Starting her career in cinema, June Lockhart, who died aged 100, achieved her greatest success after switching predominantly to television. Having been offered few chances to excel in films from her debut as a child in 1938 until 1947, she thrived on TV in many popular series, most notably in Lassie.
Her Iconic Role in Lassie
Stepping in from a previous star in 1958, Lockhart remained in the show until 1964. Her role was Ruth Martin, wed to farmer Paul Martin and the adoptive mother of young Timmy Martin, whose dog was the eponymous hero of the series.
In her part as a housewife, Lockhart somehow succeeded to avoid being completely overshadowed by the intelligent dog. She described the program as “a fantasy about people on a rural property in which the dog resolves 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 country spouse and parent, I was rarely allowed to kiss my co-star on the face.”
Adventure into Lost in Space
Lockhart went straight into another successful series, Lost in Space (1965-68), a semi-spoof sci-fi series targeted primarily at children and inspired by The Swiss Family Robinson. Lockhart and another actor portrayed Maureen and John Robinson, two researchers investigating distant planets. Lockhart had to spend the majority of her time deftly trying to survive special effects. As the series continued, the storyline became less and less about this space family and more about the young son and his friendship with a mechanical being, and the cowardly antagonist Dr Zachary Smith.
Beginnings 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 parts of her mother and father, Bob and Mrs Cratchit, were her real-life parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canadian-born Gene were both performers in many of films, as well as on theater, it was almost inevitable that June, who was born in New York, would enter show business.
Her first theatrical appearance, at the age of six, came in a non-singing role in an musical production at the Metropolitan Opera in New York (1931).
Hollywood Career
When her parent was offered a deal by a motion picture studio, after his acclaim on Broadway, she relocated with her family to Hollywood, where Gene made approximately 300 films. After attending school in Beverly Hills, June began her professional life in movies, 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 charming as a New Yorker at a household party, whose dance card is arranged maliciously to prevent Lockhart dancing with her sibling.
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 a young star had played the girl who assists 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 adventure in Nazi-occupied Norway, was in the consideration of the producers when it came to selecting the Lassie TV series 13 years later.
TV and Stage Career
Although she was given major roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her movie 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 humorous play for which she won a Tony award as best newcomer.
A further substantial run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a doctor and mother figure. She also appeared frequently in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic workload persisted for the following five decades, with a recurring role in General Hospital between 1984 and 1998. Among her many one-off appearances were as the actress in a 1988 episode of a talkshow, where the presenter finds a lost collie, and in another sitcom in 1995 as the parent of a dining manager.
Later Career and Impact
Her final TV credit came in 2021 as the narration of Alpha Control in an episode of a streaming service’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 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 volunteer representative brought her its prestigious award.
Among her limited later feature films was the fantasy, Troll (1986) in which she played a witch, with her own daughter, Anne Lockhart, playing her earlier self.
Private 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 separation, as did her subsequent marriage, to John Lindsay, an designer.
She is survived by her daughters and four grandkids.
