Starting her career in cinema, June Lockhart, who passed on aged 100, found her biggest success after switching largely to television. Having been given limited opportunities to excel in films from her debut as a child in 1938 until 1947, she thrived on TV in numerous beloved series, especially in Lassie.
Her Memorable Role in Lassie
Stepping in from a previous star in 1958, Lockhart continued in the show until 1964. She played Ruth Martin, wed to farmer Paul Martin and the foster mother of seven-year-old Timmy Martin, whose collie was the titular star of the series.
In her part as a housewife, Lockhart somehow succeeded to avoid being completely overshadowed by the clever dog. She described the show as “a fantasy about people on a farm 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 chaste years of playing a country spouse and parent, I was rarely allowed to peck 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 aimed mostly at children and based by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two researchers exploring alien planets. Lockhart had to spend most of her time deftly trying to survive special effects. As the series continued, the narrative became less and less about this interstellar family and more about the boy and his bond with a mechanical being, and the cowardly antagonist Dr Zachary Smith.
Early Career and Family Background
Lockhart’s feature film first role, at the age of 13, had come as Belinda Cratchit in A Christmas Carol (1938). In the parts of her parents, Bob and Mrs Cratchit, were her real-life parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canada-native Gene were both performers in many of movies, as well as on theater, it was almost inevitable that June, who was born in New York, would join show business.
Her first stage performance, at the tender age of six, came in a non-singing role in an opera at the Metropolitan Opera in New York (1931).
Move to Hollywood and Film Roles
When her father was given a deal by a film studio, after his acclaim on Broadway, she moved with her parents to Hollywood, where Gene made approximately 300 films. After attending school in Beverly Hills, June began 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 charming as a New Yorker at a family party, whose schedule is filled maliciously to prevent Lockhart dancing with her brother.
More significantly, although she did not realize it at the time, was Son of Lassie (1945). It was one of several sequels to the extremely successful Lassie Come Home (1943), in which another actress had played the female character who assists the canine to escape to the family. In the subsequent film, Lockhart played the now adult character.
The affectionate way in which she handled both Lassie and her son, Laddie, hero of a World War II story in Nazi-occupied Norway, was in the consideration of the creators when it came to casting the Lassie TV series 13 years later.
TV and Theater Career
Although she was given major roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her film career was getting her nowhere and that television would be the solution. Before going in a different 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 substantial run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a physician and maternal character. She also featured frequently in TV westerns 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 recurring 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 host finds a stray collie, and in another sitcom in 1995 as the mother of a dining manager.
Final Roles and Achievements
Her final TV appearance came in 2021 as the voice 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 pleasure in learning how much of an inspiration the first series had been to later 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 few subsequent feature films was the fantasy, Troll (1986) in which she played a sorceress, with her own daughter, Anne Lockhart, playing her earlier self.
Personal Details
In 1951 she married John Maloney, a physician 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 survived by her children and four grandkids.
