June Lockhart, who passed away at the remarkable age of 100, began her career in films, but gained fame after moving almost entirely to television. Having been offered limited chances to excel in movies from her first appearance as a youngster in 1938 until 1947, she thrived on television in numerous popular series, most notably in Lassie.
Portraying Ruth Martin on Lassie
Taking over from a previous star in 1958, Lockhart remained in the series until 1964. She played 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.
Despite playing a housewife, Lockhart skillfully avoided being overshadowed by the smart dog. She characterized the program as “a fairy tale about families on a rural property in which the canine resolves all the problems in 22 minutes, in time for the last commercial”. After she left the series, Lockhart commented: “In six sexless years of playing a country spouse and parent, I was hardly ever permitted to kiss my on-screen husband on the face.”
Starring in Lost in Space
Lockhart went straight into a second successful series, Lost in Space (1965-68), a partly comedic science fiction series aimed primarily at children and based by The Swiss Family Robinson. Lockhart and another actor portrayed Maureen and John Robinson, two researchers exploring distant planets. Lockhart had to spend most of her time deftly trying to survive special effects. As the show progressed, the storyline became less and less about this interstellar family and increasingly about the young son and his friendship with a robot, and the cowardly antagonist Dr Zachary Smith.
Initial Career and Family Influence
Lockhart’s movie debut, at the age of 13, had come as Belinda Cratchit in A Christmas Carol (1938). In the roles of her parents, Bob and Mrs Cratchit, were her actual parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canadian-born Gene were both performers in dozens 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 theatrical performance, at the age of six, came in a non-musical role in an musical production at the Metropolitan Opera in New York (1931).
Cinema Career
When her father was given a contract by a film studio, after his success on Broadway, she moved with her parents to Hollywood, where Gene made around 300 films. After going to school in Beverly Hills, June began her professional life in movies, mainly 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 schedule is arranged maliciously to prevent Lockhart interacting with her brother.
More significantly, although she did not know 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 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 son, Laddie, hero of a World War II 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 Theater Work
Although she was given major roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her movie career was stagnating and that television 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 substantial run came with Petticoat Junction (1968-70), set in a rural 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 busy schedule persisted for the next five decades, with a recurring role in General Hospital between 1984 and 1998. Among her many one-off appearances were as herself in a 1988 episode of a comedy series, where the host finds a stray collie, and in another sitcom in 1995 as the parent of a restaurant manager.
Final Roles and Achievements
Her last TV appearance came in 2021 as the voice of Alpha Control in an episode of a streaming service’s remake of Lost in Space. In the movie version featuring famous 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 future astronauts, and often participated in 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 portrayed a sorceress, 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 union ended in divorce, as did her subsequent marriage, to John Lindsay, an designer.
She is remembered by her daughters and four grandchildren.
