Launching her career in films, June Lockhart, who died aged 100, achieved her greatest success after shifting largely to television. Having been given limited chances to excel in films from her first appearance as a child in 1938 until 1947, she thrived on TV in numerous beloved series, especially in Lassie.
Her Iconic Role in Lassie
Taking over from another actress in 1958, Lockhart continued in the series until 1964. Her role was Ruth Martin, wed to agriculturalist Paul Martin and the adoptive mother of young Timmy Martin, whose collie was the titular star of the series.
Despite playing a housewife, Lockhart adeptly avoided being overshadowed by the smart animal star. She characterized the show as “a fantasy about families on a farm in which the dog resolves all the problems in 22 minutes, in time for the last advertisement”. After she left the show, Lockhart remarked: “In six chaste years of playing a country wife and parent, I was rarely permitted to kiss my on-screen husband on the cheek.”
Adventure into Lost in Space
Lockhart went straight into another hit, Lost in Space (1965-68), a partly comedic science fiction series targeted primarily at young audiences and inspired by The Swiss Family Robinson. Lockhart and another actor portrayed Maureen and John Robinson, two researchers exploring distant planets. Lockhart had to spend the majority of her time deftly trying to navigate visual effects. As the show progressed, the storyline became increasingly less about this space family and more about the boy and his bond with a robot, and the timid antagonist Dr Zachary Smith.
Early Career and Family Influence
Lockhart’s feature film first role, 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 performers in dozens 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-singing role in an musical production at the Metropolitan Opera in New York (1931).
Move to Hollywood and Movie Roles
When her parent was given a deal by a motion picture studio, after his acclaim on Broadway, she moved with her parents to Hollywood, where Gene made around 300 films. After going to school in Beverly Hills, June started 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 last one, she is delightful 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 several sequels to the extremely successful Lassie Come Home (1943), in which a young star had played the girl who assists the dog to escape to the family. In the later film, Lockhart played the now grown-up version.
The affectionate way in which she handled both Lassie and her son, Laddie, protagonist of a wartime story in Nazi-occupied Norway, was in the consideration of the producers when it came to selecting the Lassie TV series 13 years later.
Shift to Television and Broadway Success
Although she was offered leading roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her film career was getting her nowhere and that television 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 further substantial run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a physician 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 workload continued for the next five decades, with a recurring role in General Hospital between 1984 and 1998. Among her many one-off appearances were as herself in a 1988 episode of a talkshow, where the host finds a stray collie, and in another sitcom in 1995 as the mother of a restaurant manager.
Later Roles and Achievements
Her last TV credit came in 2021 as the narration of Alpha Control in an episode of a digital platform’s new version of Lost in Space. In the big screen version featuring famous actors (1998), she had a digital cameo as a school principal. She took joy in learning how much of an influence 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 volunteer spokesperson 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 Life and Family
In 1951 she married John Maloney, a physician and former Navy doctor. In addition to Anne, they had a second daughter, June. That union ended in divorce, as did her subsequent marriage, to John Lindsay, an architect.
She is survived by her children and four grandchildren.
