Starting her career in cinema, June Lockhart, who died aged 100, found her greatest success after switching largely to the small screen. Having been given limited opportunities to shine in films from her debut as a youngster in 1938 until 1947, she thrived on TV in numerous popular series, especially in Lassie.
Portraying Ruth Martin on Lassie
Taking over from a previous star in 1958, Lockhart remained in the series until 1964. Her role was Ruth Martin, married to farmer Paul Martin and the adoptive mother of young Timmy Martin, whose collie was the eponymous star of the series.
In her role as a homemaker, Lockhart somehow succeeded to avoid being totally overshadowed by the clever canine. She characterized the show as “a fairy tale about families on a farm in which the canine solves all the issues in 22 minutes, in time for the last commercial”. After she left the series, Lockhart commented: “In six sexless years of playing a country spouse and parent, I was rarely permitted to kiss my co-star on the face.”
Starring in Lost in Space
Lockhart went directly into a second successful series, Lost in Space (1965-68), a semi-spoof science fiction series aimed mostly at children and based by The Swiss Family Robinson. Lockhart and her co-star played Maureen and John Robinson, two scientists investigating distant planets. Lockhart had to spend the majority of her time skillfully trying to survive special effects. As the series continued, the storyline became less and less about this interstellar clan and increasingly about the young son and his bond with a robot, and the timid villain Dr Zachary Smith.
Early Career and Family Background
Lockhart’s feature film 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 actual parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canadian-born Gene were both performers in many of films, as well as on stage, it was almost inevitable that June, who was born in New York, would enter show business.
Her first stage performance, at the age of six, came in a non-musical role in an opera at the Metropolitan Opera in New York (1931).
Hollywood Career
When her father was offered a contract by a film studio, after his acclaim on Broadway, she relocated with her family to Hollywood, where Gene made approximately 300 films. After attending school in Beverly Hills, June started her professional life in movies, 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 delightful as a New Yorker at a family party, whose schedule is arranged spitefully 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 multiple sequels to the extremely successful Lassie Come Home (1943), in which a young star had played the girl who helps the dog to escape to the owners. In the subsequent film, Lockhart played the now adult version.
The loving way in which she interacted with both Lassie and her son, Laddie, hero of a wartime story in Nazi-occupied Norway, was in the consideration of the producers when it came to casting the Lassie TV series 13 years later.
Television and Theater Work
Although she was offered leading roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her movie career was getting her nowhere and that TV would be the solution. Before embarking in a different direction, she received acclaim 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 doctor and mother figure. She also appeared frequently in TV westerns 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 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 parent of a dining manager.
Later Roles and Contributions
Her last TV appearance 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 movie version starring well-known actors (1998), she had a digital cameo as a school principal. She took pleasure 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 few subsequent feature films was the fantasy, Troll (1986) in which she portrayed a witch, with her own daughter, Anne Lockhart, playing her earlier self.
Private Information
In 1951 she married John Maloney, a physician and former Navy doctor. 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 survived by her daughters and four grandchildren.
