June Lockhart: A Lifetime of TV Success from Lassie to Lost in Space
Starting her career in films, June Lockhart, who died aged 100, found her greatest success after switching predominantly to television. Having been given limited opportunities to shine in films from her first appearance as a youngster in 1938 until 1947, she thrived on television in numerous popular series, especially in Lassie.
Her Memorable Role in Lassie
Stepping in from another actress in 1958, Lockhart continued in the series until 1964. She played Ruth Martin, wed to agriculturalist Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose dog was the eponymous star of the series.
In her role as a housewife, Lockhart somehow succeeded to avoid being completely upstaged by the clever canine. She described the program as “a fantasy about people on a farm in which the canine solves all the problems in 22 minutes, in time for the last advertisement”. After she left the series, Lockhart remarked: “In six chaste years of playing a rural wife and parent, I was hardly ever allowed to kiss my on-screen husband on the cheek.”
Starring in Lost in Space
Lockhart went straight into a second successful series, 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 portrayed Maureen and John Robinson, two researchers investigating alien planets. Lockhart had to spend the majority of her time deftly trying to navigate special effects. As the series progressed, the storyline became increasingly less about this space clan and more about the boy and his bond with a robot, and the timid antagonist Dr Zachary Smith.
Beginnings in Show Business
Lockhart’s movie debut, at the 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 actual parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canada-native Gene were both performers in many of films, as well as on theater, it was nearly certain that June, who was born in New York, would join the entertainment industry.
Her first stage appearance, at the tender 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 father 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 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 latter, she is charming as a New Yorker at a family party, whose schedule is filled maliciously to stop Lockhart interacting with her brother.
More significantly, although she did not know 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 a young star 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 handled both Lassie and her offspring, Laddie, hero of a World War II story in enemy-held Norway, was in the minds of the producers when it came to casting the Lassie TV series 13 years later.
Television and Stage Career
Although she was given leading roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her movie career was stagnating and that TV would be the solution. Before embarking in a new direction, she received praise on Broadway in For Love or Money (1947), a comedy for which she won a Tony award as best 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 featured frequently in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic schedule 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 mother of a restaurant manager.
Final Career and Impact
Her last TV appearance 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 movie version starring famous actors (1998), she had a digital cameo as a school principal. She took joy in learning how much of an inspiration the original series had been to future astronauts, and often participated in the agency’s launches and other events. In 2013 her work as a unpaid representative brought her its Exceptional Public Achievement Medal.
Among her limited subsequent feature films was the fantasy, Troll (1986) in which she portrayed a witch, with her own daughter, Anne Lockhart, playing her younger 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 marriage ended in divorce, as did her subsequent marriage, to John Lindsay, an designer.
She is survived by her children and four grandchildren.
