June Lockhart, who passed away at the age of 100, started her career in movies, but achieved fame after transitioning almost exclusively to television. Having been given limited chances to shine in movies from her first appearance as a child in 1938 until 1947, she thrived on television in many beloved series, most notably in Lassie.
Her Memorable Role in Lassie
Taking over from a previous star in 1958, Lockhart continued in the series until 1964. She played Ruth Martin, wed to farmer Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose collie was the eponymous star of the series.
Even with playing a housewife, Lockhart adeptly avoided being overshadowed by the brilliant dog. She described the show as “a fairy tale about people on a farm in which the canine solves all the problems in 22 minutes, in time for the last advertisement”. After she departed the show, Lockhart commented: “In six sexless years of playing a country spouse and mother, I was rarely permitted to peck my co-star on the cheek.”
Journey into Lost in Space
Lockhart went straight into a second successful series, Lost in Space (1965-68), a semi-spoof sci-fi series targeted primarily 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 deftly trying to navigate special effects. As the series progressed, the narrative became increasingly less about this interstellar clan and increasingly about the boy and his friendship with a robot, and the timid villain 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 mother and father, 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 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 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 contract 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 movies, mainly in minor roles in prestigious 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 interacting with her sibling.
More significantly, 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 owners. In the subsequent film, Lockhart played the now grown-up character.
The loving way in which she handled both Lassie and her son, Laddie, protagonist of a wartime story in Nazi-occupied Norway, was in the minds of the creators when it came to selecting the Lassie TV series 13 years later.
Television and Stage Career
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 going in a different direction, she won acclaim on Broadway in For Love or Money (1947), a humorous play 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 doctor and mother figure. She also appeared regularly in TV cowboy shows 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 host finds a lost collie, and in another sitcom in 1995 as the parent of a dining manager.
Final Career and Impact
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 holographic cameo as a school principal. She took joy in learning how much of an inspiration the original series had been to later astronauts, and often attended the agency’s launches and other events. In 2013 her work as a volunteer representative brought her its prestigious award.
Among her limited later feature films was the fantasy, Troll (1986) in which she portrayed a witch, 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 medical officer. In addition to Anne, they had another daughter, June. That marriage ended in separation, as did her second marriage, to John Lindsay, an architect.
She is survived by her children and four grandchildren.
