June Lockhart, who passed away at the remarkable age of 100, started her professional journey in movies, but gained recognition after moving almost exclusively to TV. Having been offered few chances to shine in films from her first appearance as a child in 1938 until 1947, she thrived on television in numerous beloved series, especially in Lassie.
Her Iconic Role in Lassie
Taking over from a previous star in 1958, Lockhart continued in the series until 1964. She played Ruth Martin, married to agriculturalist Paul Martin and the foster mother of seven-year-old Timmy Martin, whose collie was the eponymous hero of the series.
In her part as a homemaker, Lockhart somehow managed to avoid being completely upstaged by the clever dog. She characterized the show as “a fairy tale about families on a farm in which the dog resolves all the issues in 22 minutes, in time for the last advertisement”. After she left the series, Lockhart commented: “In six sexless years of playing a country wife and mother, I was hardly ever permitted 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 semi-spoof sci-fi series aimed mostly at young audiences and inspired by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two researchers exploring alien planets. Lockhart had to spend the majority of her time skillfully trying to survive special effects. As the show progressed, the storyline became increasingly 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 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 parents, Bob and Mrs Cratchit, were her actual parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canada-native Gene were both performers in dozens of films, as well as on stage, it was almost 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-musical role in an musical production at the Metropolitan Opera in New York (1931).
Cinema Career
When her parent was offered a deal by a film studio, after his success on Broadway, she relocated with her parents to Hollywood, where Gene made around 300 films. After going to school in Beverly Hills, June started her professional life in films, 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 delightful as a New Yorker at a household party, whose dance card is filled spitefully to stop Lockhart interacting with her sibling.
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 another actress had played the girl who assists the canine to return to the owners. In the subsequent film, Lockhart played the now adult version.
The affectionate way in which she handled both Lassie and her son, Laddie, protagonist of a World War II story in Nazi-occupied Norway, was in the consideration 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 thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her movie career was getting her nowhere and that TV would be the answer. Before going in a new direction, she received acclaim on Broadway in For Love or Money (1947), a comedy for which she won a Tony award as best newcomer.
A further significant run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a doctor 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 hectic schedule 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 comedy series, where the presenter finds a lost collie, and in another sitcom in 1995 as the mother of a restaurant manager.
Later Roles and Contributions
Her last TV appearance came in 2021 as the voice of Alpha Control in an episode of a streaming service’s remake of Lost in Space. In the movie version featuring well-known actors (1998), she had a holographic 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 organization’s launches and other events. In 2013 her work as a unpaid spokesperson 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 wed John Maloney, a physician and former Navy doctor. In addition to Anne, they had another daughter, June. That marriage ended in separation, as did her subsequent marriage, to John Lindsay, an architect.
She is survived by her children and four grandchildren.
