June Lockhart, who died at the age of 100, started her professional journey in movies, but achieved recognition after moving almost exclusively to TV. Having been given few chances to shine in films from her debut as a youngster in 1938 until 1947, she excelled on TV in many popular series, most notably in Lassie.
Portraying Ruth Martin on Lassie
Taking over from a previous star in 1958, Lockhart continued in the series until 1964. Her role was Ruth Martin, wed to agriculturalist Paul Martin and the foster mother of young Timmy Martin, whose dog was the eponymous hero of the series.
Even with playing a housewife, Lockhart skillfully avoided being outshone by the smart dog. She described the program as “a fantasy about families on a rural property in which the canine resolves all the issues in 22 minutes, in time for the last advertisement”. After she left the show, Lockhart remarked: “In six sexless years of playing a country wife and mother, I was hardly ever permitted to peck my co-star on the face.”
Featuring in Lost in Space
Lockhart went straight into another successful series, Lost in Space (1965-68), a partly comedic sci-fi series aimed primarily at children and inspired by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two researchers exploring distant planets. Lockhart had to spend the majority of her time deftly trying to survive visual effects. As the series progressed, the narrative became increasingly less about this space family and increasingly about the boy and his bond with a mechanical being, and the cowardly antagonist Dr Zachary Smith.
Early Career and Family Background
Lockhart’s feature film first role, at the young 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 real-life parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canadian-born Gene were both actors in many of movies, as well as on theater, it was almost inevitable that June, who was born in New York, would join the entertainment industry.
Her first theatrical performance, at the tender age of six, came in a non-singing role in an musical production at the Metropolitan Opera in New York (1931).
Cinema Work
When her father was given a contract by a motion picture studio, after his success 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 career 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 last one, she is charming as a New Yorker at a household party, whose schedule is filled spitefully to stop Lockhart interacting with her sibling.
More significantly, although she did not know it at the time, was Son of Lassie (1945). It was one of several sequels to the extremely successful Lassie Come Home (1943), in which a young star had played the female character who helps the dog to return to the family. In the subsequent film, Lockhart played the now adult character.
The affectionate way in which she interacted with both Lassie and her offspring, Laddie, hero of a World War II adventure in Nazi-occupied Norway, was in the consideration of the producers when it came to selecting the Lassie TV series 13 years later.
Television and Theater 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 won 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 significant run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a doctor and mother figure. She also appeared regularly in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy workload continued for the following five decades, with a recurring 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 restaurant manager.
Later Career and Legacy
Her last TV appearance 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 starring famous actors (1998), she had a holographic 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 agency’s launches and other events. In 2013 her work as a unpaid representative 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 younger self.
Personal Details
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 separation, as did her second marriage, to John Lindsay, an designer.
She is survived by her daughters and four grandchildren.
