June Lockhart, who passed away at the remarkable age of 100, began her professional journey in films, but gained recognition after transitioning almost exclusively to TV. Having been offered few chances to shine in films from her debut as a youngster in 1938 until 1947, she excelled on TV in many beloved series, most notably in Lassie.
Her Iconic Role in Lassie
Stepping in from a previous star in 1958, Lockhart remained in the show until 1964. She played Ruth Martin, married to farmer Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose collie was the eponymous hero of the series.
In her role as a housewife, Lockhart somehow succeeded to avoid being completely upstaged by the intelligent canine. She characterized the program as “a fairy tale about families on a rural property in which the dog solves all the problems 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 parent, I was hardly ever allowed to kiss my co-star on the cheek.”
Adventure into Lost in Space
Lockhart went straight into a second successful series, Lost in Space (1965-68), a semi-spoof science fiction series aimed primarily at young audiences and based by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two scientists exploring alien planets. Lockhart had to spend the majority of her time deftly trying to navigate special effects. As the series continued, the narrative became increasingly less about this interstellar family and increasingly about the young son and his bond with a robot, and the timid villain Dr Zachary Smith.
Early Career and Family Influence
Lockhart’s feature film 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 dozens of movies, as well as on theater, it was nearly certain that June, who was born in New York, would join the entertainment industry.
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 parent was given a contract by a film studio, after his success on Broadway, she relocated with her family to Hollywood, where Gene made around 300 films. After attending school in Beverly Hills, June started her career in films, 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 latter, she is delightful as a New Yorker at a family party, whose schedule is filled spitefully to stop 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 hugely successful Lassie Come Home (1943), in which another actress had played the girl who assists the dog to return to the family. In the subsequent film, Lockhart played the now adult version.
The loving way in which she handled both Lassie and her son, Laddie, hero of a wartime story in enemy-held Norway, was in the minds of the producers when it came to selecting the Lassie TV series 13 years later.
Shift to Television and Stage Achievement
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 embarking in a new direction, she received acclaim on Broadway in For Love or Money (1947), a humorous play for which she won a Tony award as best newcomer.
A further substantial run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a physician and maternal character. She also featured regularly in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy schedule 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 talkshow, where the presenter finds a stray collie, and in another sitcom in 1995 as the mother of a restaurant manager.
Later Roles and Contributions
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 big screen version starring famous actors (1998), she had a holographic cameo as a school principal. She took pleasure in learning how much of an inspiration the original 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 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 earlier 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 marriage ended in divorce, as did her second marriage, to John Lindsay, an designer.
She is remembered by her daughters and four grandchildren.
