June Lockhart, who died at the remarkable age of 100, began her career in films, but gained recognition after moving almost exclusively to television. Having been offered limited opportunities to shine in films from her debut as a youngster in 1938 until 1947, she excelled on TV in numerous popular series, especially in Lassie.
Becoming Ruth Martin on Lassie
Stepping in from another actress in 1958, Lockhart remained in the series until 1964. She played Ruth Martin, wed to agriculturalist Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose dog was the titular hero of the series.
Despite playing a housewife, Lockhart adeptly avoided being overshadowed by the brilliant animal star. She described the show as “a fairy tale about families on a rural property in which the canine solves all the problems in 22 minutes, in time for the last commercial”. After she left the show, Lockhart commented: “In six chaste years of playing a rural spouse and parent, 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 semi-spoof sci-fi series aimed primarily at children and based by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two researchers investigating alien planets. Lockhart had to spend most of her time deftly trying to survive visual effects. As the series continued, the narrative became increasingly less about this interstellar family and more about the young son and his bond with a mechanical being, and the cowardly antagonist Dr Zachary Smith.
Beginnings in Entertainment
Lockhart’s feature film first role, at the age of 13, had come as Belinda Cratchit in A Christmas Carol (1938). In the parts of her parents, Bob and Mrs Cratchit, were her actual parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canadian-born Gene were both performers in dozens of movies, as well as on stage, it was almost certain that June, who was born in New York, would join show business.
Her first theatrical performance, at the tender age of six, came in a non-singing role in an musical production at the Metropolitan Opera in New York (1931).
Transition to Hollywood and Movie Roles
When her parent was offered a deal by a motion picture studio, after his success on Broadway, she relocated with her family to Hollywood, where Gene made around 300 films. After attending school in Beverly Hills, June started her professional life in films, mostly 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 charming as a New Yorker at a household party, whose dance card is filled spitefully to stop Lockhart interacting with her sibling.
More importantly, although she did not realize it at the time, was Son of Lassie (1945). It was one of multiple sequels to the hugely successful Lassie Come Home (1943), in which a young star had played the female character who assists the dog to return to the owners. In the later film, Lockhart played the now grown-up version.
The affectionate way in which she interacted with both Lassie and her son, Laddie, hero of a wartime adventure in enemy-held Norway, was in the minds of the creators when it came to casting the Lassie TV series 13 years later.
Transition to Television and Broadway Success
Although she was given major roles in two thrillers, 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 new direction, she won praise 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 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 herself in a 1988 episode of a talkshow, where the host finds a lost collie, and in another sitcom in 1995 as the parent of a dining manager.
Final Career and Legacy
Her last TV appearance came in 2021 as the narration of Alpha Control in an episode of a digital platform’s new version of Lost in Space. In the movie 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 future astronauts, and often participated in the agency’s launches and other events. In 2013 her work as a volunteer representative brought her its Exceptional Public Achievement Medal.
Among her few later feature films was the fantasy, Troll (1986) in which she played a sorceress, with her own daughter, Anne Lockhart, playing her earlier self.
Private Information
In 1951 she married John Maloney, a physician and former Navy doctor. In addition to Anne, they had a second daughter, June. That union ended in separation, as did her second marriage, to John Lindsay, an designer.
She is remembered by her children and four grandkids.
