June Lockhart, who passed away at the remarkable age of 100, began her career in movies, but gained recognition after transitioning almost entirely to TV. Having been offered limited chances to shine in films from her first appearance as a youngster in 1938 until 1947, she thrived on television in numerous popular series, especially 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, married to farmer Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose dog was the eponymous star of the series.
In her part as a housewife, Lockhart somehow managed to avoid being totally upstaged by the intelligent canine. She characterized the program as “a fantasy about people on a farm in which the dog solves all the problems in 22 minutes, in time for the last advertisement”. After she left the show, Lockhart remarked: “In six chaste years of playing a country wife and parent, I was rarely permitted to kiss my on-screen husband on the cheek.”
Featuring in Lost in Space
Lockhart went directly into another hit, Lost in Space (1965-68), a semi-spoof science fiction series aimed primarily at children and based by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two scientists investigating distant planets. Lockhart had to spend most of her time deftly trying to navigate special effects. As the series progressed, the narrative became increasingly less about this interstellar clan and increasingly about the young son and his friendship with a mechanical being, and the cowardly villain Dr Zachary Smith.
Early Career and Family Influence
Lockhart’s movie first role, 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 Canadian-born Gene were both actors in dozens 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 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 moved with her parents to Hollywood, where Gene made around 300 films. After going to school in Beverly Hills, June began her career in films, 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 latter, she is delightful as a New Yorker at a family party, whose schedule is arranged maliciously to stop 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 female character who helps the canine to return to the owners. In the later film, Lockhart played the now grown-up character.
The loving way in which she handled both Lassie and her offspring, Laddie, hero of a wartime story in enemy-held Norway, was in the minds of the producers when it came to selecting the Lassie TV series 13 years later.
TV 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 getting her nowhere and that television would be the answer. Before embarking in a different 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 doctor 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 busy workload persisted for the following 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 talkshow, where the host finds a stray collie, and in another sitcom in 1995 as the mother of a restaurant manager.
Later Roles and Achievements
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 featuring well-known 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 attended the agency’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 witch, with her own daughter, Anne Lockhart, playing her earlier self.
Personal Details
In 1951 she married John Maloney, a doctor and former Navy medical officer. In addition to Anne, they had another daughter, June. That marriage ended in separation, as did her second marriage, to John Lindsay, an architect.
She is survived by her daughters and four grandkids.
