June Lockhart, who passed away at the age of 100, started her professional journey in movies, but achieved fame after transitioning almost exclusively to TV. Having been offered few chances to shine in movies from her debut as a youngster in 1938 until 1947, she thrived on TV in numerous beloved series, especially in Lassie.
Her Iconic Role in Lassie
Taking over from a previous star in 1958, Lockhart remained in the series until 1964. She played Ruth Martin, married to agriculturalist Paul Martin and the adoptive mother of young Timmy Martin, whose collie was the eponymous hero of the series.
Even with playing a housewife, Lockhart adeptly avoided being outshone by the smart dog. She characterized the show as “a fairy tale about people on a farm in which the dog resolves all the issues in 22 minutes, in time for the last commercial”. After she left the series, Lockhart remarked: “In six sexless years of playing a country wife and parent, I was rarely allowed to kiss my co-star on the cheek.”
Starring in Lost in Space
Lockhart went straight into another successful series, Lost in Space (1965-68), a partly comedic science fiction series targeted primarily at children and inspired by The Swiss Family Robinson. Lockhart and another actor portrayed Maureen and John Robinson, two researchers investigating distant planets. Lockhart had to spend the majority of her time skillfully trying to survive special effects. As the series progressed, the storyline became less and less about this interstellar family and more about the young son and his friendship with a mechanical being, and the timid villain Dr Zachary Smith.
Early Career and Family Influence
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 UK-native Kathleen and Canada-native Gene were both actors in many of films, as well as on theater, it was almost inevitable that June, who was born in New York, would join show business.
Her first stage appearance, at the age of six, came in a non-singing role in an opera at the Metropolitan Opera in New York (1931).
Transition to Hollywood and Movie Roles
When her father was offered a deal by a film studio, after his success on Broadway, she moved with her family to Hollywood, where Gene made around 300 films. After attending school in Beverly Hills, June began her professional life in movies, 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 know it at the time, was Son of Lassie (1945). It was one of several sequels to the extremely successful Lassie Come Home (1943), in which another actress had played the female character who helps the dog to escape to the family. In the later 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 adventure 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 leading roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her movie career was getting her nowhere and that TV would be the answer. Before embarking in a different 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 substantial 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 schedule persisted for the following five decades, with a recurring role in General Hospital between 1984 and 1998. Among her many guest 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 parent of a dining manager.
Final Roles and Achievements
Her final TV appearance came in 2021 as the voice of Alpha Control in an episode of a streaming service’s new version of Lost in Space. In the big screen version featuring famous actors (1998), she had a digital cameo as a school principal. She took pleasure in learning how much of an inspiration the first series had been to future astronauts, and often attended the organization’s launches and other events. In 2013 her work as a volunteer spokesperson brought her its prestigious award.
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 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 survived by her daughters and four grandkids.
