June Lockhart, who passed away at the remarkable age of 100, started her career in movies, but gained fame after transitioning almost entirely to television. Having been given few opportunities to shine in films from her first appearance as a child in 1938 until 1947, she excelled on TV in numerous popular series, especially in Lassie.
Becoming Ruth Martin on Lassie
Stepping in from a previous star in 1958, Lockhart remained in the series until 1964. Her role was Ruth Martin, wed to farmer Paul Martin and the foster mother of young Timmy Martin, whose dog was the titular star of the series.
Even with playing a housewife, Lockhart skillfully avoided being outshone by the smart animal star. She characterized the show as “a fantasy about people on a farm in which the dog resolves all the issues in 22 minutes, in time for the last commercial”. After she left the series, Lockhart commented: “In six chaste years of playing a rural spouse and mother, I was rarely allowed to peck my on-screen husband on the cheek.”
Featuring in Lost in Space
Lockhart went directly into another successful series, Lost in Space (1965-68), a semi-spoof sci-fi series targeted primarily at young audiences and inspired by The Swiss Family Robinson. Lockhart and another actor portrayed Maureen and John Robinson, two scientists exploring distant planets. Lockhart had to spend the majority of her time deftly trying to survive visual effects. As the show continued, the narrative became less and less about this space family and increasingly about the boy and his friendship with a mechanical being, and the cowardly villain Dr Zachary Smith.
Early Career and Family Influence
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 UK-native Kathleen and Canada-native Gene were both performers in many of movies, as well as on stage, it was nearly 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).
Transition to Hollywood and Movie Roles
When her father was offered a contract by a motion picture studio, after his success on Broadway, she moved with her family to Hollywood, where Gene made around 300 films. After going to school in Beverly Hills, June began her professional life in movies, 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 charming as a New Yorker at a household party, whose schedule is filled maliciously to prevent 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 several follow-ups to the hugely successful Lassie Come Home (1943), in which another actress had played the girl who helps the dog to return to the owners. In the subsequent film, Lockhart played the now adult version.
The affectionate way in which she interacted with both Lassie and her offspring, Laddie, protagonist of a World War II story in enemy-held Norway, was in the minds of the producers when it came to casting the Lassie TV series 13 years later.
Transition to Television and Stage 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 stagnating and that television would be the solution. Before embarking 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 most promising newcomer.
A additional substantial run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a physician and mother figure. She also appeared regularly in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy schedule persisted for the next five decades, with a recurring role in General Hospital between 1984 and 1998. Among her many guest appearances were as the actress in a 1988 episode of a talkshow, where the presenter finds a stray collie, and in another sitcom in 1995 as the parent of a restaurant manager.
Final Career and Legacy
Her final TV credit 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 pleasure in learning how much of an inspiration the original series had been to later astronauts, and often participated in the agency’s launches and other events. In 2013 her work as a volunteer spokesperson brought her its prestigious award.
Among her limited later feature films was the fantasy, Troll (1986) in which she played a sorceress, with her own daughter, Anne Lockhart, playing her younger self.
Personal Details
In 1951 she married John Maloney, a doctor and former Navy doctor. In addition to Anne, they had a second daughter, June. That union ended in separation, as did her subsequent marriage, to John Lindsay, an designer.
She is remembered by her children and four grandchildren.
