June Lockhart, who died at the remarkable age of 100, began her professional journey in movies, but gained recognition after moving almost exclusively to television. Having been offered few opportunities to shine in films from her first appearance as a child in 1938 until 1947, she thrived on television in many beloved series, most notably in Lassie.
Portraying Ruth Martin on Lassie
Stepping in 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 foster mother of young Timmy Martin, whose collie was the eponymous star of the series.
Even with playing a mother figure, Lockhart adeptly avoided being overshadowed by the smart dog. She described the program as “a fairy tale about people on a rural property in which the dog resolves all the problems in 22 minutes, in time for the last advertisement”. After she departed the series, Lockhart commented: “In six chaste years of playing a rural spouse and mother, I was rarely permitted to peck my co-star on the cheek.”
Starring in Lost in Space
Lockhart went directly into another hit, 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 scientists exploring distant planets. Lockhart had to spend most of her time deftly trying to survive special effects. As the series progressed, the storyline became less and less about this space family and more about the boy and his friendship with a robot, and the timid antagonist Dr Zachary Smith.
Beginnings in Entertainment
Lockhart’s feature film first role, at the young age of 13, had come as Belinda Cratchit in A Christmas Carol (1938). In the parts of her parents, Bob and Mrs Cratchit, were her actual parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canadian-born Gene were both actors in many of films, as well as on stage, it was almost certain that June, who was born in New York, would enter the entertainment industry.
Her first stage appearance, at the tender age of six, came in a non-musical role in an opera at the Metropolitan Opera in New York (1931).
Move to Hollywood and Movie Roles
When her parent was offered a contract by a motion picture studio, after his success on Broadway, she relocated with her parents to Hollywood, where Gene made around 300 films. After attending school in Beverly Hills, June started her career in films, mostly in small 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 family party, whose schedule is arranged spitefully to stop Lockhart interacting with her brother.
More importantly, although she did not realize 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 owners. In the later film, Lockhart played the now grown-up character.
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 minds of the producers when it came to casting the Lassie TV series 13 years later.
Shift to Television and Broadway Success
Although she was offered major roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her film career was stagnating and that television would be the solution. 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 best newcomer.
A further substantial run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a physician and mother figure. She also featured frequently in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy workload continued for the next 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 presenter finds a stray collie, and in another sitcom in 1995 as the mother of a restaurant manager.
Final Roles and Contributions
Her final TV appearance came in 2021 as the voice of Alpha Control in an episode of a streaming service’s new version of Lost in Space. In the big screen 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 first series had been to later astronauts, and often participated in the organization’s launches and other events. In 2013 her work as a volunteer representative brought her its Exceptional Public Achievement Medal.
Among her limited subsequent feature films was the fantasy, Troll (1986) in which she portrayed a witch, 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 medical officer. In addition to Anne, they had a second daughter, June. That marriage ended in separation, as did her subsequent marriage, to John Lindsay, an designer.
She is remembered by her children and four grandkids.
