Starting her career in films, June Lockhart, who passed on aged 100, achieved her greatest success after switching predominantly to television. Having been offered few opportunities to excel in films from her first appearance as a youngster in 1938 until 1947, she thrived on television in many beloved series, most notably in Lassie.
Her Iconic Role in Lassie
Stepping in from a previous star in 1958, Lockhart remained in the series until 1964. Her role was Ruth Martin, married to farmer Paul Martin and the foster mother of seven-year-old Timmy Martin, whose dog was the eponymous star of the series.
In her role as a housewife, Lockhart somehow succeeded to avoid being completely upstaged by the clever dog. She described the show as “a fairy tale about people on a rural property in which the canine solves all the issues in 22 minutes, in time for the last advertisement”. After she left the show, Lockhart commented: “In six chaste years of playing a country spouse and parent, I was hardly ever allowed to peck my on-screen husband on the face.”
Featuring in Lost in Space
Lockhart went directly into a second successful series, Lost in Space (1965-68), a partly comedic science fiction series aimed primarily at young audiences and based by The Swiss Family Robinson. Lockhart and another actor portrayed Maureen and John Robinson, two researchers 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 space family and increasingly about the young son and his friendship with a robot, and the cowardly antagonist Dr Zachary Smith.
Beginnings in Show Business
Lockhart’s movie first role, at the age of 13, had come as Belinda Cratchit in A Christmas Carol (1938). In the roles of her mother and father, Bob and Mrs Cratchit, were her real-life parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canada-native Gene were both performers in many of films, as well as on theater, it was almost inevitable 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-musical role in an opera at the Metropolitan Opera in New York (1931).
Move to Hollywood and Movie Roles
When her parent was offered 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 started her career in movies, 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 last one, she is charming as a New Yorker at a household party, whose dance card is filled maliciously to prevent Lockhart interacting with her sibling.
More significantly, although she did not know it at the time, was Son of Lassie (1945). It was one of several follow-ups to the hugely 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 grown-up version.
The affectionate way in which she handled both Lassie and her offspring, Laddie, hero of a World War II adventure in enemy-held Norway, was in the consideration of the creators when it came to casting the Lassie TV series 13 years later.
Transition to Television and Broadway Success
Although she was given leading roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her film career was getting her nowhere and that television would be the solution. Before going in a new direction, she received praise on Broadway in For Love or Money (1947), a comedy for which she won a Tony award as best newcomer.
A additional significant run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a physician and maternal character. She also appeared 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 next five decades, with a regular role in General Hospital between 1984 and 1998. Among her many guest 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 Contributions
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 movie version featuring well-known actors (1998), she had a holographic cameo as a school principal. She took joy in learning how much of an influence the original series had been to later astronauts, and often participated in the organization’s launches and other events. In 2013 her work as a unpaid representative brought her its Exceptional Public Achievement Medal.
Among her limited later 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 wed John Maloney, a doctor and former Navy doctor. 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 survived by her daughters and four grandchildren.
