June Lockhart, who passed away at the remarkable age of 100, began her professional journey in films, but gained fame after moving almost entirely to television. Having been offered few chances to shine in movies from her first appearance as a child in 1938 until 1947, she excelled on television in many popular series, most notably in Lassie.
Portraying Ruth Martin on Lassie
Taking over from a previous star in 1958, Lockhart continued in the show until 1964. Her role was Ruth Martin, married to agriculturalist Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose dog was the titular star of the series.
In her role as a housewife, Lockhart somehow managed to avoid being completely upstaged by the intelligent dog. She described the show as “a fairy tale about families on a rural property in which the canine resolves all the issues in 22 minutes, in time for the last commercial”. After she departed the show, Lockhart remarked: “In six chaste years of playing a rural wife and mother, I was hardly ever permitted to kiss my co-star on the face.”
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 mostly at young audiences and inspired 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 skillfully trying to navigate visual effects. As the show continued, the storyline became increasingly less about this interstellar clan and increasingly about the boy and his bond with a mechanical being, and the timid antagonist 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 parents, 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 dozens of films, as well as on stage, it was nearly certain that June, who was born in New York, would join 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).
Move to Hollywood and Film Roles
When her parent was offered a contract by a motion picture studio, after his success on Broadway, she moved with her parents to Hollywood, where Gene made approximately 300 films. After attending school in Beverly Hills, June began her professional life in movies, 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 household party, whose schedule is arranged spitefully to stop Lockhart dancing with her brother.
More significantly, although she did not know it at the time, was Son of Lassie (1945). It was one of multiple sequels to the extremely successful Lassie Come Home (1943), in which a young star had played the female character who helps the canine to escape to the owners. In the later film, Lockhart played the now grown-up character.
The affectionate way in which she interacted with both Lassie and her offspring, Laddie, hero of a wartime adventure in enemy-held Norway, was in the consideration of the producers when it came to selecting the Lassie TV series 13 years later.
Television and Stage Career
Although she was given 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 television would be the answer. Before going in a different direction, she received praise on Broadway in For Love or Money (1947), a comedy for which she won a Tony award as most promising newcomer.
A additional substantial run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a doctor and mother figure. She also appeared 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 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 comedy series, where the host finds a stray collie, and in another sitcom in 1995 as the parent of a restaurant manager.
Final Roles and Achievements
Her last TV credit came in 2021 as the narration of Alpha Control in an episode of a streaming service’s new version of Lost in Space. In the big screen version featuring famous actors (1998), she had a holographic cameo as a school principal. She took pleasure in learning how much of an influence the first series had been to later astronauts, and often participated in the agency’s launches and other events. In 2013 her work as a volunteer representative brought her its prestigious award.
Among her few later feature films was the fantasy, Troll (1986) in which she played a witch, with her own daughter, Anne Lockhart, playing her earlier self.
Personal Information
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 separation, as did her second marriage, to John Lindsay, an designer.
She is remembered by her daughters and four grandchildren.
