Launching her career in films, June Lockhart, who died aged 100, achieved her biggest success after shifting largely to television. Having been offered limited opportunities to excel in films from her debut as a child in 1938 until 1947, she excelled on TV in numerous popular series, especially in Lassie.
Her Memorable Role in Lassie
Stepping in from another actress in 1958, Lockhart continued in the show until 1964. Her role was Ruth Martin, wed to agriculturalist Paul Martin and the adoptive mother of young Timmy Martin, whose collie was the eponymous star of the series.
Even with playing a housewife, Lockhart skillfully avoided being overshadowed by the smart dog. She characterized the show as “a fantasy about families 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 show, Lockhart commented: “In six sexless years of playing a rural wife and mother, I was rarely allowed to peck my on-screen husband on the cheek.”
Featuring in Lost in Space
Lockhart went directly into another successful series, Lost in Space (1965-68), a semi-spoof sci-fi series aimed mostly at young audiences and based by The Swiss Family Robinson. Lockhart and another actor portrayed Maureen and John Robinson, two scientists investigating distant planets. Lockhart had to spend the majority of her time skillfully trying to navigate special effects. As the series progressed, the narrative became less and less about this interstellar family and increasingly about the young son and his friendship with a robot, and the timid antagonist Dr Zachary Smith.
Early Career and Family Influence
Lockhart’s movie debut, at the young 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 actual parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canada-native Gene were both actors in dozens of films, as well as on stage, it was nearly inevitable that June, who was born in New York, would join show business.
Her first stage appearance, at the tender age of six, came in a non-singing role in an musical production at the Metropolitan Opera in New York (1931).
Move to Hollywood and Film Roles
When her father was offered a deal by a motion picture studio, after his acclaim on Broadway, she moved with her family to Hollywood, where Gene made around 300 films. After attending school in Beverly Hills, June started her professional life in movies, mainly in small 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 charming as a New Yorker at a family party, whose dance card is filled maliciously to stop Lockhart interacting with her sibling.
More importantly, although she did not realize it at the time, was Son of Lassie (1945). It was one of multiple follow-ups to the extremely successful Lassie Come Home (1943), in which another actress had played the girl who helps the canine to escape to the family. In the later film, Lockhart played the now adult version.
The affectionate way in which she interacted with both Lassie and her son, Laddie, hero of a World War II adventure in Nazi-occupied 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 Success
Although she was offered leading roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her movie career was stagnating and that TV would be the solution. Before embarking in a new direction, she received praise on Broadway in For Love or Money (1947), a humorous play for which she won a Tony award as best newcomer.
A further substantial run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a physician and mother figure. She also featured regularly in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic schedule continued for the next five decades, with a recurring role in General Hospital between 1984 and 1998. Among her many guest appearances were as the actress in a 1988 episode of a comedy series, where the host finds a stray collie, and in another sitcom in 1995 as the mother of a dining manager.
Final Career and Impact
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 starring well-known actors (1998), she had a digital cameo as a school principal. She took pleasure in learning how much of an inspiration the original series had been to future astronauts, and often participated in the agency’s launches and other events. In 2013 her work as a unpaid spokesperson brought her its Exceptional Public Achievement Medal.
Among her few later feature films was the fantasy, Troll (1986) in which she portrayed a sorceress, with her own daughter, Anne Lockhart, playing her younger self.
Private Details
In 1951 she married John Maloney, a physician and former Navy medical officer. In addition to Anne, they had a second daughter, June. That union ended in divorce, as did her second marriage, to John Lindsay, an designer.
She is remembered by her daughters and four grandkids.
