Launching her career in films, June Lockhart, who died aged 100, achieved her biggest success after switching largely to television. Having been given few chances to shine in movies from her debut as a youngster in 1938 until 1947, she thrived on television in many beloved series, most notably in Lassie.
Becoming Ruth Martin on Lassie
Taking over from a previous star in 1958, Lockhart remained in the series 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 titular star of the series.
In her role as a homemaker, Lockhart somehow managed to avoid being totally upstaged by the intelligent canine. She characterized the program as “a fairy tale about families on a rural property in which the canine solves all the issues in 22 minutes, in time for the last advertisement”. After she left the show, Lockhart commented: “In six chaste years of playing a country spouse and mother, I was hardly ever allowed to peck my on-screen husband on the cheek.”
Featuring in Lost in Space
Lockhart went straight into a second successful series, Lost in Space (1965-68), a semi-spoof science fiction series targeted primarily at young audiences and inspired by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two scientists exploring distant planets. Lockhart had to spend the majority of her time deftly trying to survive visual effects. As the series progressed, the narrative became less and less about this interstellar family and more about the boy and his bond with a robot, and the cowardly villain Dr Zachary Smith.
Beginnings in Show Business
Lockhart’s feature film debut, at the young 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 actual parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canada-native Gene were both performers in many of films, as well as on stage, it was almost certain that June, who was born in New York, would enter the entertainment industry.
Her first theatrical appearance, at the tender age of six, came in a non-musical role in an opera at the Metropolitan Opera in New York (1931).
Cinema Work
When her father was given a contract by a motion picture studio, after his success on Broadway, she relocated with her family to Hollywood, where Gene made approximately 300 films. After going to school in Beverly Hills, June began her career in movies, mostly in small 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 maliciously to prevent Lockhart dancing with her brother.
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 female character who assists the dog to return to the family. 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, protagonist of a World War II adventure in Nazi-occupied Norway, was in the minds of the producers 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 thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her movie career was getting her nowhere and that TV would be the solution. Before going in a new direction, she won acclaim on Broadway in For Love or Money (1947), a humorous play for which she won a Tony award as best newcomer.
A additional substantial 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 cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic schedule continued for the following 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 comedy series, where the presenter finds a stray collie, and in another sitcom in 1995 as the mother of a restaurant manager.
Later Career and Legacy
Her last TV credit came in 2021 as the voice of Alpha Control in an episode of a digital platform’s new version of Lost in Space. In the movie version featuring well-known actors (1998), she had a holographic cameo as a school principal. She took pleasure in learning how much of an inspiration the original series had been to later astronauts, and often participated in the organization’s launches and other events. In 2013 her work as a unpaid representative brought her its Exceptional Public Achievement Medal.
Among her limited subsequent feature films was the fantasy, Troll (1986) in which she played a sorceress, with her own daughter, Anne Lockhart, playing her earlier self.
Personal Details
In 1951 she wed John Maloney, a doctor and former Navy doctor. In addition to Anne, they had another daughter, June. That union ended in separation, as did her subsequent marriage, to John Lindsay, an architect.
She is remembered by her daughters and four grandkids.
