June Lockhart, who passed away at the age of 100, started her career in films, but gained fame after transitioning almost exclusively to TV. Having been offered limited opportunities to excel in movies from her first appearance as a child in 1938 until 1947, she excelled on television in numerous beloved series, most notably in Lassie.
Her Memorable Role in Lassie
Stepping in from a previous star in 1958, Lockhart continued in the series until 1964. Her role was Ruth Martin, married 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 role as a housewife, Lockhart somehow succeeded to avoid being completely overshadowed by the clever canine. She described the show as “a fairy tale about families on a rural property in which the canine resolves all the issues in 22 minutes, in time for the last advertisement”. After she left the series, Lockhart remarked: “In six chaste years of playing a country wife and parent, I was hardly ever allowed to peck my co-star on the cheek.”
Featuring in Lost in Space
Lockhart went directly into a second hit, Lost in Space (1965-68), a partly comedic science fiction series targeted mostly at young audiences 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 the majority of her time skillfully trying to survive visual effects. As the show progressed, the storyline became increasingly less about this interstellar clan and more about the young son and his bond with a mechanical being, and the timid antagonist Dr Zachary Smith.
Initial Career and Family Background
Lockhart’s movie first role, at the age of 13, had come as Belinda Cratchit in A Christmas Carol (1938). In the roles of her mother and father, Bob and Mrs Cratchit, were her real-life parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canada-native Gene were both actors in many of movies, as well as on stage, it was almost inevitable that June, who was born in New York, would join show business.
Her first theatrical performance, at the tender age of six, came in a non-musical role in an opera at the Metropolitan Opera in New York (1931).
Transition to Hollywood and Movie Roles
When her father was offered a deal 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 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 household party, whose schedule is filled spitefully 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 girl who assists the dog to escape to the family. 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 adventure in Nazi-occupied Norway, was in the minds of the creators 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 movie career was getting her nowhere and that television would be the solution. Before embarking 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 most promising newcomer.
A additional substantial run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a doctor 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 hectic schedule persisted for the next five decades, with a regular 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 dining manager.
Later Roles and Achievements
Her last 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 starring 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 organization’s launches and other events. In 2013 her work as a unpaid representative brought her its Exceptional Public Achievement Medal.
Among her limited subsequent feature films was the fantasy, Troll (1986) in which she played a sorceress, with her own daughter, Anne Lockhart, playing her younger self.
Private Information
In 1951 she married John Maloney, a doctor and former Navy medical officer. In addition to Anne, they had a second daughter, June. That marriage ended in separation, as did her subsequent marriage, to John Lindsay, an architect.
She is remembered by her daughters and four grandchildren.
