June Lockhart, who died at the age of 100, started her career in films, but gained fame after moving almost exclusively to TV. Having been given few opportunities to excel in movies from her debut as a child in 1938 until 1947, she excelled on television in many beloved series, especially in Lassie.
Portraying Ruth Martin on Lassie
Stepping in from another actress in 1958, Lockhart remained in the series until 1964. Her role was Ruth Martin, wed to agriculturalist Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose collie was the titular star of the series.
Even with playing a mother figure, Lockhart adeptly avoided being outshone by the brilliant animal star. She described the program as “a fairy tale about people on a farm in which the canine solves all the problems in 22 minutes, in time for the last commercial”. After she departed the series, Lockhart commented: “In six sexless years of playing a country wife and parent, I was hardly ever allowed to kiss my co-star on the face.”
Adventure into Lost in Space
Lockhart went directly into another hit, Lost in Space (1965-68), a partly comedic science fiction series targeted primarily at children and based by The Swiss Family Robinson. Lockhart and her co-star portrayed Maureen and John Robinson, two scientists investigating alien planets. Lockhart had to spend the majority of her time skillfully trying to survive special effects. As the series progressed, the storyline became less and less about this interstellar clan and increasingly about the boy and his bond with a mechanical being, and the timid antagonist Dr Zachary Smith.
Initial Career and Family Influence
Lockhart’s feature film debut, at the young age of 13, had come as Belinda Cratchit in A Christmas Carol (1938). In the parts of her parents, Bob and Mrs Cratchit, were her actual parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canada-native Gene were both actors in dozens of movies, as well as on stage, it was almost inevitable that June, who was born in New York, would join show business.
Her first stage performance, at the age of six, came in a non-musical role in an opera at the Metropolitan Opera in New York (1931).
Cinema Career
When her father was given a contract by a film studio, after his acclaim on Broadway, she relocated with her family to Hollywood, where Gene made approximately 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 household party, whose schedule is arranged spitefully to stop Lockhart dancing with her brother.
More significantly, 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 female character who assists the canine to return to the owners. In the later film, Lockhart played the now adult character.
The loving 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 minds of the creators when it came to casting the Lassie TV series 13 years later.
TV and Theater 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 getting her nowhere and that TV would be the answer. Before going in a different direction, she received 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 rural hotel, where Lockhart is a doctor and maternal character. She also featured frequently in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy workload continued for the next five decades, with a regular 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 host finds a lost collie, and in another sitcom in 1995 as the mother of a dining manager.
Later Roles and Contributions
Her final TV credit came in 2021 as the voice of Alpha Control in an episode of a streaming service’s remake of Lost in Space. In the big screen version featuring well-known actors (1998), she had a holographic cameo as a school principal. She took pleasure 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 representative brought her its prestigious award.
Among her limited subsequent feature films was the fantasy, Troll (1986) in which she portrayed a witch, with her own daughter, Anne Lockhart, playing her younger self.
Personal Life and Family
In 1951 she married John Maloney, a doctor and former Navy medical officer. In addition to Anne, they had a second daughter, June. That union ended in separation, as did her subsequent marriage, to John Lindsay, an architect.
She is survived by her children and four grandchildren.
