Launching her career in cinema, June Lockhart, who passed on aged 100, achieved her greatest success after switching predominantly to the small screen. Having been given few chances to shine in films from her debut as a child in 1938 until 1947, she excelled on television in many beloved series, most notably in Lassie.
Her Memorable Role in Lassie
Taking over from a previous star in 1958, Lockhart remained in the show until 1964. She played Ruth Martin, wed to farmer Paul Martin and the foster mother of young Timmy Martin, whose dog was the eponymous star of the series.
In her part as a housewife, Lockhart somehow succeeded to avoid being totally overshadowed by the clever dog. She characterized the program as “a fantasy about people on a farm in which the dog resolves all the issues in 22 minutes, in time for the last commercial”. After she left the series, Lockhart remarked: “In six sexless years of playing a country spouse and mother, I was hardly ever allowed to peck my on-screen husband on the cheek.”
Journey into Lost in Space
Lockhart went directly into a second hit, Lost in Space (1965-68), a partly comedic sci-fi series targeted mostly at young audiences and based by The Swiss Family Robinson. Lockhart and her co-star played Maureen and John Robinson, two scientists exploring alien planets. Lockhart had to spend most of her time skillfully trying to navigate special effects. As the series continued, the storyline became less and less about this space clan and increasingly about the boy and his bond with a robot, and the timid villain Dr Zachary Smith.
Early Career and Family Background
Lockhart’s movie debut, at the 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 British-born Kathleen and Canada-native Gene were both actors in many of films, as well as on stage, it was nearly certain that June, who was born in New York, would enter the entertainment industry.
Her first theatrical appearance, at the age of six, came in a non-singing role in an musical production at the Metropolitan Opera in New York (1931).
Cinema Work
When her father was offered a contract by a motion picture studio, after his acclaim on Broadway, she moved with her family 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 family party, whose dance card is arranged maliciously to stop Lockhart interacting with her brother.
More significantly, although she did not realize it at the time, was Son of Lassie (1945). It was one of multiple sequels to the hugely successful Lassie Come Home (1943), in which another actress had played the female character who assists the dog to escape to the owners. In the subsequent film, Lockhart played the now adult character.
The loving way in which she handled both Lassie and her offspring, Laddie, hero of a wartime 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 suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her movie career was stagnating and that television would be the answer. Before going in a new direction, she won acclaim on Broadway in For Love or Money (1947), a comedy for which she won a Tony award as most promising newcomer.
A additional significant run came with Petticoat Junction (1968-70), set in a country 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 continued 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 talkshow, where the host finds a stray collie, and in another sitcom in 1995 as the parent of a dining manager.
Later Career and Impact
Her final TV appearance came in 2021 as the narration 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 digital cameo as a school principal. She took joy in learning how much of an inspiration the first series had been to future astronauts, and often attended the organization’s launches and other events. In 2013 her work as a unpaid representative brought her its prestigious award.
Among her limited subsequent feature films was the fantasy, Troll (1986) in which she portrayed a sorceress, with her own daughter, Anne Lockhart, playing her earlier self.
Personal Life and Family
In 1951 she married 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 designer.
She is survived by her children and four grandkids.
