Launching her career in cinema, June Lockhart, who died aged 100, found her biggest success after shifting predominantly to the small screen. Having been offered few opportunities to shine in movies from her first appearance as a youngster in 1938 until 1947, she excelled on TV in numerous popular series, especially in Lassie.
Her Iconic Role in Lassie
Stepping in from a previous star in 1958, Lockhart remained in the series until 1964. She played Ruth Martin, wed to farmer Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose collie was the eponymous hero of the series.
In her role as a housewife, Lockhart somehow succeeded to avoid being completely overshadowed by the intelligent dog. She characterized the show as “a fairy tale about families on a rural property in which the dog resolves 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 hardly ever permitted to peck my on-screen husband on the face.”
Starring in Lost in Space
Lockhart went directly into a second hit, Lost in Space (1965-68), a partly comedic science fiction series targeted mostly at young audiences and inspired by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two researchers investigating alien planets. Lockhart had to spend the majority of her time skillfully trying to navigate special effects. As the series continued, the narrative became increasingly less about this space family and more about the boy and his friendship with a mechanical being, and the cowardly villain Dr Zachary Smith.
Initial Career and Family Influence
Lockhart’s movie first role, at the 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 UK-native Kathleen and Canadian-born Gene were both performers in many of movies, as well as on stage, it was nearly certain that June, who was born in New York, would join the entertainment industry.
Her first theatrical 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).
Transition to Hollywood and Film Roles
When her parent was offered a contract by a motion picture studio, after his acclaim on Broadway, she relocated 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 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 filled spitefully to prevent Lockhart dancing 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 a young star had played the female character who assists the canine to escape to the owners. In the subsequent film, Lockhart played the now grown-up character.
The affectionate way in which she handled both Lassie and her son, Laddie, hero of a World War II story in Nazi-occupied Norway, was in the consideration of the creators when it came to selecting the Lassie TV series 13 years later.
Transition to Television and Stage Success
Although she was given 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 answer. Before embarking in a different direction, she received praise on Broadway in For Love or Money (1947), a comedy for which she won a Tony award as best newcomer.
A additional substantial run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a doctor and maternal character. She also featured regularly in TV cowboy shows 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 mother of a restaurant manager.
Later Roles and Contributions
Her last TV appearance came in 2021 as the voice of Alpha Control in an episode of a digital platform’s remake of Lost in Space. In the movie version starring 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 participated in the organization’s launches and other events. In 2013 her work as a volunteer representative brought her its Exceptional Public Achievement Medal.
Among her few subsequent 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 physician 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 designer.
She is remembered by her children and four grandchildren.
