Starting her career in cinema, June Lockhart, who died aged 100, achieved her biggest success after switching largely to television. Having been offered limited opportunities to excel in films from her first appearance as a youngster in 1938 until 1947, she thrived on TV in numerous beloved series, most notably in Lassie.
Her Memorable Role in Lassie
Taking over from another actress in 1958, Lockhart continued in the show until 1964. She played Ruth Martin, married to agriculturalist Paul Martin and the adoptive mother of young Timmy Martin, whose collie was the titular hero of the series.
Despite playing a mother figure, Lockhart skillfully avoided being overshadowed by the smart dog. She described the show as “a fairy tale about people on a rural property in which the canine solves all the problems in 22 minutes, in time for the last commercial”. After she left the show, Lockhart commented: “In six chaste years of playing a country wife and mother, I was rarely permitted to kiss my on-screen husband on the cheek.”
Featuring in Lost in Space
Lockhart went straight into a second successful series, Lost in Space (1965-68), a partly comedic science fiction series aimed primarily at young audiences and inspired by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two researchers investigating distant planets. Lockhart had to spend most of her time skillfully trying to navigate visual effects. As the series progressed, the narrative became less and less about this space family and more about the boy and his friendship with a mechanical being, and the cowardly villain Dr Zachary Smith.
Start in Entertainment
Lockhart’s movie 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 British-born Kathleen and Canada-native Gene were both performers in dozens of movies, as well as on stage, it was almost inevitable that June, who was born in New York, would enter the entertainment industry.
Her first theatrical performance, at the tender 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 Movie Roles
When her parent was given a contract by a film studio, after his success on Broadway, she relocated with her family 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 schedule is arranged maliciously to stop Lockhart dancing with her sibling.
More importantly, 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 dog to escape to the family. In the subsequent film, Lockhart played the now adult version.
The loving way in which she handled both Lassie and her offspring, Laddie, hero of a World War II adventure in Nazi-occupied Norway, was in the minds of the producers when it came to selecting the Lassie TV series 13 years later.
Shift to Television and Broadway Achievement
Although she was offered major roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her film career was stagnating and that TV would be the solution. Before embarking in a different direction, she won acclaim on Broadway in For Love or Money (1947), a comedy 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 regularly in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic schedule persisted for the next five decades, with a regular role in General Hospital between 1984 and 1998. Among her many one-off appearances were as herself in a 1988 episode of a comedy series, where the host finds a lost collie, and in another sitcom in 1995 as the mother of a restaurant manager.
Final Career and Impact
Her final TV appearance 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 joy in learning how much of an influence the original series had been to later astronauts, and often attended the agency’s launches and other events. In 2013 her work as a volunteer spokesperson brought her its Exceptional Public Achievement Medal.
Among her limited later feature films was the fantasy, Troll (1986) in which she portrayed a sorceress, with her own daughter, Anne Lockhart, playing her younger self.
Personal Details
In 1951 she married John Maloney, a doctor and former Navy medical officer. In addition to Anne, they had a second daughter, June. That union ended in divorce, as did her second marriage, to John Lindsay, an designer.
She is remembered by her children and four grandchildren.
