Starting her career in cinema, June Lockhart, who died aged 100, achieved her biggest success after switching predominantly to television. Having been offered few chances to shine in films from her debut as a youngster in 1938 until 1947, she thrived on TV in many popular series, most notably in Lassie.
Her Iconic Role in Lassie
Stepping in from another actress in 1958, Lockhart continued in the series until 1964. She played Ruth Martin, wed to agriculturalist Paul Martin and the foster mother of young Timmy Martin, whose collie was the titular hero of the series.
Despite playing a housewife, Lockhart adeptly avoided being overshadowed by the smart animal star. She characterized the program as “a fairy tale about people on a rural property in which the canine solves all the issues in 22 minutes, in time for the last commercial”. After she left the show, Lockhart commented: “In six sexless years of playing a country spouse and parent, I was hardly ever allowed to peck my on-screen husband on the face.”
Adventure into Lost in Space
Lockhart went straight into a second successful series, Lost in Space (1965-68), a partly comedic sci-fi series targeted mostly at young audiences and inspired by The Swiss Family Robinson. Lockhart and another actor portrayed Maureen and John Robinson, two scientists investigating distant planets. Lockhart had to spend the majority of her time deftly trying to navigate visual effects. As the series continued, the storyline became increasingly less about this interstellar clan and more about the young son and his friendship with a mechanical being, and the timid antagonist Dr Zachary Smith.
Initial Career and Family Influence
Lockhart’s feature film debut, 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 actual 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 nearly inevitable that June, who was born in New York, would enter the entertainment industry.
Her first theatrical performance, at the 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 parent 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 movies, mainly in minor 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 family party, whose dance card is arranged maliciously to prevent Lockhart dancing with her sibling.
More significantly, although she did not know 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 a young star had played the female character who assists the canine to return to the owners. 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 World War II adventure in Nazi-occupied Norway, was in the consideration of the creators when it came to casting the Lassie TV series 13 years later.
Shift to Television and Stage Success
Although she was given 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 answer. Before embarking in a different direction, she received acclaim on Broadway in For Love or Money (1947), a humorous play for which she won a Tony award as most promising 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 featured regularly in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic schedule continued for the next 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 parent of a restaurant manager.
Final Career and Impact
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 influence the original 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 few subsequent feature films was the fantasy, Troll (1986) in which she portrayed a sorceress, with her own daughter, Anne Lockhart, playing her earlier 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 marriage ended in divorce, as did her second marriage, to John Lindsay, an architect.
She is remembered by her children and four grandkids.
