June Lockhart, who passed away at the remarkable age of 100, began her professional journey in movies, but achieved recognition after moving almost entirely to television. Having been given few opportunities to shine in films from her first appearance as a youngster in 1938 until 1947, she thrived on television in numerous beloved series, most notably in Lassie.
Portraying Ruth Martin on 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 young Timmy Martin, whose collie was the titular star of the series.
In her part as a housewife, Lockhart somehow managed to avoid being completely upstaged by the intelligent canine. She described the show as “a fairy tale about people on a rural property in which the dog solves all the issues in 22 minutes, in time for the last advertisement”. After she left the series, Lockhart remarked: “In six chaste years of playing a country spouse and mother, I was rarely permitted to peck my on-screen husband on the face.”
Starring in Lost in Space
Lockhart went directly into another successful series, Lost in Space (1965-68), a partly comedic science fiction series targeted primarily at children and inspired by The Swiss Family Robinson. Lockhart and another actor portrayed Maureen and John Robinson, two researchers investigating alien planets. Lockhart had to spend most of her time skillfully trying to survive visual effects. As the series progressed, the storyline became less and less about this space clan and increasingly about the boy and his bond with a mechanical being, and the cowardly villain Dr Zachary Smith.
Start in Show Business
Lockhart’s feature film debut, 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 British-born Kathleen and Canada-native Gene were both actors 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 performance, at the age of six, came in a non-musical role in an opera at the Metropolitan Opera in New York (1931).
Hollywood Career
When her father was given a contract by a motion picture studio, after his acclaim on Broadway, she moved with her family to Hollywood, where Gene made around 300 films. After attending school in Beverly Hills, June started her professional life 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 delightful as a New Yorker at a household party, whose dance card is filled spitefully to prevent Lockhart dancing with her brother.
More importantly, although she did not realize it at the time, was Son of Lassie (1945). It was one of multiple sequels to the extremely successful Lassie Come Home (1943), in which a young star had played the girl who assists the canine to escape to the owners. In the later film, Lockhart played the now adult character.
The loving way in which she handled both Lassie and her son, Laddie, protagonist of a wartime adventure in Nazi-occupied Norway, was in the minds of the creators when it came to selecting the Lassie TV series 13 years later.
Television and Stage Career
Although she was given major roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her movie career was getting her nowhere and that TV would be the answer. 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 best newcomer.
A further significant 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 cowboy shows 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 regular role in General Hospital between 1984 and 1998. Among her many one-off 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 parent of a dining manager.
Later Career and Legacy
Her last TV credit came in 2021 as the narration of Alpha Control in an episode of a streaming service’s new version of Lost in Space. In the big screen version featuring famous 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 attended the organization’s launches and other events. In 2013 her work as a volunteer spokesperson brought her its prestigious award.
Among her limited 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 Life and Family
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 children and four grandchildren.
