June Lockhart, who passed away at the remarkable age of 100, began her professional journey in films, but gained fame after moving almost entirely to television. Having been offered limited chances to shine in films from her debut as a youngster in 1938 until 1947, she excelled on television in numerous beloved series, most notably in Lassie.
Her Memorable Role in Lassie
Taking over from another actress in 1958, Lockhart remained in the show until 1964. Her role was Ruth Martin, married to agriculturalist Paul Martin and the foster mother of young Timmy Martin, whose dog was the eponymous hero of the series.
Even with playing a mother figure, Lockhart adeptly avoided being outshone by the smart animal star. She described the program as “a fairy tale about people on a rural property in which the dog resolves all the problems in 22 minutes, in time for the last advertisement”. After she left the show, Lockhart remarked: “In six chaste years of playing a country wife and parent, I was rarely permitted to peck my co-star on the cheek.”
Featuring in Lost in Space
Lockhart went straight into another successful series, Lost in Space (1965-68), a semi-spoof sci-fi series targeted mostly at children and based by The Swiss Family Robinson. Lockhart and another actor portrayed Maureen and John Robinson, two researchers investigating distant planets. Lockhart had to spend the majority of her time skillfully trying to navigate visual effects. As the series continued, the narrative became increasingly less about this interstellar clan and increasingly about the boy and his bond 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 parts 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 performers in many of films, as well as on stage, it was nearly certain that June, who was born in New York, would join show business.
Her first stage performance, at the age of six, came in a non-singing role in an opera at the Metropolitan Opera in New York (1931).
Cinema Work
When her father was offered a deal by a film studio, after his acclaim on Broadway, she relocated with her family to Hollywood, where Gene made approximately 300 films. After going to school in Beverly Hills, June began her professional life in films, mainly 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 last one, she is charming as a New Yorker at a family party, whose dance card is arranged maliciously to stop Lockhart dancing with her sibling.
More importantly, although she did not know 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 helps the canine to escape to the family. In the later film, Lockhart played the now adult character.
The affectionate way in which she handled both Lassie and her son, Laddie, hero of a wartime adventure in enemy-held Norway, was in the consideration of the creators when it came to selecting the Lassie TV series 13 years later.
TV and Theater Work
Although she was given leading roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her film career was getting her nowhere and that television would be the solution. Before going in a different 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 featured regularly in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy schedule continued for the next 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.
Final Career and Impact
Her final TV appearance came in 2021 as the narration of Alpha Control in an episode of a digital platform’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 influence the first series had been to later astronauts, and often participated in 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 portrayed a witch, with her own daughter, Anne Lockhart, playing her younger self.
Personal Life and Family
In 1951 she wed John Maloney, a physician and former Navy medical officer. In addition to Anne, they had another daughter, June. That union ended in separation, as did her subsequent marriage, to John Lindsay, an architect.
She is survived by her daughters and four grandchildren.
