Launching her career in films, June Lockhart, who passed on aged 100, achieved her biggest success after switching predominantly to television. Having been given limited opportunities to excel in films from her debut as a child in 1938 until 1947, she excelled on TV in numerous popular series, especially in Lassie.
Her Iconic Role in Lassie
Stepping in from another actress in 1958, Lockhart remained in the series until 1964. Her role was Ruth Martin, wed to farmer Paul Martin and the adoptive mother of young Timmy Martin, whose collie was the titular hero of the series.
Even with playing a housewife, Lockhart adeptly avoided being outshone by the brilliant animal star. She described the program as “a fantasy about people 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 chaste years of playing a country spouse and mother, I was rarely permitted to peck my co-star on the face.”
Starring in Lost in Space
Lockhart went directly into a second hit, Lost in Space (1965-68), a partly comedic sci-fi series targeted primarily at young audiences and inspired by The Swiss Family Robinson. Lockhart and her co-star portrayed Maureen and John Robinson, two scientists exploring distant planets. Lockhart had to spend most of her time deftly trying to survive special effects. As the series continued, the narrative became less and less about this space family and more about the young son and his bond with a robot, and the cowardly antagonist 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 parents, Bob and Mrs Cratchit, were her real-life parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canada-native Gene were both actors 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 theatrical appearance, at the 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 Movie Roles
When her parent was given 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 began her professional life in films, mostly 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 household party, whose dance card is filled spitefully to prevent Lockhart dancing with her brother.
More importantly, although she did not know it at the time, was Son of Lassie (1945). It was one of multiple follow-ups to the extremely successful Lassie Come Home (1943), in which a young star had played the female character who helps the canine to escape to the family. 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 World War II story in Nazi-occupied Norway, was in the minds of the creators when it came to casting the Lassie TV series 13 years later.
Television and Theater Career
Although she was given leading roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her movie career was stagnating and that TV would be the solution. Before embarking in a new direction, she won praise on Broadway in For Love or Money (1947), a humorous play 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 mother figure. She also appeared regularly in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy 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 dining manager.
Final Career and Impact
Her last 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 movie version starring famous 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 future astronauts, and often participated in the organization’s launches and other events. In 2013 her work as a volunteer spokesperson brought her its Exceptional Public Achievement Medal.
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 physician and former Navy medical officer. In addition to Anne, they had another daughter, June. That marriage ended in divorce, as did her subsequent marriage, to John Lindsay, an designer.
She is remembered by her daughters and four grandchildren.
