June Lockhart, who died at the remarkable age of 100, began her professional journey in movies, but achieved fame after transitioning almost entirely to TV. Having been given limited opportunities to shine in films from her first appearance as a youngster 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 continued in the series until 1964. She played 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 part as a homemaker, Lockhart somehow succeeded to avoid being totally overshadowed by the intelligent canine. She described 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 show, Lockhart commented: “In six chaste years of playing a rural wife and mother, I was rarely allowed to peck my co-star on the cheek.”
Adventure into Lost in Space
Lockhart went directly into another successful series, Lost in Space (1965-68), a semi-spoof science fiction series targeted mostly at children and based by The Swiss Family Robinson. Lockhart and her co-star played Maureen and John Robinson, two researchers exploring distant planets. Lockhart had to spend the majority of her time skillfully trying to survive special effects. As the series progressed, the narrative became increasingly less about this space clan and more about the young son and his bond with a mechanical being, and the timid antagonist Dr Zachary Smith.
Beginnings in Entertainment
Lockhart’s movie 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 real-life parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canada-native Gene were both performers in many of movies, as well as on stage, it was nearly inevitable that June, who was born in New York, would join show business.
Her first theatrical appearance, at the tender age of six, came in a non-singing role in an opera at the Metropolitan Opera in New York (1931).
Hollywood Career
When her father was offered a deal by a motion picture 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 began her professional life in movies, mainly in minor 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 charming as a New Yorker at a household party, whose schedule is arranged spitefully to prevent 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 follow-ups to the extremely successful Lassie Come Home (1943), in which another actress had played the female character who assists the dog to return to the family. In the later film, Lockhart played the now adult version.
The loving way in which she handled both Lassie and her son, Laddie, hero of a wartime adventure in Nazi-occupied Norway, was in the consideration of the producers when it came to casting the Lassie TV series 13 years later.
Shift to Television and Broadway Success
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 getting her nowhere and that television would be the solution. Before embarking in a new 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 doctor 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 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 comedy series, where the host finds a stray collie, and in another sitcom in 1995 as the mother of a dining manager.
Later Roles and Achievements
Her final TV appearance came in 2021 as the voice of Alpha Control in an episode of a digital platform’s new version of Lost in Space. In the big screen version featuring well-known 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 future 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 subsequent feature films was the fantasy, Troll (1986) in which she portrayed a sorceress, with her own daughter, Anne Lockhart, playing her younger self.
Personal Life and Family
In 1951 she married 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 grandchildren.
