way in which she handled both Lassie and her offspring, Laddie, hero of a wartime story in enemy-held Norway, was in the minds of the producers when it came to selecting the Lassie TV series 13 years later.
TV and Theater Work
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 television 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 additional significant run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a doctor and maternal character. She also appeared frequently in TV westerns 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 one-off appearances were as herself 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 Career and Legacy
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 movie version featuring well-known actors (1998), she had a holographic cameo as a school principal. She took pleasure in learning how much of an influence the first series had been to future 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 later feature films was the fantasy, Troll (1986) in which she portrayed a witch, with her own daughter, Anne Lockhart, playing her earlier self.
Personal Life and Family
In 1951 she wed John Maloney, a physician and former Navy medical officer. In addition to Anne, they had a second daughter, June. That union ended in separation, as did her second marriage, to John Lindsay, an designer.
She is remembered by her children and four grandkids.
