June Lockhart, who died at the remarkable age of 100, started her career in films, but gained recognition after transitioning almost exclusively to television. Having been offered limited chances to shine in films from her debut as a youngster in 1938 until 1947, she thrived on TV in numerous popular series, especially in Lassie.
Becoming Ruth Martin on Lassie
Taking over from another actress in 1958, Lockhart remained in the series until 1964. Her role was Ruth Martin, married to farmer Paul Martin and the adoptive mother of young Timmy Martin, whose dog was the titular hero of the series.
In her part as a housewife, Lockhart somehow succeeded to avoid being totally overshadowed by the clever dog. She characterized the program as “a fantasy about people on a rural property in which the dog solves all the problems in 22 minutes, in time for the last commercial”. After she departed the series, Lockhart remarked: “In six sexless years of playing a rural wife and parent, I was rarely allowed to peck my co-star on the face.”
Starring in Lost in Space
Lockhart went directly into a second hit, Lost in Space (1965-68), a partly comedic science fiction 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 distant planets. Lockhart had to spend the majority of her time skillfully trying to survive special effects. As the show continued, the storyline became increasingly less about this space family and increasingly about the young son and his friendship with a mechanical being, and the cowardly villain Dr Zachary Smith.
Start in Show Business
Lockhart’s movie debut, at the 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 British-born Kathleen and Canadian-born Gene were both actors in many 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 appearance, at the tender age of six, came in a non-singing role in an opera at the Metropolitan Opera in New York (1931).
Hollywood Career
When her parent was offered a deal by a film studio, after his success on Broadway, she moved with her family to Hollywood, where Gene made approximately 300 films. After attending school in Beverly Hills, June began her career in films, mostly in minor roles in prestigious pictures such as Sergeant York (1941), The White Cliffs of Dover (1942) and Meet Me in St Louis (1944). In the latter, she is delightful as a New Yorker at a family party, whose dance card is filled spitefully to prevent Lockhart dancing with her sibling.
More significantly, although she did not realize 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 another actress had played the female character who assists the dog to return to the owners. In the subsequent film, Lockhart played the now grown-up version.
The affectionate way in which she handled both Lassie and her son, Laddie, hero of a wartime story 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 offered major roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her film career was getting her nowhere and that TV would be the solution. Before embarking in a new direction, she received praise on Broadway in For Love or Money (1947), a humorous play for which she won a Tony award as most promising newcomer.
A further substantial run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a physician 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 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 stray collie, and in another sitcom in 1995 as the mother of a dining manager.
Final Roles and Achievements
Her final TV credit 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 featuring famous actors (1998), she had a digital cameo as a school principal. She took pleasure in learning how much of an inspiration the first series had been to later astronauts, and often attended the organization’s launches and other events. In 2013 her work as a unpaid spokesperson brought her its Exceptional Public Achievement Medal.
Among her limited later feature films was the fantasy, Troll (1986) in which she played a sorceress, with her own daughter, Anne Lockhart, playing her younger self.
Private Details
In 1951 she married 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 remembered by her children and four grandkids.
