Launching her career in films, June Lockhart, who died aged 100, found her biggest success after switching largely to the small screen. Having been offered few opportunities to shine in films from her first appearance as a youngster in 1938 until 1947, she excelled on TV in numerous beloved series, especially in Lassie.
Her Memorable Role in Lassie
Stepping in from a previous star in 1958, Lockhart remained in the series until 1964. She played Ruth Martin, married to agriculturalist Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose collie was the eponymous star of the series.
In her role as a homemaker, Lockhart somehow managed to avoid being completely overshadowed by the clever canine. She described the program as “a fairy tale about families on a rural property in which the dog solves all the issues in 22 minutes, in time for the last commercial”. After she departed the show, Lockhart commented: “In six chaste years of playing a country spouse and mother, I was hardly ever allowed to peck my co-star on the face.”
Journey into Lost in Space
Lockhart went directly into a second hit, Lost in Space (1965-68), a partly comedic sci-fi series aimed mostly at young audiences and inspired by The Swiss Family Robinson. Lockhart and her co-star played Maureen and John Robinson, two scientists investigating alien planets. Lockhart had to spend the majority of her time skillfully trying to navigate visual effects. As the series continued, the narrative became increasingly less about this space family and increasingly about the young son and his bond with a robot, and the timid antagonist Dr Zachary Smith.
Start 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 UK-native Kathleen and Canadian-born Gene were both actors in dozens of movies, 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 tender age of six, came in a non-singing role in an opera at the Metropolitan Opera in New York (1931).
Cinema Work
When her father was given a contract by a film studio, after his success on Broadway, she moved with her family to Hollywood, where Gene made around 300 films. After attending school in Beverly Hills, June began her career in movies, mainly in small 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 delightful as a New Yorker at a household party, whose dance card is arranged spitefully to stop Lockhart interacting with her sibling.
More importantly, although she did not realize 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 canine to return to the family. In the subsequent film, Lockhart played the now grown-up version.
The loving way in which she handled both Lassie and her offspring, Laddie, protagonist of a wartime story in enemy-held Norway, was in the minds of the producers when it came to selecting the Lassie TV series 13 years later.
Television and Stage Work
Although she was given major 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 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 best newcomer.
A additional significant run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a doctor 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 continued for the next five decades, with a regular role in General Hospital between 1984 and 1998. Among her many one-off appearances were as the actress in a 1988 episode of a comedy series, where the host finds a lost collie, and in another sitcom in 1995 as the mother of a dining manager.
Later Roles and Achievements
Her final TV appearance came in 2021 as the narration 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 digital cameo as a school principal. She took joy in learning how much of an inspiration the first series had been to later astronauts, and often attended the organization’s launches and other events. In 2013 her work as a unpaid spokesperson brought her its Exceptional Public Achievement Medal.
Among her limited subsequent feature films was the fantasy, Troll (1986) in which she portrayed a witch, with her own daughter, Anne Lockhart, playing her younger self.
Personal Information
In 1951 she wed John Maloney, a doctor and former Navy doctor. In addition to Anne, they had a second daughter, June. That union ended in divorce, as did her second marriage, to John Lindsay, an designer.
She is remembered by her children and four grandkids.
