Launching her career in films, June Lockhart, who passed on aged 100, found her greatest success after shifting largely to television. Having been given limited chances to excel in movies from her debut as a youngster in 1938 until 1947, she thrived on television in many beloved series, most notably in Lassie.
Portraying Ruth Martin on Lassie
Stepping in from a previous star in 1958, Lockhart remained in the show until 1964. Her role was Ruth Martin, wed to farmer Paul Martin and the foster mother of young Timmy Martin, whose collie was the eponymous hero of the series.
Despite playing a housewife, Lockhart skillfully avoided being outshone by the brilliant animal star. She described the program as “a fairy tale about families on a rural property in which the canine solves all the problems in 22 minutes, in time for the last commercial”. After she departed the series, Lockhart remarked: “In six chaste years of playing a rural wife and parent, I was rarely permitted to kiss my co-star on the face.”
Featuring in Lost in Space
Lockhart went straight into another hit, Lost in Space (1965-68), a partly comedic sci-fi series aimed primarily at children and inspired by The Swiss Family Robinson. Lockhart and her co-star played 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 continued, the storyline became less and less about this interstellar family and increasingly about the young son and his bond with a robot, and the timid villain Dr Zachary Smith.
Beginnings in Entertainment
Lockhart’s movie 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 real-life parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canadian-born Gene were both actors in dozens of films, as well as on theater, it was almost inevitable that June, who was born in New York, would join the entertainment industry.
Her first theatrical performance, at the 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 Movie Roles
When her father was given a contract by a film studio, after his success on Broadway, she moved with her parents to Hollywood, where Gene made around 300 films. After going to school in Beverly Hills, June started her career in films, mostly 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 last one, she is charming as a New Yorker at a family party, whose schedule is filled maliciously to stop Lockhart dancing 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 hugely successful Lassie Come Home (1943), in which another actress had played the female character who assists the canine to return to the owners. In the later film, Lockhart played the now grown-up version.
The loving way in which she interacted with both Lassie and her son, Laddie, protagonist of a World War II story in Nazi-occupied Norway, was in the minds of the creators when it came to selecting the Lassie TV series 13 years later.
Television and Stage Career
Although she was offered major roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her movie career was getting her nowhere and that television would be the solution. Before going in a new direction, she won acclaim 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 cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic workload persisted 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.
Later Roles and Achievements
Her final TV credit came in 2021 as the voice of Alpha Control in an episode of a streaming service’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 original series had been to later astronauts, and often attended the agency’s launches and other events. In 2013 her work as a unpaid spokesperson brought her its prestigious award.
Among her few later feature films was the fantasy, Troll (1986) in which she played a witch, with her own daughter, Anne Lockhart, playing her earlier self.
Personal Details
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 divorce, as did her subsequent marriage, to John Lindsay, an designer.
She is remembered by her daughters and four grandchildren.
