Starting her career in cinema, June Lockhart, who died aged 100, found her greatest success after switching predominantly to television. Having been given few opportunities to excel in films from her debut as a youngster in 1938 until 1947, she excelled on television in numerous popular series, especially in Lassie.
Portraying Ruth Martin on Lassie
Stepping in 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 dog was the eponymous hero of the series.
Despite playing a mother figure, Lockhart skillfully avoided being outshone by the brilliant dog. She characterized the program as “a fairy tale about people on a rural property in which the dog solves all the problems in 22 minutes, in time for the last advertisement”. After she left the show, Lockhart commented: “In six sexless years of playing a country spouse and mother, I was hardly ever allowed to peck my on-screen husband on the face.”
Journey into Lost in Space
Lockhart went straight into a second hit, Lost in Space (1965-68), a semi-spoof science fiction series aimed primarily at children and based by The Swiss Family Robinson. Lockhart and another actor portrayed Maureen and John Robinson, two scientists exploring alien planets. Lockhart had to spend the majority of her time deftly trying to navigate visual effects. As the show continued, the narrative became increasingly less about this interstellar clan and increasingly about the young son and his bond with a robot, and the cowardly antagonist Dr Zachary Smith.
Initial Career and Family Influence
Lockhart’s feature film first role, at the young 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 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 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 opera at the Metropolitan Opera in New York (1931).
Hollywood Career
When her father was given a deal by a film studio, after his success 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 films, 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 charming as a New Yorker at a family party, whose schedule is filled maliciously to stop Lockhart dancing with her sibling.
More importantly, 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 female character who assists the canine to return to the family. In the later film, Lockhart played the now adult character.
The affectionate way in which she handled both Lassie and her son, Laddie, protagonist of a wartime adventure in enemy-held Norway, was in the minds of the producers when it came to selecting the Lassie TV series 13 years later.
TV and Stage Work
Although she was offered major roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her film career was stagnating and that TV would be the solution. Before embarking in a different direction, she won acclaim on Broadway in For Love or Money (1947), a comedy for which she won a Tony award as most promising newcomer.
A further significant run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a physician and mother figure. She also featured frequently in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic schedule continued for the next 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 dining manager.
Later Roles and Contributions
Her last TV credit came in 2021 as the narration of Alpha Control in an episode of a digital platform’s remake of Lost in Space. In the movie version starring well-known actors (1998), she had a digital cameo as a school principal. She took joy in learning how much of an inspiration the original series had been to later astronauts, and often participated in the agency’s launches and other events. In 2013 her work as a unpaid spokesperson brought her its prestigious award.
Among her few subsequent feature films was the fantasy, Troll (1986) in which she played a witch, with her own daughter, Anne Lockhart, playing her younger self.
Personal Life and Family
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 divorce, as did her subsequent marriage, to John Lindsay, an designer.
She is survived by her daughters and four grandchildren.
