Launching her career in films, June Lockhart, who passed on aged 100, achieved her greatest success after shifting predominantly to television. Having been offered few chances to excel in films from her first appearance as a youngster in 1938 until 1947, she thrived on TV in numerous beloved series, especially in Lassie.
Her Memorable Role in Lassie
Taking over from a previous star in 1958, Lockhart remained in the series until 1964. She played Ruth Martin, married to farmer Paul Martin and the foster mother of young Timmy Martin, whose dog was the titular hero of the series.
Even with playing a housewife, Lockhart skillfully avoided being overshadowed by the brilliant animal star. She characterized the program as “a fairy tale about people on a rural property in which the dog resolves all the issues in 22 minutes, in time for the last commercial”. After she left the show, Lockhart remarked: “In six sexless years of playing a country wife and parent, I was hardly ever permitted to kiss my co-star on the cheek.”
Journey into Lost in Space
Lockhart went directly into a second successful series, Lost in Space (1965-68), a partly comedic science fiction series targeted mostly at young audiences and inspired by The Swiss Family Robinson. Lockhart and another actor portrayed Maureen and John Robinson, two scientists exploring alien planets. Lockhart had to spend most of her time skillfully trying to survive special effects. As the show continued, the narrative became increasingly less about this space clan and more about the boy and his friendship with a mechanical being, and the cowardly antagonist Dr Zachary Smith.
Early Career and Family Influence
Lockhart’s feature film debut, 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 real-life parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canada-native Gene were both actors in dozens of movies, as well as on theater, it was nearly inevitable that June, who was born in New York, would join the entertainment industry.
Her first stage appearance, at the age of six, came in a non-singing role in an opera at the Metropolitan Opera in New York (1931).
Transition to Hollywood and Movie Roles
When her father was offered a deal by a motion picture studio, after his acclaim on Broadway, she relocated with her family to Hollywood, where Gene made around 300 films. After going to school in Beverly Hills, June began her career 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 last one, she is charming as a New Yorker at a family party, whose dance card 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 sequels to the extremely successful Lassie Come Home (1943), in which a young star had played the female character who assists the canine to escape to the family. In the later film, Lockhart played the now grown-up character.
The affectionate way in which she interacted with both Lassie and her offspring, Laddie, hero of a World War II adventure in Nazi-occupied Norway, was in the consideration of the producers when it came to casting the Lassie TV series 13 years later.
TV and Theater Career
Although she was given leading roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her film career was getting her nowhere and that television would be the answer. Before going in a different direction, she received acclaim on Broadway in For Love or Money (1947), a humorous play for which she won a Tony award as best newcomer.
A further substantial run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a physician and mother figure. She also appeared frequently in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy schedule continued for the following five decades, with a regular role in General Hospital between 1984 and 1998. Among her many guest appearances were as herself 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 Roles and Achievements
Her final TV credit came in 2021 as the narration of Alpha Control in an episode of a streaming service’s remake of Lost in Space. In the big screen version starring famous 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 later astronauts, and often attended the organization’s launches and other events. In 2013 her work as a unpaid representative brought her its Exceptional Public Achievement Medal.
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 earlier self.
Private Information
In 1951 she wed John Maloney, a physician and former Navy doctor. In addition to Anne, they had another daughter, June. That union ended in separation, as did her second marriage, to John Lindsay, an architect.
She is survived by her children and four grandkids.
