Launching her career in films, June Lockhart, who died aged 100, achieved her greatest success after switching predominantly to the small screen. Having been offered limited chances to excel in films from her first appearance as a child in 1938 until 1947, she excelled on television in many popular series, most notably in Lassie.
Her Memorable Role in Lassie
Stepping in 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 young Timmy Martin, whose collie was the eponymous star of the series.
In her part as a housewife, Lockhart somehow succeeded to avoid being completely upstaged by the intelligent canine. She characterized the program as “a fantasy about families on a rural property in which the dog solves all the issues in 22 minutes, in time for the last commercial”. 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 on-screen husband on the face.”
Featuring in Lost in Space
Lockhart went directly into a second hit, Lost in Space (1965-68), a partly comedic science fiction series targeted mostly at children and based by The Swiss Family Robinson. Lockhart and her co-star played Maureen and John Robinson, two researchers investigating alien planets. Lockhart had to spend most of her time skillfully trying to navigate special effects. As the show continued, the narrative became increasingly less about this interstellar clan and more about the boy and his bond with a robot, and the timid antagonist Dr Zachary Smith.
Start in Show Business
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 many of movies, as well as on theater, it was nearly certain that June, who was born in New York, would enter show business.
Her first theatrical appearance, at the tender age of six, came in a non-musical 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 moved with her family to Hollywood, where Gene made around 300 films. After going to school in Beverly Hills, June began her professional life in movies, mostly in small 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 schedule is arranged spitefully to prevent 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 follow-ups to the extremely successful Lassie Come Home (1943), in which another actress had played the girl who assists the dog to escape to the owners. In the subsequent film, Lockhart played the now grown-up version.
The affectionate way in which she interacted with both Lassie and her offspring, Laddie, protagonist of a wartime adventure in Nazi-occupied Norway, was in the minds of the producers when it came to casting the Lassie TV series 13 years later.
Shift to Television and Broadway Achievement
Although she was given leading roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her film career was getting her nowhere and that television would be the solution. Before embarking 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 most promising newcomer.
A further significant 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 westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy workload persisted for the following 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 comedy series, where the presenter finds a lost collie, and in another sitcom in 1995 as the parent of a dining manager.
Final Career and Legacy
Her final TV appearance came in 2021 as the narration of Alpha Control in an episode of a streaming service’s new version of Lost in Space. In the big screen 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 first series had been to future astronauts, and often participated in the agency’s launches and other events. In 2013 her work as a volunteer spokesperson 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.
Private Information
In 1951 she wed John Maloney, a doctor and former Navy doctor. In addition to Anne, they had a second daughter, June. That union ended in separation, as did her subsequent marriage, to John Lindsay, an designer.
She is remembered by her daughters and four grandchildren.
