Launching her career in cinema, June Lockhart, who died aged 100, found her biggest success after switching largely to television. Having been given few opportunities to excel in films from her debut as a youngster in 1938 until 1947, she excelled on television in numerous popular series, especially in Lassie.
Her Memorable Role in Lassie
Taking over from a previous star in 1958, Lockhart remained in the series until 1964. Her role was Ruth Martin, wed to agriculturalist Paul Martin and the adoptive mother of young Timmy Martin, whose dog was the eponymous star of the series.
Despite playing a housewife, Lockhart adeptly avoided being outshone by the smart dog. She characterized the program as “a fantasy about people on a rural property in which the canine resolves all the problems 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 mother, I was hardly ever allowed to peck my on-screen husband on the face.”
Adventure into Lost in Space
Lockhart went directly into a second successful series, Lost in Space (1965-68), a partly comedic 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 scientists investigating alien planets. Lockhart had to spend most of her time deftly trying to navigate special effects. As the series continued, the storyline became less and less about this space clan and more about the young son and his bond with a robot, and the timid villain Dr Zachary Smith.
Beginnings in Entertainment
Lockhart’s movie debut, at the young age of 13, had come as Belinda Cratchit in A Christmas Carol (1938). In the roles of her mother and father, Bob and Mrs Cratchit, were her real-life parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canadian-born Gene were both actors in many of movies, as well as on stage, it was almost 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).
Transition to Hollywood and Film Roles
When her parent was offered a deal by a motion picture studio, after his success on Broadway, she moved with her parents to Hollywood, where Gene made approximately 300 films. After going to school in Beverly Hills, June began her career in movies, mostly 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 latter, she is delightful as a New Yorker at a household party, whose schedule is filled maliciously 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 sequels to the hugely successful Lassie Come Home (1943), in which a young star had played the female character who assists the canine to return to the family. In the later film, Lockhart played the now grown-up version.
The loving way in which she handled both Lassie and her son, Laddie, hero of a wartime adventure in Nazi-occupied Norway, was in the minds of the creators when it came to selecting the Lassie TV series 13 years later.
Shift to Television and Stage Success
Although she was offered leading 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 solution. Before embarking in a new direction, she won praise on Broadway in For Love or Money (1947), a humorous play for which she won a Tony award as most promising newcomer.
A additional substantial run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a doctor and mother figure. She also featured frequently in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy schedule persisted for the next five decades, with a regular role in General Hospital between 1984 and 1998. Among her many one-off appearances were as the actress 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.
Final Roles and Achievements
Her last TV credit came in 2021 as the narration of Alpha Control in an episode of a digital platform’s new version of Lost in Space. In the big screen version featuring well-known actors (1998), she had a holographic cameo as a school principal. She took joy in learning how much of an inspiration the first series had been to later astronauts, and often attended the agency’s launches and other events. In 2013 her work as a unpaid spokesperson brought her its Exceptional Public Achievement Medal.
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 younger self.
Private Details
In 1951 she married John Maloney, a doctor and former Navy medical officer. In addition to Anne, they had a second daughter, June. That union ended in divorce, as did her subsequent marriage, to John Lindsay, an designer.
She is remembered by her daughters and four grandkids.
