Starting her career in films, June Lockhart, who passed on aged 100, found her biggest success after switching predominantly to television. Having been given few opportunities to shine in films from her debut as a youngster in 1938 until 1947, she excelled on TV in many beloved 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 farmer Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose collie was the titular star of the series.
In her role as a homemaker, Lockhart somehow succeeded to avoid being totally overshadowed by the clever canine. She characterized the program as “a fantasy about people on a farm in which the dog resolves all the problems in 22 minutes, in time for the last commercial”. After she departed the show, Lockhart remarked: “In six chaste years of playing a country spouse and parent, I was rarely allowed to kiss my on-screen husband on the cheek.”
Featuring in Lost in Space
Lockhart went straight into a second hit, Lost in Space (1965-68), a partly comedic science fiction series aimed primarily at children and based by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two scientists exploring alien planets. Lockhart had to spend most of her time deftly trying to navigate special 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 cowardly antagonist Dr Zachary Smith.
Start in Entertainment
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 actors in dozens of films, as well as on theater, it was almost certain that June, who was born in New York, would join show business.
Her first theatrical appearance, at the age of six, came in a non-singing role in an musical production at the Metropolitan Opera in New York (1931).
Transition to Hollywood and Film Roles
When her parent 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 started 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 last one, she is charming as a New Yorker at a family party, whose dance card is filled maliciously to stop Lockhart dancing with her brother.
More importantly, although she did not realize 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 girl who assists the dog to return to the owners. In the subsequent film, Lockhart played the now grown-up version.
The loving way in which she handled both Lassie and her offspring, Laddie, hero of a World War II story in enemy-held Norway, was in the minds of the creators when it came to casting the Lassie TV series 13 years later.
Shift to Television and Stage Success
Although she was given major roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her movie career was getting her nowhere and that television would be the answer. Before embarking 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 further significant run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a physician and maternal character. She also appeared frequently in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy schedule persisted 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 talkshow, where the host finds a lost collie, and in another sitcom in 1995 as the mother of a dining manager.
Later Career and Legacy
Her last TV credit came in 2021 as the voice of Alpha Control in an episode of a streaming service’s remake of Lost in Space. In the movie version featuring famous actors (1998), she had a digital cameo as a school principal. She took joy in learning how much of an inspiration the first series had been to future astronauts, and often attended the organization’s launches and other events. In 2013 her work as a volunteer spokesperson brought her its prestigious award.
Among her limited 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 Information
In 1951 she wed John Maloney, a physician and former Navy doctor. In addition to Anne, they had another daughter, June. That marriage ended in separation, as did her subsequent marriage, to John Lindsay, an architect.
She is remembered by her children and four grandkids.
