Starting her career in films, June Lockhart, who passed on aged 100, found her biggest success after shifting predominantly to television. Having been given limited chances to shine in movies from her debut as a youngster in 1938 until 1947, she excelled on television in many beloved series, most notably in Lassie.
Her Iconic Role in Lassie
Taking over from another actress in 1958, Lockhart remained in the show until 1964. Her role was Ruth Martin, married to farmer Paul Martin and the foster mother of young Timmy Martin, whose collie was the titular star of the series.
Despite playing a housewife, Lockhart adeptly avoided being outshone by the smart animal star. She characterized the program as “a fairy tale about people on a farm in which the canine resolves all the issues in 22 minutes, in time for the last advertisement”. After she departed the show, Lockhart commented: “In six chaste years of playing a rural spouse and mother, I was hardly ever permitted to kiss my on-screen husband on the face.”
Journey into Lost in Space
Lockhart went straight into a second hit, Lost in Space (1965-68), a partly comedic sci-fi series targeted primarily at young audiences and inspired by The Swiss Family Robinson. Lockhart and another actor portrayed Maureen and John Robinson, two researchers investigating distant planets. Lockhart had to spend most of her time deftly trying to survive special effects. As the show progressed, the narrative became increasingly less about this interstellar clan and increasingly about the young son and his friendship with a robot, and the cowardly villain Dr Zachary Smith.
Start in Entertainment
Lockhart’s feature film debut, at the age of 13, had come as Belinda Cratchit in A Christmas Carol (1938). In the roles of her parents, Bob and Mrs Cratchit, were her actual parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canada-native Gene were both performers in dozens of movies, as well as on theater, it was nearly inevitable that June, who was born in New York, would enter the entertainment industry.
Her first theatrical appearance, at the tender age of six, came in a non-singing role in an opera at the Metropolitan Opera in New York (1931).
Cinema Work
When her father was given a deal by a film studio, after his success on Broadway, she relocated with her family to Hollywood, where Gene made approximately 300 films. After going to school in Beverly Hills, June started her career in movies, mainly 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 charming as a New Yorker at a family party, whose dance card 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 several sequels to the hugely successful Lassie Come Home (1943), in which another actress had played the female character who helps the dog to return to the owners. In the subsequent film, Lockhart played the now grown-up character.
The affectionate way in which she interacted with both Lassie and her offspring, Laddie, hero of a World War II adventure in enemy-held Norway, was in the minds of the creators when it came to casting the Lassie TV series 13 years later.
TV and Theater Work
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 getting her nowhere and that television would be the solution. Before going in a new direction, she received 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 significant run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a physician and mother figure. She also appeared regularly in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic workload continued for the following five decades, with a recurring role in General Hospital between 1984 and 1998. Among her many one-off appearances were as herself in a 1988 episode of a talkshow, where the presenter finds a stray collie, and in another sitcom in 1995 as the parent of a dining manager.
Later Roles and Achievements
Her final TV credit came in 2021 as the voice of Alpha Control in an episode of a streaming service’s new version of Lost in Space. In the movie version starring famous actors (1998), she had a holographic cameo as a school principal. She took pleasure in learning how much of an influence the original series had been to later astronauts, and often attended the agency’s launches and other events. In 2013 her work as a volunteer spokesperson brought her its prestigious award.
Among her few later feature films was the fantasy, Troll (1986) in which she played a witch, with her own daughter, Anne Lockhart, playing her earlier self.
Personal Information
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 separation, as did her subsequent marriage, to John Lindsay, an designer.
She is remembered by her children and four grandkids.
