June Lockhart, who died at the remarkable age of 100, began her professional journey in films, but gained fame after transitioning almost entirely to television. Having been offered few opportunities to excel in movies from her first appearance as a child in 1938 until 1947, she thrived on television in many beloved series, most notably in Lassie.
Her Iconic Role in Lassie
Taking over from a previous star in 1958, Lockhart continued in the show until 1964. Her role was Ruth Martin, wed to agriculturalist Paul Martin and the foster mother of seven-year-old Timmy Martin, whose dog was the titular hero of the series.
In her part as a housewife, Lockhart somehow managed to avoid being completely upstaged by the intelligent canine. She described the program as “a fairy tale about people on a farm in which the canine resolves all the problems in 22 minutes, in time for the last advertisement”. After she departed the show, Lockhart remarked: “In six sexless years of playing a rural spouse and parent, I was hardly ever allowed to peck my co-star on the face.”
Adventure into Lost in Space
Lockhart went directly into a second successful series, Lost in Space (1965-68), a semi-spoof science fiction series aimed mostly at young audiences and inspired by The Swiss Family Robinson. Lockhart and another actor portrayed Maureen and John Robinson, two researchers exploring alien planets. Lockhart had to spend the majority of her time skillfully trying to survive special effects. As the show progressed, the storyline became less and less about this space clan and more about the boy and his friendship with a mechanical being, and the timid antagonist Dr Zachary Smith.
Initial Career and Family Background
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 British-born Kathleen and Canadian-born Gene were both actors in dozens of films, as well as on stage, it was almost certain that June, who was born in New York, would enter show business.
Her first stage performance, at the tender age of six, came in a non-musical role in an opera at the Metropolitan Opera in New York (1931).
Cinema Work
When her father was offered a contract by a motion picture studio, after his success on Broadway, she relocated with her parents to Hollywood, where Gene made approximately 300 films. After attending school in Beverly Hills, June started her professional life in films, mostly 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 last one, she is delightful as a New Yorker at a household party, whose dance card is filled maliciously to stop Lockhart interacting with her brother.
More significantly, although she did not know it at the time, was Son of Lassie (1945). It was one of several sequels to the extremely successful Lassie Come Home (1943), in which a young star had played the female character who helps the dog to escape to the owners. In the later film, Lockhart played the now grown-up version.
The loving way in which she handled both Lassie and her son, Laddie, protagonist of a World War II story in Nazi-occupied Norway, was in the minds of the producers when it came to casting the Lassie TV series 13 years later.
Television and Stage Career
Although she was given leading roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her film career was stagnating 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 comedy for which she won a Tony award as most promising newcomer.
A additional significant run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a doctor and maternal character. She also featured regularly in TV cowboy shows 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 regular role in General Hospital between 1984 and 1998. Among her many one-off appearances were as herself 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.
Later Career and Legacy
Her final TV appearance came in 2021 as the voice of Alpha Control in an episode of a streaming service’s new version of Lost in Space. In the big screen 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 first series had been to future astronauts, and often participated in the agency’s launches and other events. In 2013 her work as a volunteer representative brought her its prestigious award.
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 earlier self.
Personal Details
In 1951 she wed John Maloney, a physician and former Navy medical officer. In addition to Anne, they had a second daughter, June. That marriage ended in divorce, as did her subsequent marriage, to John Lindsay, an architect.
She is survived by her daughters and four grandkids.
