Launching her career in films, June Lockhart, who died aged 100, achieved her greatest success after shifting largely to the small screen. Having been offered few opportunities to excel in movies from her debut as a child in 1938 until 1947, she thrived on TV in numerous beloved series, most notably in Lassie.
Her Iconic Role in Lassie
Taking over from another actress in 1958, Lockhart continued in the series until 1964. She played Ruth Martin, married to agriculturalist Paul Martin and the adoptive mother of young Timmy Martin, whose dog was the eponymous star of the series.
Despite playing a housewife, Lockhart adeptly avoided being overshadowed by the brilliant animal star. She described the show as “a fantasy about people on a farm in which the dog resolves all the problems in 22 minutes, in time for the last advertisement”. After she departed the show, Lockhart remarked: “In six chaste years of playing a rural spouse and mother, I was rarely allowed to kiss my co-star on the face.”
Journey into Lost in Space
Lockhart went straight into another successful series, Lost in Space (1965-68), a semi-spoof science fiction series aimed mostly at children and inspired by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two researchers exploring alien planets. Lockhart had to spend the majority of her time skillfully trying to navigate visual effects. As the series progressed, the narrative became increasingly less about this space family and more about the young son and his bond with a robot, and the cowardly villain Dr Zachary Smith.
Start in Show Business
Lockhart’s feature film first role, 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 Canada-native Gene were both performers in many of films, as well as on stage, it was nearly inevitable that June, who was born in New York, would join the entertainment industry.
Her first stage 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).
Move to Hollywood and Film Roles
When her parent was offered a deal by a motion picture studio, after his success on Broadway, she relocated with her family to Hollywood, where Gene made around 300 films. After attending school in Beverly Hills, June started her professional life in films, mostly in small roles in prestigious 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 family party, whose dance card is filled spitefully to prevent Lockhart interacting with her sibling.
More significantly, although she did not realize it at the time, was Son of Lassie (1945). It was one of multiple follow-ups to the hugely successful Lassie Come Home (1943), in which another actress had played the girl who assists the dog to escape to the owners. 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 consideration of the producers when it came to casting the Lassie TV series 13 years later.
Shift to Television and Stage Success
Although she was given 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 TV 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 most promising newcomer.
A further significant run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a doctor and maternal character. She also featured frequently in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic 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 herself in a 1988 episode of a comedy series, where the presenter finds a stray collie, and in another sitcom in 1995 as the mother of a dining manager.
Final Career and Impact
Her last TV credit came in 2021 as the voice of Alpha Control in an episode of a streaming service’s remake of Lost in Space. In the movie version featuring famous actors (1998), she had a holographic cameo as a school principal. She took pleasure in learning how much of an influence the original series had been to future astronauts, and often participated in the agency’s launches and other events. In 2013 her work as a volunteer 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 married 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 architect.
She is remembered by her children and four grandkids.
