June Lockhart, who passed away at the remarkable age of 100, started her career in films, but achieved fame after moving almost exclusively to television. Having been offered few chances to shine in films from her first appearance as a youngster in 1938 until 1947, she excelled on television in numerous popular series, especially in Lassie.
Her Iconic Role in Lassie
Taking over from another actress in 1958, Lockhart remained in the series until 1964. She played Ruth Martin, married to agriculturalist Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose dog was the titular star of the series.
In her role as a housewife, Lockhart somehow managed to avoid being completely overshadowed by the intelligent canine. She characterized the show as “a fantasy about people on a rural property in which the dog resolves all the problems in 22 minutes, in time for the last commercial”. After she left the show, Lockhart commented: “In six sexless years of playing a country spouse and mother, I was hardly ever allowed to kiss my co-star on the face.”
Featuring in Lost in Space
Lockhart went directly into a second hit, Lost in Space (1965-68), a semi-spoof sci-fi series targeted primarily at young audiences and based by The Swiss Family Robinson. Lockhart and her co-star portrayed Maureen and John Robinson, two scientists investigating distant planets. Lockhart had to spend most of her time skillfully trying to navigate visual effects. As the show progressed, the storyline became increasingly less about this interstellar family and increasingly about the young son and his bond with a mechanical being, and the cowardly antagonist Dr Zachary Smith.
Initial Career and Family Background
Lockhart’s feature film first role, 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 actual parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canada-native Gene were both performers in many of movies, as well as on stage, it was almost inevitable 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 musical production at the Metropolitan Opera in New York (1931).
Hollywood Career
When her parent was given a contract 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 professional life in movies, mostly in minor roles in prestigious pictures such as Sergeant York (1941), The White Cliffs of Dover (1942) and Meet Me in St Louis (1944). In the last one, she is delightful as a New Yorker at a family party, whose dance card is filled maliciously to prevent Lockhart dancing with her sibling.
More significantly, although she did not know 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 later film, Lockhart played the now grown-up character.
The loving way in which she handled both Lassie and her offspring, Laddie, protagonist of a wartime story in Nazi-occupied Norway, was in the consideration of the creators when it came to casting the Lassie TV series 13 years later.
Transition to Television and Broadway Success
Although she was given major roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her film career was getting her nowhere and that TV would be the answer. 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 maternal character. She also appeared frequently in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic workload continued for the next five decades, with a recurring role in General Hospital between 1984 and 1998. Among her many guest appearances were as herself in a 1988 episode of a talkshow, where the presenter finds a lost collie, and in another sitcom in 1995 as the mother of a dining manager.
Later Roles and Achievements
Her last 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 movie version starring well-known actors (1998), she had a digital 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 participated in 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 portrayed a witch, with her own daughter, Anne Lockhart, playing her earlier self.
Private Information
In 1951 she married John Maloney, a doctor and former Navy medical officer. In addition to Anne, they had another 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.
