June Lockhart, who passed away at the age of 100, began her career in films, but achieved recognition after transitioning almost exclusively to television. Having been offered limited opportunities to excel in movies from her first appearance as a youngster in 1938 until 1947, she excelled on television in numerous beloved series, especially in Lassie.
Her Memorable Role in Lassie
Taking over from another actress in 1958, Lockhart remained in the show until 1964. She played Ruth Martin, wed to agriculturalist Paul Martin and the foster mother of young Timmy Martin, whose collie was the titular hero of the series.
In her role as a homemaker, Lockhart somehow managed to avoid being totally overshadowed by the clever dog. She characterized the show as “a fairy tale about people on a farm in which the dog resolves 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 country wife and mother, I was hardly ever permitted to peck my on-screen husband on the cheek.”
Adventure into Lost in Space
Lockhart went straight into another successful series, Lost in Space (1965-68), a partly comedic sci-fi series aimed primarily at children and inspired by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two scientists investigating alien planets. Lockhart had to spend most of her time skillfully trying to survive visual effects. As the series continued, the narrative became increasingly less about this space family and more about the young son and his friendship with a robot, and the cowardly antagonist Dr Zachary Smith.
Early Career and Family Background
Lockhart’s feature film first role, at the young age of 13, had come as Belinda Cratchit in A Christmas Carol (1938). In the roles of her parents, Bob and Mrs Cratchit, were her actual parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canadian-born Gene were both performers in many of films, as well as on stage, it was nearly 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-singing role in an musical production at the Metropolitan Opera in New York (1931).
Cinema Work
When her parent was given a deal by a motion picture studio, after his success on Broadway, she moved with her family to Hollywood, where Gene made around 300 films. After attending school in Beverly Hills, June began her career in films, mainly 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 latter, she is delightful as a New Yorker at a family party, whose dance card is filled maliciously to prevent Lockhart interacting with her brother.
More significantly, although she did not realize it at the time, was Son of Lassie (1945). It was one of multiple sequels to the extremely successful Lassie Come Home (1943), in which a young star had played the female character who helps the dog to return to the family. In the later film, Lockhart played the now grown-up character.
The affectionate way in which she interacted with both Lassie and her son, Laddie, protagonist of a wartime story in Nazi-occupied Norway, was in the minds of the creators when it came to casting the Lassie TV series 13 years later.
Television and Theater Work
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 answer. Before embarking 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 rural hotel, where Lockhart is a physician and maternal character. She also appeared frequently in TV cowboy shows 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 recurring 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 mother of a restaurant manager.
Final Roles and Achievements
Her final TV appearance came in 2021 as the voice of Alpha Control in an episode of a digital platform’s remake 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 first series had been to future astronauts, and often participated in the agency’s launches and other events. In 2013 her work as a unpaid representative brought her its prestigious award.
Among her few subsequent feature films was the fantasy, Troll (1986) in which she portrayed a sorceress, with her own daughter, Anne Lockhart, playing her earlier self.
Private Details
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 separation, as did her second marriage, to John Lindsay, an designer.
She is survived by her children and four grandchildren.
