June Lockhart, who died at the remarkable age of 100, started her professional journey in movies, but achieved fame after moving almost exclusively to TV. Having been given few chances to shine in movies from her first appearance as a child in 1938 until 1947, she excelled on television in many beloved series, most notably in Lassie.
Her Memorable Role in Lassie
Stepping in from another actress in 1958, Lockhart continued in the show until 1964. Her role was Ruth Martin, married to farmer Paul Martin and the foster mother of young Timmy Martin, whose collie was the titular hero of the series.
Even with playing a housewife, Lockhart skillfully avoided being overshadowed by the brilliant animal star. She described the program as “a fantasy about families on a farm in which the canine solves all the issues in 22 minutes, in time for the last commercial”. After she departed the series, Lockhart commented: “In six sexless years of playing a country wife and parent, I was hardly ever permitted to peck my co-star on the face.”
Adventure into Lost in Space
Lockhart went straight 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 her co-star played Maureen and John Robinson, two researchers investigating distant planets. Lockhart had to spend the majority of her time deftly trying to survive special effects. As the show continued, the narrative became less and less about this interstellar family and more about the boy and his bond with a robot, and the cowardly villain Dr Zachary Smith.
Initial Career and Family Background
Lockhart’s movie debut, at the young 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 actual parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canadian-born Gene were both actors in dozens of movies, as well as on stage, it was nearly inevitable that June, who was born in New York, would enter show business.
Her first theatrical appearance, at the tender age of six, came in a non-singing role in an opera at the Metropolitan Opera in New York (1931).
Hollywood Career
When her parent was offered a deal by a motion picture studio, after his acclaim on Broadway, she moved with her parents to Hollywood, where Gene made around 300 films. After attending school in Beverly Hills, June started her professional life in movies, mostly in minor roles in acclaimed pictures such as Sergeant York (1941), The White Cliffs of Dover (1942) and Meet Me in St Louis (1944). In the latter, she is delightful as a New Yorker at a family party, whose dance card is arranged spitefully to stop Lockhart dancing with her sibling.
More importantly, although she did not realize it at the time, was Son of Lassie (1945). It was one of multiple sequels to the extremely successful Lassie Come Home (1943), in which a young star had played the girl who assists the canine to escape to the family. In the subsequent film, Lockhart played the now grown-up version.
The loving way in which she handled both Lassie and her son, Laddie, protagonist of a wartime story in enemy-held Norway, was in the consideration of the creators when it came to selecting the Lassie TV series 13 years later.
Shift to Television and Stage Achievement
Although she was given major roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her film career was stagnating and that TV would be the answer. Before embarking in a different 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 further significant run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a physician and maternal character. She also appeared frequently in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy schedule 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 host finds a lost collie, and in another sitcom in 1995 as the parent of a dining manager.
Later Career and Legacy
Her final TV appearance came in 2021 as the voice of Alpha Control in an episode of a digital platform’s new version of Lost in Space. In the movie version starring well-known 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 participated in the agency’s launches and other events. In 2013 her work as a volunteer representative 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 earlier 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 designer.
She is survived by her daughters and four grandchildren.
