June Lockhart, who died at the age of 100, began her career in films, but achieved recognition after moving almost exclusively to television. Having been given few opportunities to excel in films from her first appearance as a youngster in 1938 until 1947, she thrived on TV in numerous beloved series, especially in Lassie.
Her Iconic Role in Lassie
Taking over from another actress in 1958, Lockhart continued in the show until 1964. She played Ruth Martin, married to farmer Paul Martin and the foster mother of seven-year-old Timmy Martin, whose collie was the titular star of the series.
In her part as a housewife, Lockhart somehow managed to avoid being totally upstaged by the intelligent dog. She described the program 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 commented: “In six sexless years of playing a rural spouse and mother, I was rarely allowed to kiss my co-star on the cheek.”
Journey into Lost in Space
Lockhart went straight into another hit, Lost in Space (1965-68), a semi-spoof science fiction series aimed mostly at young audiences and inspired by The Swiss Family Robinson. Lockhart and another actor portrayed Maureen and John Robinson, two scientists investigating alien planets. Lockhart had to spend the majority of her time deftly trying to navigate visual effects. As the show continued, the storyline became less and less about this space family and more about the young son and his bond with a mechanical being, and the timid antagonist Dr Zachary Smith.
Start in Entertainment
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 parents, Bob and Mrs Cratchit, were her real-life parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canada-native Gene were both actors in dozens of films, as well as on theater, it was almost certain that June, who was born in New York, would join show business.
Her first stage appearance, at the age of six, came in a non-singing role in an musical production at the Metropolitan Opera in New York (1931).
Move to Hollywood and Movie Roles
When her father was offered a contract by a film studio, after his success on Broadway, she moved with her family to Hollywood, where Gene made approximately 300 films. After attending school in Beverly Hills, June began 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 delightful as a New Yorker at a household party, whose schedule is filled spitefully 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 several sequels to the hugely successful Lassie Come Home (1943), in which a young star had played the girl who helps the dog to return to the family. In the subsequent film, Lockhart played the now adult version.
The loving way in which she interacted with both Lassie and her offspring, Laddie, hero of a wartime adventure in Nazi-occupied Norway, was in the consideration of the creators when it came to selecting the Lassie TV series 13 years later.
Shift to Television and Broadway Achievement
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 stagnating and that TV would be the solution. Before going 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 country hotel, where Lockhart is a physician and maternal character. She also appeared regularly in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic workload 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 comedy series, where the host finds a stray collie, and in another sitcom in 1995 as the parent of a restaurant manager.
Later Roles and Achievements
Her final TV appearance came in 2021 as the narration of Alpha Control in an episode of a streaming service’s remake of Lost in Space. In the big screen version featuring well-known actors (1998), she had a digital cameo as a school principal. She took joy in learning how much of an influence the first series had been to future astronauts, and often attended the organization’s launches and other events. In 2013 her work as a unpaid representative brought her its Exceptional Public Achievement Medal.
Among her few 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 Information
In 1951 she married John Maloney, a doctor and former Navy medical officer. In addition to Anne, they had another daughter, June. That union ended in divorce, as did her second marriage, to John Lindsay, an architect.
She is survived by her children and four grandkids.
