June Lockhart, who died at the age of 100, started her professional journey in movies, but gained recognition after moving almost entirely to TV. Having been offered limited chances to excel in movies from her debut as a youngster in 1938 until 1947, she excelled on TV in many beloved series, most notably in Lassie.
Her Memorable Role in Lassie
Taking over from another actress in 1958, Lockhart continued in the show until 1964. Her role was Ruth Martin, married to farmer Paul Martin and the foster mother of young Timmy Martin, whose dog was the titular hero of the series.
Even with playing a mother figure, Lockhart adeptly avoided being overshadowed by the smart dog. She described the show as “a fairy tale about people on a farm in which the canine solves all the problems in 22 minutes, in time for the last commercial”. After she left the show, Lockhart commented: “In six chaste years of playing a rural wife and parent, I was hardly ever allowed to peck my on-screen husband on the face.”
Starring in Lost in Space
Lockhart went directly into a second successful series, Lost in Space (1965-68), a partly comedic sci-fi series aimed mostly at children and inspired by The Swiss Family Robinson. Lockhart and her co-star played Maureen and John Robinson, two scientists exploring distant planets. Lockhart had to spend the majority of her time deftly trying to survive special effects. As the series continued, the storyline became increasingly less about this space family and increasingly about the boy and his friendship with a robot, and the timid villain Dr Zachary Smith.
Beginnings in Entertainment
Lockhart’s feature film debut, at the 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 real-life parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canada-native Gene were both actors in dozens of movies, as well as on stage, it was almost inevitable that June, who was born in New York, would join the entertainment industry.
Her first stage performance, at the age of six, came in a non-musical role in an musical production 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 acclaim on Broadway, she moved with her parents to Hollywood, where Gene made around 300 films. After going to school in Beverly Hills, June started her career in films, mainly 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 delightful as a New Yorker at a family party, whose schedule is arranged spitefully to prevent Lockhart dancing with her sibling.
More importantly, although she did not know it at the time, was Son of Lassie (1945). It was one of multiple follow-ups to the hugely successful Lassie Come Home (1943), in which another actress had played the girl who helps the canine to return to the owners. In the subsequent film, Lockhart played the now adult character.
The loving way in which she interacted with both Lassie and her son, Laddie, protagonist of a World War II story in enemy-held Norway, was in the minds of the creators when it came to casting 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 film career was getting her nowhere and that TV would be the answer. Before going in a different 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 significant run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a physician and mother figure. She also featured frequently in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy workload persisted for the next five decades, with a recurring role in General Hospital between 1984 and 1998. Among her many guest appearances were as the actress in a 1988 episode of a talkshow, where the host finds a lost collie, and in another sitcom in 1995 as the mother of a dining manager.
Final Career and Legacy
Her final TV credit came in 2021 as the narration of Alpha Control in an episode of a digital platform’s remake of Lost in Space. In the movie version featuring well-known actors (1998), she had a holographic cameo as a school principal. She took pleasure in learning how much of an influence the original series had been to future astronauts, and often attended the agency’s launches and other events. In 2013 her work as a volunteer representative brought her its prestigious award.
Among her few later feature films was the fantasy, Troll (1986) in which she portrayed a sorceress, with her own daughter, Anne Lockhart, playing her younger self.
Private Details
In 1951 she wed John Maloney, a physician and former Navy medical officer. In addition to Anne, they had another daughter, June. That marriage ended in divorce, as did her subsequent marriage, to John Lindsay, an architect.
She is remembered by her daughters and four grandkids.
