Starting her career in films, June Lockhart, who passed on aged 100, achieved her greatest success after switching predominantly to television. Having been given few chances to excel in movies from her debut as a child in 1938 until 1947, she excelled on television in many popular series, most notably in Lassie.
Her Iconic Role in Lassie
Taking over from another actress in 1958, Lockhart remained in the series until 1964. Her role was Ruth Martin, married to farmer Paul Martin and the foster mother of young Timmy Martin, whose dog was the titular hero of the series.
In her part as a housewife, Lockhart somehow succeeded to avoid being completely overshadowed by the intelligent dog. She described the show as “a fairy tale about families on a farm in which the canine resolves 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 spouse and parent, I was hardly ever permitted to peck my on-screen husband on the cheek.”
Starring in Lost in Space
Lockhart went straight into another successful series, Lost in Space (1965-68), a partly comedic sci-fi series targeted primarily at children and inspired 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 navigate special effects. As the series progressed, the narrative became less and less about this interstellar clan and increasingly about the boy and his friendship with a mechanical being, and the cowardly antagonist Dr Zachary Smith.
Initial Career and Family Background
Lockhart’s movie first role, at the young 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 Canada-native 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 join the entertainment industry.
Her first theatrical appearance, at the tender age of six, came in a non-musical role in an musical production at the Metropolitan Opera in New York (1931).
Move to Hollywood and Movie Roles
When her father was given 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 attending school in Beverly Hills, June began her professional life in movies, mainly 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 latter, she is delightful as a New Yorker at a household party, whose schedule is filled spitefully to stop Lockhart dancing with her sibling.
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 a young star had played the girl who helps the canine to escape to the family. In the subsequent film, Lockhart played the now grown-up version.
The affectionate way in which she handled both Lassie and her offspring, Laddie, protagonist of a World War II story in enemy-held 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 suspense films, 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 going 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 most promising newcomer.
A further significant run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a physician 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 busy workload continued for the following five decades, with a regular role in General Hospital between 1984 and 1998. Among her many guest appearances were as herself in a 1988 episode of a talkshow, where the presenter finds a lost collie, and in another sitcom in 1995 as the mother of a restaurant manager.
Final Roles and Achievements
Her final 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 big screen version featuring famous actors (1998), she had a holographic cameo as a school principal. She took pleasure in learning how much of an inspiration the first series had been to later astronauts, and often attended the agency’s launches and other events. In 2013 her work as a volunteer representative 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 wed John Maloney, a doctor and former Navy doctor. In addition to Anne, they had another daughter, June. That marriage ended in divorce, as did her second marriage, to John Lindsay, an designer.
She is remembered by her children and four grandchildren.
