June Lockhart, who passed away at the age of 100, started her professional journey in films, but achieved fame after moving almost exclusively to television. Having been given few opportunities to excel in movies from her first appearance as a youngster in 1938 until 1947, she thrived on television in numerous beloved series, most notably in Lassie.
Her Iconic Role in Lassie
Taking over from a previous star in 1958, Lockhart continued in the series until 1964. Her role was Ruth Martin, married to agriculturalist 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 managed to avoid being totally overshadowed by the intelligent dog. She characterized the show as “a fairy tale about people on a rural property in which the dog resolves all the problems in 22 minutes, in time for the last advertisement”. After she departed the series, Lockhart remarked: “In six sexless years of playing a rural spouse and parent, I was hardly ever allowed to peck my on-screen husband on the face.”
Adventure into Lost in Space
Lockhart went directly into another successful series, Lost in Space (1965-68), a partly comedic science fiction series aimed primarily at children and inspired by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two scientists exploring alien planets. Lockhart had to spend the majority of her time skillfully trying to navigate special effects. As the show progressed, the storyline became less and less about this space family and increasingly about the boy and his bond with a mechanical being, and the cowardly villain Dr Zachary Smith.
Beginnings in Entertainment
Lockhart’s feature film debut, 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 movies, as well as on stage, it was nearly inevitable 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 father was offered 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 started her career 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 last one, she is charming as a New Yorker at a family party, whose schedule is filled spitefully to prevent Lockhart interacting with her brother.
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 a young star had played the girl who helps the canine to escape to the owners. In the later film, Lockhart played the now grown-up version.
The loving way in which she interacted with both Lassie and her offspring, Laddie, protagonist of a World War II adventure in enemy-held Norway, was in the minds of the producers when it came to selecting the Lassie TV series 13 years later.
Shift to Television and Broadway Success
Although she was given major roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her movie career was getting her nowhere and that television would be the answer. Before going 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 substantial run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a physician 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 busy workload continued 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 talkshow, where the host finds a stray collie, and in another sitcom in 1995 as the mother of a dining manager.
Later Roles and Contributions
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 starring well-known actors (1998), she had a digital cameo as a school principal. She took joy in learning how much of an inspiration the original series had been to later astronauts, and often participated in the organization’s launches and other events. In 2013 her work as a volunteer representative brought her its prestigious award.
Among her limited later 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 married John Maloney, a doctor and former Navy doctor. In addition to Anne, they had another daughter, June. That marriage ended in separation, as did her second marriage, to John Lindsay, an architect.
She is remembered by her daughters and four grandchildren.
