June Lockhart, who passed away at the age of 100, started her career in films, but gained fame after moving almost exclusively to TV. Having been offered limited opportunities to shine in films from her debut as a youngster in 1938 until 1947, she thrived on television in many beloved series, especially in Lassie.
Her Memorable Role in Lassie
Taking over from a previous star in 1958, Lockhart remained in the series until 1964. She played Ruth Martin, married to farmer Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose dog was the eponymous hero of the series.
In her part as a housewife, Lockhart somehow succeeded to avoid being completely upstaged by the intelligent canine. She described the program as “a fantasy about families on a farm in which the dog solves all the issues in 22 minutes, in time for the last commercial”. After she left the series, Lockhart commented: “In six chaste years of playing a country wife and mother, I was rarely allowed to peck my on-screen husband on the cheek.”
Starring in Lost in Space
Lockhart went directly into a second successful series, Lost in Space (1965-68), a semi-spoof sci-fi series aimed primarily at young audiences and inspired by The Swiss Family Robinson. Lockhart and another actor portrayed Maureen and John Robinson, two researchers investigating distant planets. Lockhart had to spend the majority of her time deftly trying to survive special effects. As the show continued, the storyline became less and less about this space family and more about the boy and his bond with a robot, and the timid antagonist Dr Zachary Smith.
Early Career and Family Background
Lockhart’s movie debut, at the 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 many of movies, as well as on theater, it was almost certain that June, who was born in New York, would enter the entertainment industry.
Her first stage performance, at the age of six, came in a non-singing role in an opera at the Metropolitan Opera in New York (1931).
Cinema Career
When her father was offered a contract by a motion picture studio, after his success on Broadway, she moved with her parents to Hollywood, where Gene made around 300 films. After attending school in Beverly Hills, June started her career in movies, mainly in minor roles in acclaimed 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 schedule is filled maliciously to prevent Lockhart interacting with her brother.
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 extremely 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 version.
The loving way in which she interacted with both Lassie and her son, Laddie, hero of a World War II story in Nazi-occupied Norway, was in the consideration of the creators when it came to selecting the Lassie TV series 13 years later.
TV and Stage Career
Although she was given major roles in two thrillers, 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 solution. Before embarking in a new 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 significant run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a doctor and maternal character. She also featured regularly in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic schedule persisted for the next five decades, with a regular role in General Hospital between 1984 and 1998. Among her many one-off 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 Career and Impact
Her final 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 starring well-known actors (1998), she had a holographic cameo as a school principal. She took pleasure in learning how much of an influence the original series had been to later astronauts, and often participated in the agency’s launches and other events. In 2013 her work as a unpaid representative brought her its prestigious award.
Among her limited subsequent feature films was the fantasy, Troll (1986) in which she portrayed a sorceress, with her own daughter, Anne Lockhart, playing her younger self.
Private Details
In 1951 she wed John Maloney, a physician and former Navy medical officer. 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.
