June Lockhart, who died at the age of 100, began her career in movies, but achieved recognition after transitioning almost entirely to television. Having been offered limited opportunities to excel in films from her first appearance as a child in 1938 until 1947, she thrived on TV in numerous popular series, especially in Lassie.
Her Memorable Role in Lassie
Taking over from another actress in 1958, Lockhart remained in the series until 1964. Her role was Ruth Martin, wed to farmer Paul Martin and the adoptive mother of young Timmy Martin, whose collie was the eponymous hero of the series.
In her role as a homemaker, Lockhart somehow succeeded to avoid being completely overshadowed by the intelligent canine. She characterized the program as “a fantasy 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 departed the series, Lockhart commented: “In six chaste years of playing a country wife and parent, I was hardly ever allowed to peck my on-screen husband on the face.”
Adventure into Lost in Space
Lockhart went straight into another successful series, Lost in Space (1965-68), a semi-spoof sci-fi series aimed primarily at young audiences and inspired by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two researchers exploring alien planets. Lockhart had to spend most of her time skillfully trying to survive visual effects. As the show continued, the storyline became less and less about this interstellar family and increasingly about the young son and his friendship with a robot, and the cowardly antagonist Dr Zachary Smith.
Early Career and Family Influence
Lockhart’s feature film debut, at the 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 UK-native Kathleen and Canadian-born Gene were both performers in dozens of films, as well as on theater, it was nearly inevitable 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 Movie Roles
When her parent was offered a contract by a film studio, after his acclaim on Broadway, she moved with her parents to Hollywood, where Gene made approximately 300 films. After going to school in Beverly Hills, June started her career in films, mainly 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 household party, whose dance card 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 several sequels to the hugely successful Lassie Come Home (1943), in which a young star had played the girl who helps the canine to return to the owners. In the later film, Lockhart played the now adult version.
The affectionate way in which she interacted with both Lassie and her son, Laddie, protagonist of a wartime story in Nazi-occupied Norway, was in the consideration of the creators when it came to casting the Lassie TV series 13 years later.
Shift to Television and Broadway Achievement
Although she was offered major roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her movie 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 country hotel, where Lockhart is a physician and maternal character. She also appeared regularly in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic workload continued for the following five decades, with a recurring role in General Hospital between 1984 and 1998. Among her many one-off 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 parent of a dining manager.
Later Roles and Contributions
Her last TV credit came in 2021 as the voice of Alpha Control in an episode of a streaming service’s new version of Lost in Space. In the movie version featuring well-known actors (1998), she had a digital 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 attended the organization’s launches and other events. In 2013 her work as a unpaid spokesperson brought her its Exceptional Public Achievement Medal.
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 wed 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.
