Starting her career in films, June Lockhart, who died aged 100, achieved her biggest success after shifting largely to television. Having been offered few opportunities to shine in movies from her debut as a child in 1938 until 1947, she thrived on TV in numerous beloved series, most notably in Lassie.
Becoming Ruth Martin on Lassie
Taking over from another actress in 1958, Lockhart remained in the show until 1964. Her role was Ruth Martin, wed to agriculturalist Paul Martin and the foster mother of young Timmy Martin, whose dog was the titular hero of the series.
In her role as a housewife, Lockhart somehow succeeded to avoid being completely upstaged by the intelligent canine. She described the show as “a fantasy about families on a rural property in which the canine solves all the issues in 22 minutes, in time for the last commercial”. After she departed the series, Lockhart commented: “In six sexless years of playing a rural spouse and parent, I was hardly ever permitted to peck my on-screen husband on the cheek.”
Featuring in Lost in Space
Lockhart went directly into another hit, Lost in Space (1965-68), a partly comedic sci-fi series aimed primarily at young audiences and based by The Swiss Family Robinson. Lockhart and her co-star portrayed Maureen and John Robinson, two scientists exploring alien planets. Lockhart had to spend the majority of her time deftly trying to navigate special effects. As the show continued, the storyline became less and less about this space family and increasingly about the young son and his friendship with a robot, and the cowardly villain Dr Zachary Smith.
Beginnings in Entertainment
Lockhart’s movie first role, 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 actual parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canada-native Gene were both performers in dozens of films, as well as on stage, it was nearly certain that June, who was born in New York, would enter 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).
Move to Hollywood and Film Roles
When her father was offered a contract by a film studio, after his success on Broadway, she moved with her parents to Hollywood, where Gene made approximately 300 films. After going to school in Beverly Hills, June began her professional life 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 latter, she is delightful as a New Yorker at a household party, whose dance card is filled spitefully to prevent Lockhart interacting with her brother.
More importantly, although she did not realize it at the time, was Son of Lassie (1945). It was one of several sequels to the hugely successful Lassie Come Home (1943), in which another actress had played the female character who assists the canine to escape 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 offspring, Laddie, protagonist of a wartime story in Nazi-occupied Norway, was in the minds of the producers when it came to casting the Lassie TV series 13 years later.
TV and Stage Work
Although she was offered 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 solution. Before embarking in a new direction, she received acclaim on Broadway in For Love or Money (1947), a comedy for which she won a Tony award as best newcomer.
A further significant run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a doctor and maternal character. She also appeared regularly in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy schedule continued for the following five decades, with a regular 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 presenter finds a stray collie, and in another sitcom in 1995 as the mother of a restaurant manager.
Final Roles and Achievements
Her last TV appearance 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 starring well-known actors (1998), she had a digital 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 attended the organization’s launches and other events. In 2013 her work as a volunteer spokesperson 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 married John Maloney, a physician and former Navy doctor. In addition to Anne, they had a second daughter, June. That marriage ended in divorce, as did her second marriage, to John Lindsay, an designer.
She is remembered by her daughters and four grandchildren.
