June Lockhart, who died at the age of 100, began her career in movies, but achieved fame after moving almost exclusively to TV. Having been given limited chances to excel in films from her debut as a youngster in 1938 until 1947, she thrived on television in many beloved series, most notably in Lassie.
Her Memorable Role in Lassie
Taking over from a previous star in 1958, Lockhart continued in the show until 1964. She played Ruth Martin, wed to farmer Paul Martin and the foster mother of young Timmy Martin, whose collie was the titular star of the series.
Despite playing a mother figure, Lockhart skillfully avoided being outshone by the brilliant animal star. She described the program as “a fairy tale about people on a rural property in which the canine resolves all the problems in 22 minutes, in time for the last advertisement”. After she left the series, Lockhart remarked: “In six sexless years of playing a rural spouse and parent, I was rarely permitted to peck my on-screen husband on the cheek.”
Starring in Lost in Space
Lockhart went directly into another hit, Lost in Space (1965-68), a semi-spoof sci-fi series targeted mostly at children and based by The Swiss Family Robinson. Lockhart and her co-star played Maureen and John Robinson, two scientists exploring alien planets. Lockhart had to spend the majority of her time skillfully trying to navigate visual effects. As the show progressed, the storyline became less and less about this interstellar family and increasingly about the boy and his friendship with a mechanical being, 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 parents, Bob and Mrs Cratchit, were her real-life parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canadian-born Gene were both actors in dozens of films, as well as on theater, it was almost inevitable that June, who was born in New York, would enter the entertainment industry.
Her first theatrical appearance, at the tender age of six, came in a non-singing role in an opera at the Metropolitan Opera in New York (1931).
Hollywood Work
When her father was given a deal by a motion picture studio, after his success on Broadway, she moved with her parents to Hollywood, where Gene made approximately 300 films. After attending school in Beverly Hills, June began her career in films, mainly 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 delightful as a New Yorker at a household party, whose dance card is arranged spitefully to prevent Lockhart interacting with her brother.
More importantly, although she did not realize 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 a young star had played the girl who assists the dog to return to the owners. In the later film, Lockhart played the now adult character.
The affectionate way in which she interacted with both Lassie and her offspring, Laddie, hero of a wartime story in enemy-held Norway, was in the consideration of the producers when it came to casting the Lassie TV series 13 years later.
TV and Theater Career
Although she was offered major 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 solution. Before going in a new direction, she received acclaim on Broadway in For Love or Money (1947), a comedy for which she won a Tony award as most promising newcomer.
A further substantial 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 hectic schedule persisted for the following 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 talkshow, where the presenter finds a lost collie, and in another sitcom in 1995 as the mother of a dining manager.
Later Roles and Achievements
Her final TV credit came in 2021 as the narration of Alpha Control in an episode of a streaming service’s new version of Lost in Space. In the big screen version starring well-known 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 organization’s launches and other events. In 2013 her work as a volunteer representative brought her its Exceptional Public Achievement Medal.
Among her limited subsequent feature films was the fantasy, Troll (1986) in which she played a sorceress, with her own daughter, Anne Lockhart, playing her earlier self.
Personal Information
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 second marriage, to John Lindsay, an designer.
She is remembered by her children and four grandkids.
