June Lockhart, who passed away at the remarkable age of 100, started her career in films, but achieved recognition after transitioning almost entirely to TV. 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.
Her Iconic Role in Lassie
Stepping in from a previous star in 1958, Lockhart remained in the series until 1964. She played Ruth Martin, married to farmer Paul Martin and the foster mother of young Timmy Martin, whose dog was the eponymous hero of the series.
In her role as a housewife, Lockhart somehow succeeded to avoid being totally upstaged by the clever dog. She described the program as “a fairy tale about people on a farm in which the canine resolves all the issues in 22 minutes, in time for the last advertisement”. After she departed the show, Lockhart commented: “In six chaste years of playing a country spouse and parent, I was rarely permitted to kiss my co-star on the cheek.”
Journey into Lost in Space
Lockhart went directly into another hit, Lost in Space (1965-68), a semi-spoof sci-fi series targeted primarily at young audiences and inspired by The Swiss Family Robinson. Lockhart and her co-star portrayed Maureen and John Robinson, two scientists investigating distant planets. Lockhart had to spend most of her time skillfully trying to survive special effects. As the series progressed, the storyline became less and less about this space family and increasingly about the boy and his friendship 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 parts 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 dozens of films, as well as on stage, it was almost inevitable that June, who was born in New York, would enter show business.
Her first stage performance, at the tender age of six, came in a non-singing role in an opera at the Metropolitan Opera in New York (1931).
Move to Hollywood and Film Roles
When her father was given a deal by a film studio, after his success on Broadway, she relocated with her parents to Hollywood, where Gene made approximately 300 films. After attending school in Beverly Hills, June started her professional life in movies, mainly 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 charming as a New Yorker at a family party, whose dance card is arranged maliciously to prevent 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 follow-ups to the hugely successful Lassie Come Home (1943), in which a young star had played the girl who helps the canine to return to the owners. In the subsequent film, Lockhart played the now adult version.
The affectionate way in which she handled both Lassie and her son, Laddie, hero of a wartime adventure in enemy-held Norway, was in the minds of the creators when it came to selecting the Lassie TV series 13 years later.
Television and Stage Career
Although she was offered 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 solution. Before embarking in a different direction, she won praise on Broadway in For Love or Money (1947), a comedy for which she won a Tony award as best newcomer.
A further substantial run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a doctor and mother figure. She also appeared regularly in TV westerns 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 one-off appearances were as herself in a 1988 episode of a talkshow, where the host finds a lost collie, and in another sitcom in 1995 as the parent of a restaurant manager.
Later Career and Impact
Her last TV credit came in 2021 as the narration of Alpha Control in an episode of a digital platform’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 joy in learning how much of an influence the first series had been to future astronauts, and often participated in the organization’s launches and other events. In 2013 her work as a unpaid spokesperson brought her its Exceptional Public Achievement Medal.
Among her limited subsequent feature films was the fantasy, Troll (1986) in which she played a witch, with her own daughter, Anne Lockhart, playing her earlier self.
Personal Life and Family
In 1951 she married John Maloney, a physician and former Navy doctor. In addition to Anne, they had a second daughter, June. That union ended in separation, as did her subsequent marriage, to John Lindsay, an architect.
She is remembered by her daughters and four grandchildren.
