Starting her career in films, June Lockhart, who died aged 100, found her biggest success after shifting largely to the small screen. Having been given limited chances to shine in movies from her debut as a child in 1938 until 1947, she thrived on television in numerous beloved series, especially in Lassie.
Her Memorable Role in Lassie
Taking over from a previous star in 1958, Lockhart remained in the series until 1964. She played Ruth Martin, wed to farmer Paul Martin and the adoptive mother of young Timmy Martin, whose collie was the eponymous star of the series.
In her role as a housewife, Lockhart somehow managed to avoid being totally upstaged by the intelligent canine. She described the show as “a fantasy about people on a rural property in which the canine resolves all the issues in 22 minutes, in time for the last advertisement”. After she departed the show, Lockhart commented: “In six sexless years of playing a rural wife and mother, I was hardly ever permitted to peck my on-screen husband on the cheek.”
Adventure into Lost in Space
Lockhart went directly 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 played Maureen and John Robinson, two scientists investigating alien planets. Lockhart had to spend the majority of her time skillfully trying to navigate special effects. As the series continued, the storyline became increasingly less about this space 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 Influence
Lockhart’s movie debut, 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 Canada-native Gene were both actors in dozens of movies, as well as on stage, it was nearly certain that June, who was born in New York, would join show business.
Her first stage appearance, at the age of six, came in a non-musical role in an opera at the Metropolitan Opera in New York (1931).
Move to Hollywood and Movie Roles
When her parent was given a contract by a motion picture studio, after his success on Broadway, she moved with her family to Hollywood, where Gene made approximately 300 films. After going to school in Beverly Hills, June began her career in films, mainly 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 last one, she is delightful as a New Yorker at a household party, whose schedule is arranged maliciously to prevent Lockhart dancing with her brother.
More significantly, although she did not know it at the time, was Son of Lassie (1945). It was one of several follow-ups to the extremely successful Lassie Come Home (1943), in which another actress had played the girl who assists the canine to return to the family. In the later film, Lockhart played the now grown-up character.
The affectionate way in which she handled both Lassie and her son, Laddie, hero of a World War II story in enemy-held Norway, was in the minds of the producers when it came to selecting the Lassie TV series 13 years later.
Shift to Television and Broadway Success
Although she was offered 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 TV would be the solution. 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 rural hotel, where Lockhart is a physician 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 busy workload persisted for the next five decades, with a recurring 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 host finds a stray collie, and in another sitcom in 1995 as the mother of a restaurant manager.
Later Roles and Achievements
Her final 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 featuring famous 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 attended the agency’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 wed John Maloney, a physician and former Navy doctor. In addition to Anne, they had another daughter, June. That union ended in divorce, as did her subsequent marriage, to John Lindsay, an architect.
She is remembered by her daughters and four grandchildren.
