June Lockhart, who died at the remarkable age of 100, started her career in films, but achieved recognition after transitioning almost entirely to TV. Having been offered few chances to shine in films from her debut as a child in 1938 until 1947, she thrived on TV in many popular series, most notably in Lassie.
Portraying Ruth Martin on Lassie
Taking over from another actress in 1958, Lockhart continued in the show until 1964. She played Ruth Martin, wed to agriculturalist Paul Martin and the foster mother of young Timmy Martin, whose collie was the titular star of the series.
In her role as a housewife, Lockhart somehow managed to avoid being completely upstaged by the intelligent canine. She described the show as “a fairy tale about families on a rural property in which the dog resolves all the problems in 22 minutes, in time for the last commercial”. After she left the series, Lockhart commented: “In six sexless years of playing a rural spouse and mother, I was hardly ever allowed to kiss my co-star on the face.”
Starring in Lost in Space
Lockhart went straight into a second successful series, Lost in Space (1965-68), a partly comedic science fiction series targeted mostly at children and inspired by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two scientists exploring alien planets. Lockhart had to spend most of her time deftly trying to navigate special effects. As the show progressed, the storyline became increasingly less about this interstellar family and increasingly about the boy and his bond with a robot, and the cowardly antagonist Dr Zachary Smith.
Early Career and Family Background
Lockhart’s movie debut, at the young 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 British-born Kathleen and Canadian-born Gene were both actors in many of movies, as well as on theater, it was almost inevitable that June, who was born in New York, would enter show business.
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).
Hollywood Work
When her parent was offered a contract by a film studio, after his acclaim on Broadway, she moved with her parents to Hollywood, where Gene made approximately 300 films. After attending school in Beverly Hills, June began her professional life 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 last one, she is delightful as a New Yorker at a household party, whose schedule is arranged spitefully 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 follow-ups to the extremely successful Lassie Come Home (1943), in which another actress had played the female character who assists the canine to escape to the owners. In the later film, Lockhart played the now adult version.
The affectionate way in which she interacted with both Lassie and her son, Laddie, hero of a World War II adventure in Nazi-occupied Norway, was in the consideration of the creators when it came to selecting the Lassie TV series 13 years later.
Shift to Television and Broadway Success
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 getting her nowhere and that TV would be the answer. Before embarking 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 most promising newcomer.
A additional 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 cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy schedule continued for the following five decades, with a regular role in General Hospital between 1984 and 1998. Among her many guest appearances were as herself in a 1988 episode of a comedy series, where the presenter finds a lost collie, and in another sitcom in 1995 as the parent of a restaurant manager.
Final Roles and Achievements
Her final TV credit came in 2021 as the voice of Alpha Control in an episode of a streaming service’s remake of Lost in Space. In the movie version featuring famous actors (1998), she had a holographic cameo as a school principal. She took pleasure in learning how much of an influence the first series had been to later astronauts, and often attended the agency’s launches and other events. In 2013 her work as a volunteer spokesperson brought her its prestigious award.
Among her few later feature films was the fantasy, Troll (1986) in which she played a witch, with her own daughter, Anne Lockhart, playing her younger self.
Private Details
In 1951 she wed John Maloney, a physician and former Navy medical officer. In addition to Anne, they had another daughter, June. That marriage ended in separation, as did her second marriage, to John Lindsay, an designer.
She is remembered by her daughters and four grandchildren.
