June Lockhart, who died at the age of 100, began her professional journey in movies, but achieved fame after moving almost entirely to television. Having been offered limited chances to shine in movies from her first appearance as a youngster in 1938 until 1947, she excelled 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 seven-year-old Timmy Martin, whose dog was the eponymous hero of the series.
In her part as a homemaker, Lockhart somehow succeeded to avoid being completely overshadowed by the intelligent dog. She described the show as “a fantasy about people on a farm in which the dog solves all the issues in 22 minutes, in time for the last advertisement”. After she left the show, Lockhart remarked: “In six sexless years of playing a rural wife and parent, I was hardly ever allowed to kiss my co-star on the cheek.”
Adventure into Lost in Space
Lockhart went directly into a second hit, Lost in Space (1965-68), a partly comedic sci-fi series aimed primarily at children and inspired by The Swiss Family Robinson. Lockhart and her co-star played Maureen and John Robinson, two scientists exploring distant planets. Lockhart had to spend most of her time deftly trying to navigate visual effects. As the series continued, the narrative became increasingly less about this interstellar clan and increasingly about the boy and his bond with a mechanical being, and the timid villain Dr Zachary Smith.
Initial Career and Family Background
Lockhart’s movie first role, 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 real-life parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canada-native Gene were both performers in dozens of films, as well as on theater, it was nearly inevitable that June, who was born in New York, would enter show business.
Her first theatrical appearance, at the age of six, came in a non-musical role in an musical production at the Metropolitan Opera in New York (1931).
Hollywood Career
When her parent was given a deal by a motion picture studio, after his acclaim on Broadway, she moved with her family 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 latter, she is delightful as a New Yorker at a family party, whose schedule is filled maliciously to prevent Lockhart dancing with her brother.
More importantly, 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 helps the canine to return to the owners. In the subsequent film, Lockhart played the now adult character.
The affectionate way in which she interacted with both Lassie and her son, Laddie, protagonist of a wartime story in enemy-held Norway, was in the minds of the producers when it came to casting the Lassie TV series 13 years later.
Transition to Television and Broadway Success
Although she was offered major roles in two suspense films, 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 going 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 best newcomer.
A additional significant 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 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 recurring 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 presenter finds a lost collie, and in another sitcom in 1995 as the mother of a dining manager.
Final Roles and Contributions
Her final 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 featuring well-known actors (1998), she had a digital cameo as a school principal. She took pleasure in learning how much of an inspiration the original series had been to future astronauts, and often attended the agency’s launches and other events. In 2013 her work as a unpaid spokesperson brought her its prestigious award.
Among her few later feature films was the fantasy, Troll (1986) in which she portrayed a sorceress, with her own daughter, Anne Lockhart, playing her younger self.
Personal Life and Family
In 1951 she wed John Maloney, a doctor and former Navy medical officer. In addition to Anne, they had a second daughter, June. That union ended in separation, as did her subsequent marriage, to John Lindsay, an architect.
She is survived by her daughters and four grandchildren.
