June Lockhart, who died at the remarkable age of 100, began her professional journey in movies, but gained recognition after moving almost exclusively to television. Having been offered few chances to excel in movies from her debut as a youngster in 1938 until 1947, she excelled on TV in numerous popular series, most notably in Lassie.
Her Memorable Role in Lassie
Stepping in from another actress in 1958, Lockhart continued in the series until 1964. Her role was Ruth Martin, married to farmer Paul Martin and the foster mother of young Timmy Martin, whose dog was the eponymous star of the series.
In her part as a homemaker, Lockhart somehow succeeded to avoid being totally overshadowed by the intelligent canine. She described the show as “a fantasy about families on a rural property in which the dog resolves all the problems in 22 minutes, in time for the last advertisement”. After she departed the show, Lockhart remarked: “In six chaste years of playing a country spouse and mother, I was hardly ever permitted to peck my on-screen husband on the face.”
Featuring in Lost in Space
Lockhart went directly into another successful series, Lost in Space (1965-68), a semi-spoof sci-fi series aimed mostly at children 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 the majority of her time skillfully trying to survive visual effects. As the series continued, the storyline became less and less about this interstellar family and more about the boy and his friendship with a mechanical being, and the cowardly antagonist Dr Zachary Smith.
Early Career and Family Influence
Lockhart’s movie debut, at the age of 13, had come as Belinda Cratchit in A Christmas Carol (1938). In the roles of her mother and father, Bob and Mrs Cratchit, were her real-life parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canadian-born Gene were both performers in many of films, as well as on theater, it was almost inevitable that June, who was born in New York, would enter show business.
Her first theatrical performance, at the tender age of six, came in a non-singing role in an opera at the Metropolitan Opera in New York (1931).
Hollywood Work
When her parent was given a contract by a motion picture studio, after his success on Broadway, she relocated with her parents to Hollywood, where Gene made approximately 300 films. After attending school in Beverly Hills, June started her professional life in films, mostly in small 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 schedule is filled spitefully to prevent Lockhart dancing with her sibling.
More significantly, although she did not know it at the time, was Son of Lassie (1945). It was one of several sequels to the hugely successful Lassie Come Home (1943), in which a young star had played the girl who assists the dog to return to the owners. In the subsequent film, Lockhart played the now grown-up character.
The loving way in which she handled both Lassie and her offspring, Laddie, hero of a wartime adventure 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 suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her film career was getting her nowhere and that TV would be the answer. Before embarking in a different direction, she received praise 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 rural 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 guest appearances were as the actress 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 restaurant manager.
Later Roles and Contributions
Her final TV appearance came in 2021 as the voice of Alpha Control in an episode of a streaming service’s remake of Lost in Space. In the big screen version featuring famous actors (1998), she had a holographic cameo as a school principal. She took joy 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 volunteer representative 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 earlier self.
Personal Details
In 1951 she wed John Maloney, a doctor 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 architect.
She is remembered by her children and four grandkids.
