Launching her career in films, June Lockhart, who passed on aged 100, achieved her biggest success after shifting largely to television. Having been given limited opportunities to shine in films from her debut as a child in 1938 until 1947, she thrived on television in many popular series, most notably in Lassie.
Her Memorable Role in Lassie
Stepping in from another actress in 1958, Lockhart continued in the show until 1964. Her role was Ruth Martin, married to farmer Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose collie was the titular hero of the series.
In her role as a homemaker, Lockhart somehow succeeded to avoid being totally overshadowed by the clever canine. She described the show 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 series, Lockhart commented: “In six sexless years of playing a rural wife and parent, I was rarely allowed to peck my on-screen husband on the face.”
Starring in Lost in Space
Lockhart went directly into a second successful series, Lost in Space (1965-68), a semi-spoof sci-fi series targeted primarily at young audiences and based by The Swiss Family Robinson. Lockhart and another actor portrayed Maureen and John Robinson, two researchers investigating alien planets. Lockhart had to spend the majority of her time deftly trying to navigate visual effects. As the series continued, the storyline became less and less about this interstellar clan and more about the young son and his friendship with a robot, and the cowardly villain Dr Zachary Smith.
Early Career and Family Influence
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 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 join the entertainment industry.
Her first theatrical performance, at the age of six, came in a non-singing role in an musical production at the Metropolitan Opera in New York (1931).
Cinema Career
When her parent was given a deal by a film studio, after his acclaim on Broadway, she moved with her family to Hollywood, where Gene made around 300 films. After going to school in Beverly Hills, June began her professional life in films, 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 charming as a New Yorker at a household party, whose dance card is filled spitefully 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 hugely successful Lassie Come Home (1943), in which another actress had played the girl who assists the canine to escape to the owners. In the later film, Lockhart played the now adult character.
The loving way in which she interacted with both Lassie and her son, Laddie, hero of a wartime adventure in Nazi-occupied Norway, was in the consideration of the creators when it came to selecting the Lassie TV series 13 years later.
Television and Theater Work
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 television would be the answer. Before embarking in a new direction, she won praise on Broadway in For Love or Money (1947), a comedy for which she won a Tony award as most promising newcomer.
A additional significant run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a doctor and mother figure. She also featured frequently in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic workload persisted for the next five decades, with a regular role in General Hospital between 1984 and 1998. Among her many guest appearances were as the actress in a 1988 episode of a comedy series, where the presenter finds a lost collie, and in another sitcom in 1995 as the parent of a restaurant manager.
Final Career and Legacy
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 well-known actors (1998), she had a digital cameo as a school principal. She took joy in learning how much of an influence the first series had been to later astronauts, and often attended the organization’s launches and other events. In 2013 her work as a unpaid spokesperson brought her its Exceptional Public Achievement Medal.
Among her few later feature films was the fantasy, Troll (1986) in which she played a witch, with her own daughter, Anne Lockhart, playing her younger self.
Personal Life and Family
In 1951 she wed John Maloney, a doctor and former Navy medical officer. In addition to Anne, they had a second daughter, June. That marriage ended in divorce, as did her second marriage, to John Lindsay, an architect.
She is remembered by her daughters and four grandkids.
