June Lockhart, who died at the remarkable age of 100, began her professional journey in movies, but achieved recognition after moving almost exclusively to television. Having been offered limited opportunities to shine in films from her debut as a youngster in 1938 until 1947, she excelled on television in numerous beloved series, especially in Lassie.
Her Iconic Role in Lassie
Taking over from another actress in 1958, Lockhart remained in the series until 1964. Her role was Ruth Martin, wed to farmer Paul Martin and the foster mother of seven-year-old Timmy Martin, whose collie was the eponymous hero of the series.
In her part as a homemaker, Lockhart somehow succeeded to avoid being completely overshadowed by the intelligent canine. She characterized the show as “a fantasy about families on a farm in which the canine solves all the issues in 22 minutes, in time for the last commercial”. After she left the show, Lockhart commented: “In six chaste years of playing a rural wife and parent, I was rarely allowed to peck my co-star on the face.”
Starring in Lost in Space
Lockhart went straight into a second successful series, Lost in Space (1965-68), a semi-spoof sci-fi series targeted primarily at children and inspired by The Swiss Family Robinson. Lockhart and her co-star portrayed Maureen and John Robinson, two scientists investigating distant planets. Lockhart had to spend most of her time deftly trying to navigate visual effects. As the show continued, the storyline became increasingly less about this space clan and more about the boy and his bond with a robot, and the timid antagonist Dr Zachary Smith.
Early Career and Family Influence
Lockhart’s feature film 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 Canada-native Gene were both actors in dozens of movies, as well as on theater, it was nearly inevitable 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 opera at the Metropolitan Opera in New York (1931).
Move to Hollywood and Movie Roles
When her parent was offered a contract by a film studio, after his success on Broadway, she relocated with her family to Hollywood, where Gene made approximately 300 films. After attending school in Beverly Hills, June started 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 charming as a New Yorker at a family party, whose dance card is filled maliciously to stop 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 multiple sequels to the extremely successful Lassie Come Home (1943), in which a young star had played the female character who assists the canine to return to the family. In the subsequent film, Lockhart played the now grown-up character.
The loving way in which she interacted with both Lassie and her son, Laddie, protagonist of a World War II story in enemy-held Norway, was in the consideration of the creators when it came to selecting the Lassie TV series 13 years later.
Transition to Television and Broadway Achievement
Although she was offered major roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her movie career was getting her nowhere and that TV would be the answer. Before going in a different direction, she won praise on Broadway in For Love or Money (1947), a humorous play for which she won a Tony award as most promising newcomer.
A further substantial run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a doctor and mother figure. She also featured frequently in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic schedule continued for the following five decades, with a recurring role in General Hospital between 1984 and 1998. Among her many guest appearances were as herself 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 restaurant manager.
Final Roles and Contributions
Her final TV credit came in 2021 as the narration of Alpha Control in an episode of a digital platform’s remake of Lost in Space. In the big screen version featuring 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 later 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 later feature films was the fantasy, Troll (1986) in which she portrayed a witch, 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 doctor. In addition to Anne, they had another daughter, June. That union ended in separation, as did her second marriage, to John Lindsay, an architect.
She is survived by her daughters and four grandkids.
