June Lockhart, who passed away at the remarkable age of 100, started her career in movies, but gained recognition after moving almost entirely to television. Having been given limited opportunities to excel in movies from her debut as a youngster in 1938 until 1947, she thrived on television in many beloved series, most notably in Lassie.
Portraying Ruth Martin on Lassie
Taking over from another actress in 1958, Lockhart remained in the series until 1964. Her role was Ruth Martin, married to farmer Paul Martin and the foster mother of young Timmy Martin, whose dog was the eponymous hero of the series.
In her part as a homemaker, Lockhart somehow succeeded to avoid being totally overshadowed by the clever canine. She characterized the program as “a fairy tale about families on a farm in which the dog resolves all the problems in 22 minutes, in time for the last advertisement”. After she left the show, Lockhart remarked: “In six chaste years of playing a country spouse and mother, I was hardly ever permitted to peck my co-star on the face.”
Adventure into Lost in Space
Lockhart went directly into a second hit, Lost in Space (1965-68), a partly comedic sci-fi series targeted mostly at young audiences and inspired by The Swiss Family Robinson. Lockhart and her co-star portrayed Maureen and John Robinson, two researchers exploring alien planets. Lockhart had to spend most of her time deftly trying to survive special effects. As the show progressed, the storyline became less and less about this space family and more about the young son and his friendship with a robot, and the cowardly villain Dr Zachary Smith.
Start in Entertainment
Lockhart’s feature film debut, at the 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 UK-native Kathleen and Canadian-born 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 join the entertainment industry.
Her first theatrical appearance, at the age of six, came in a non-musical role in an opera at the Metropolitan Opera in New York (1931).
Cinema Work
When her father was offered a contract by a film studio, after his success on Broadway, she relocated with her parents to Hollywood, where Gene made around 300 films. After attending school in Beverly Hills, June began her career in movies, 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 charming as a New Yorker at a family party, whose schedule is arranged spitefully to stop Lockhart dancing with her sibling.
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 girl who helps the canine to return to the owners. In the subsequent film, Lockhart played the now adult character.
The affectionate way in which she interacted with both Lassie and her offspring, Laddie, hero of a World War II story in Nazi-occupied Norway, was in the consideration of the producers when it came to selecting the Lassie TV series 13 years later.
Transition to Television and Stage Achievement
Although she was given major roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her film career was getting her nowhere and that television would be the solution. Before going in a new direction, she received 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 physician and mother figure. She also appeared regularly in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic schedule persisted 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 talkshow, where the presenter finds a lost collie, and in another sitcom in 1995 as the parent of a restaurant manager.
Final Roles and Contributions
Her last TV credit 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 featuring well-known actors (1998), she had a digital cameo as a school principal. She took pleasure in learning how much of an inspiration the original series had been to future astronauts, and often attended the agency’s launches and other events. In 2013 her work as a volunteer representative brought her its Exceptional Public Achievement Medal.
Among her limited later feature films was the fantasy, Troll (1986) in which she portrayed a sorceress, with her own daughter, Anne Lockhart, playing her earlier self.
Personal Life and Family
In 1951 she wed John Maloney, a doctor and former Navy doctor. In addition to Anne, they had another daughter, June. That union ended in divorce, as did her second marriage, to John Lindsay, an architect.
She is remembered by her children and four grandkids.
