June Lockhart, who died at the age of 100, started her career in films, but gained recognition after moving almost entirely to television. Having been given few opportunities to shine in films from her debut as a child in 1938 until 1947, she excelled on television in numerous beloved series, especially in Lassie.
Portraying Ruth Martin on Lassie
Stepping in from a previous star in 1958, Lockhart continued in the series until 1964. She played Ruth Martin, married to agriculturalist Paul Martin and the foster mother of young Timmy Martin, whose dog was the eponymous star of the series.
Despite playing a mother figure, Lockhart adeptly avoided being overshadowed by the brilliant dog. She characterized the program as “a fantasy about people on a farm in which the dog solves all the problems in 22 minutes, in time for the last advertisement”. After she departed the show, Lockhart commented: “In six chaste years of playing a rural wife and parent, I was hardly ever allowed to kiss my co-star on the cheek.”
Starring in Lost in Space
Lockhart went directly into a second hit, Lost in Space (1965-68), a semi-spoof science fiction series aimed mostly at young audiences and inspired by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two researchers investigating distant planets. Lockhart had to spend most of her time deftly trying to navigate special effects. As the series continued, the storyline became increasingly less about this interstellar family and more about the young son and his bond with a mechanical being, and the cowardly antagonist Dr Zachary Smith.
Initial 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 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 the entertainment industry.
Her first stage appearance, at the tender age of six, came in a non-musical role in an musical production at the Metropolitan Opera in New York (1931).
Hollywood Career
When her parent was offered a deal by a film studio, after his acclaim on Broadway, she moved with her family to Hollywood, where Gene made around 300 films. After going to school in Beverly Hills, June began her career in films, mostly in small 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 delightful as a New Yorker at a family party, whose schedule is filled maliciously to prevent Lockhart dancing with her sibling.
More significantly, although she did not realize it at the time, was Son of Lassie (1945). It was one of several follow-ups to the extremely successful Lassie Come Home (1943), in which another actress had played the girl who helps the canine to return to the owners. In the subsequent film, Lockhart played the now adult version.
The affectionate way in which she interacted with both Lassie and her son, Laddie, hero of a wartime story in enemy-held Norway, was in the consideration of the producers when it came to selecting the Lassie TV series 13 years later.
Shift to Television and Stage Achievement
Although she was offered major roles in two thrillers, 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 embarking in a new direction, she won acclaim on Broadway in For Love or Money (1947), a comedy 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 appeared regularly in TV cowboy shows 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 comedy series, where the presenter finds a stray collie, and in another sitcom in 1995 as the parent 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 remake of Lost in Space. In the movie version featuring famous 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 volunteer spokesperson brought her its Exceptional Public Achievement Medal.
Among her few later feature films was the fantasy, Troll (1986) in which she played a sorceress, 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 marriage ended in divorce, as did her second marriage, to John Lindsay, an designer.
She is survived by her children and four grandkids.
