Starting her career in films, June Lockhart, who died aged 100, found her greatest success after shifting largely to television. Having been given limited chances to shine in films from her debut as a youngster in 1938 until 1947, she thrived on TV in numerous beloved series, especially in Lassie.
Her Memorable Role in Lassie
Taking over from a previous star in 1958, Lockhart continued in the series until 1964. She played Ruth Martin, wed to farmer Paul Martin and the adoptive mother of young Timmy Martin, whose collie was the titular hero of the series.
Despite playing a mother figure, Lockhart adeptly avoided being overshadowed by the smart animal star. She described the program as “a fairy tale about families on a farm in which the dog resolves all the issues in 22 minutes, in time for the last commercial”. After she departed the show, Lockhart commented: “In six sexless years of playing a rural wife and parent, I was hardly ever permitted to peck my co-star on the face.”
Adventure into Lost in Space
Lockhart went directly into another successful series, Lost in Space (1965-68), a partly comedic science fiction series aimed mostly at young audiences and inspired by The Swiss Family Robinson. Lockhart and her co-star portrayed Maureen and John Robinson, two scientists investigating alien planets. Lockhart had to spend the majority of her time deftly trying to navigate visual effects. As the show continued, the storyline became less and less about this interstellar family and increasingly about the boy and his bond with a robot, and the cowardly villain Dr Zachary Smith.
Beginnings in Entertainment
Lockhart’s feature film first role, at the young 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 British-born Kathleen and Canadian-born Gene were both actors in many of movies, as well as on theater, it was nearly inevitable that June, who was born in New York, would join show business.
Her first stage performance, at the age of six, came in a non-musical role in an musical production at the Metropolitan Opera in New York (1931).
Move to Hollywood and Film Roles
When her father was given a contract by a film studio, after his acclaim 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 professional life in movies, 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 last one, she is charming as a New Yorker at a family party, whose dance card is filled spitefully to prevent Lockhart dancing with her sibling.
More importantly, although she did not know it at the time, was Son of Lassie (1945). It was one of multiple follow-ups to the extremely successful Lassie Come Home (1943), in which another actress had played the female character who assists the dog to escape to the family. In the subsequent film, Lockhart played the now adult character.
The loving way in which she handled both Lassie and her offspring, Laddie, hero of a wartime adventure in enemy-held Norway, was in the consideration of the producers when it came to selecting the Lassie TV series 13 years later.
Television and Stage Work
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 getting her nowhere and that TV would be the answer. Before embarking in a different direction, she won praise on Broadway in For Love or Money (1947), a comedy for which she won a Tony award as most promising newcomer.
A additional substantial run came with Petticoat Junction (1968-70), set in a country 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 hectic workload persisted 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 comedy series, where the presenter finds a stray collie, and in another sitcom in 1995 as the parent of a dining manager.
Later Roles and Contributions
Her last 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 movie version featuring well-known actors (1998), she had a digital cameo as a school principal. She took joy in learning how much of an inspiration the original series had been to later astronauts, and often attended the organization’s launches and other events. In 2013 her work as a volunteer spokesperson brought her its prestigious award.
Among her limited subsequent feature films was the fantasy, Troll (1986) in which she played 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 doctor. In addition to Anne, they had a second daughter, June. That marriage ended in divorce, as did her subsequent marriage, to John Lindsay, an designer.
She is remembered by her daughters and four grandkids.
