Launching her career in films, June Lockhart, who passed on aged 100, found her biggest success after shifting largely to television. Having been given limited chances to excel in films from her first appearance as a youngster in 1938 until 1947, she excelled on television in many popular series, most notably in Lassie.
Portraying Ruth Martin on Lassie
Stepping in from a previous star in 1958, Lockhart continued in the show until 1964. She played Ruth Martin, wed to farmer Paul Martin and the foster mother of seven-year-old Timmy Martin, whose collie was the eponymous star of the series.
In her part as a homemaker, Lockhart somehow managed to avoid being completely overshadowed by the intelligent canine. She characterized the program as “a fairy tale about families on a rural property in which the dog solves all the issues 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 peck my on-screen husband on the face.”
Starring in Lost in Space
Lockhart went directly into another successful series, Lost in Space (1965-68), a semi-spoof science fiction series aimed primarily at young audiences and based by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two scientists exploring distant planets. Lockhart had to spend most of her time skillfully trying to survive visual effects. As the show continued, the storyline became increasingly less about this space clan and more about the boy and his friendship with a mechanical being, and the cowardly villain Dr Zachary Smith.
Beginnings in Show Business
Lockhart’s movie 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 actual parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canadian-born Gene were both actors in many of films, as well as on theater, it was almost certain that June, who was born in New York, would enter show business.
Her first stage appearance, at the tender age of six, came in a non-musical role in an opera at the Metropolitan Opera in New York (1931).
Hollywood Career
When her parent was offered a deal by a motion picture studio, after his acclaim 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 professional life 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 charming as a New Yorker at a family party, whose schedule is filled maliciously to prevent Lockhart interacting with her sibling.
More importantly, although she did not know 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 girl who helps the canine to escape to the owners. In the later film, Lockhart played the now adult version.
The affectionate way in which she handled both Lassie and her offspring, Laddie, protagonist of a wartime story in Nazi-occupied Norway, was in the minds of the creators when it came to casting the Lassie TV series 13 years later.
Television and Stage Career
Although she was offered major roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her film career was stagnating and that television 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 rural hotel, where Lockhart is a doctor 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 busy workload continued for the next five decades, with a regular role in General Hospital between 1984 and 1998. Among her many one-off appearances were as herself in a 1988 episode of a talkshow, where the presenter finds a stray collie, and in another sitcom in 1995 as the parent of a restaurant manager.
Final Roles and Contributions
Her last TV credit came in 2021 as the narration of Alpha Control in an episode of a streaming service’s remake of Lost in Space. In the movie version starring famous 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 volunteer spokesperson brought her its prestigious award.
Among her few subsequent feature films was the fantasy, Troll (1986) in which she portrayed a sorceress, with her own daughter, Anne Lockhart, playing her earlier self.
Private Details
In 1951 she married John Maloney, a physician and former Navy medical officer. In addition to Anne, they had another daughter, June. That marriage ended in divorce, as did her subsequent marriage, to John Lindsay, an designer.
She is remembered by her daughters and four grandkids.
