June Lockhart, who died at the age of 100, began her career in movies, but achieved fame after transitioning almost exclusively to TV. Having been given few opportunities to shine in movies from her debut as a child in 1938 until 1947, she excelled on TV in numerous beloved series, especially in Lassie.
Her Iconic Role in Lassie
Stepping in from a previous star in 1958, Lockhart continued in the show until 1964. She played Ruth Martin, wed to farmer Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose collie was the eponymous star of the series.
Despite playing a mother figure, Lockhart adeptly avoided being overshadowed by the smart dog. She described the program as “a fantasy about people on a rural property in which the canine resolves all the issues in 22 minutes, in time for the last advertisement”. After she departed the series, Lockhart commented: “In six sexless years of playing a rural wife and parent, I was hardly ever allowed to peck my co-star on the cheek.”
Journey into Lost in Space
Lockhart went straight into another successful series, Lost in Space (1965-68), a semi-spoof sci-fi series targeted primarily at young audiences and inspired by The Swiss Family Robinson. Lockhart and another actor portrayed Maureen and John Robinson, two researchers exploring alien planets. Lockhart had to spend most of her time skillfully trying to survive special effects. As the series continued, the storyline became increasingly less about this space family and more about the young son and his bond with a robot, and the cowardly villain Dr Zachary Smith.
Early Career and Family Influence
Lockhart’s movie 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 real-life 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 nearly certain that June, who was born in New York, would enter the entertainment industry.
Her first theatrical performance, at the age of six, came in a non-musical role in an musical production at the Metropolitan Opera in New York (1931).
Cinema 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 going to school in Beverly Hills, June began her career in films, mostly in minor roles in prestigious 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 family party, whose dance card is arranged spitefully to stop 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 multiple follow-ups to the hugely successful Lassie Come Home (1943), in which another actress had played the girl who helps the dog to return to the owners. In the subsequent film, Lockhart played the now adult version.
The loving way in which she handled both Lassie and her offspring, Laddie, hero of a wartime adventure in enemy-held 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 given leading roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her film career was stagnating and that TV would be the solution. 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 substantial run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a physician and mother figure. She also appeared regularly in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy 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 herself in a 1988 episode of a comedy series, where the host finds a lost collie, and in another sitcom in 1995 as the parent of a dining manager.
Final Career and Impact
Her final TV appearance 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 famous 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 future astronauts, and often attended the organization’s launches and other events. In 2013 her work as a unpaid representative brought her its Exceptional Public Achievement Medal.
Among her few subsequent feature films was the fantasy, Troll (1986) in which she played 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 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 architect.
She is survived by her children and four grandkids.
