Starting her career in films, June Lockhart, who died aged 100, found her greatest success after switching largely to television. Having been offered limited chances to excel in movies from her debut as a child in 1938 until 1947, she excelled on television in many popular series, especially in Lassie.
Her Memorable Role in Lassie
Stepping in from a previous star in 1958, Lockhart continued in the show until 1964. Her role was Ruth Martin, wed to agriculturalist Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose collie was the eponymous star of the series.
In her role as a homemaker, Lockhart somehow succeeded to avoid being completely overshadowed by the intelligent dog. She described the show as “a fairy tale about people on a farm in which the dog resolves all the problems in 22 minutes, in time for the last advertisement”. After she left the series, Lockhart commented: “In six chaste years of playing a country spouse and parent, I was hardly ever permitted to kiss my co-star on the cheek.”
Starring in Lost in Space
Lockhart went straight into another hit, Lost in Space (1965-68), a semi-spoof science fiction series targeted primarily at young audiences and inspired by The Swiss Family Robinson. Lockhart and her co-star portrayed Maureen and John Robinson, two scientists exploring alien planets. Lockhart had to spend most of her time skillfully trying to survive special effects. As the show continued, the narrative became increasingly less about this interstellar family and increasingly about the boy and his bond with a robot, and the timid villain Dr Zachary Smith.
Start in Entertainment
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 real-life parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canada-native Gene were both performers in many of films, as well as on stage, it was almost inevitable that June, who was born in New York, would join show business.
Her first theatrical performance, at the age of six, came in a non-musical role in an opera at the Metropolitan Opera in New York (1931).
Transition to Hollywood and Film Roles
When her parent was offered a deal by a motion picture 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 began her career in films, 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 latter, she is charming as a New Yorker at a household party, whose dance card is arranged maliciously 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 follow-ups to the hugely successful Lassie Come Home (1943), in which another actress had played the girl who assists the canine to return to the family. In the subsequent film, Lockhart played the now grown-up character.
The affectionate way in which she handled 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 Stage Career
Although she was offered major 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 humorous play for which she won a Tony award as most promising newcomer.
A further substantial run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a physician and mother figure. She also appeared frequently in TV westerns 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 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 presenter finds a lost collie, and in another sitcom in 1995 as the mother of a restaurant manager.
Later Career and Legacy
Her last TV credit came in 2021 as the voice of Alpha Control in an episode of a digital platform’s remake of Lost in Space. In the movie version featuring well-known actors (1998), she had a digital cameo as a school principal. She took pleasure in learning how much of an inspiration the first series had been to future astronauts, and often participated in the agency’s launches and other events. In 2013 her work as a volunteer 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.
Personal Life and Family
In 1951 she wed John Maloney, a physician and former Navy doctor. 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 remembered by her children and four grandkids.
