Launching her career in films, June Lockhart, who passed on aged 100, achieved her greatest success after shifting predominantly to the small screen. Having been given few opportunities to shine in movies from her first appearance as a youngster in 1938 until 1947, she thrived on television in many popular series, most notably in Lassie.
Her Memorable Role in Lassie
Stepping in from a previous star 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 dog was the eponymous hero of the series.
In her role as a housewife, Lockhart somehow managed to avoid being completely overshadowed by the intelligent dog. She described the show as “a fantasy about people on a farm in which the canine resolves all the problems in 22 minutes, in time for the last advertisement”. After she left the show, Lockhart commented: “In six chaste years of playing a country spouse and mother, I was hardly ever permitted to peck my co-star on the face.”
Starring in Lost in Space
Lockhart went straight into a second successful series, Lost in Space (1965-68), a semi-spoof science fiction series targeted primarily at children and inspired by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two researchers exploring distant planets. Lockhart had to spend most of her time skillfully trying to survive visual effects. As the show continued, the storyline became less and less about this interstellar family and more about the young son and his bond with a mechanical being, and the cowardly villain Dr Zachary Smith.
Beginnings in Show Business
Lockhart’s movie 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 Canada-native Gene were both performers in many of movies, as well as on stage, it was nearly inevitable that June, who was born in New York, would join show business.
Her first stage performance, at the 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 deal 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 professional life 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 charming as a New Yorker at a household party, whose schedule is arranged spitefully to prevent Lockhart interacting with her brother.
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 extremely successful Lassie Come Home (1943), in which a young star had played the female character who assists the canine to return to the owners. In the subsequent film, Lockhart played the now adult character.
The affectionate way in which she interacted with both Lassie and her offspring, Laddie, protagonist of a wartime story in enemy-held Norway, was in the minds of the producers when it came to casting the Lassie TV series 13 years later.
Television and Stage Career
Although she was offered leading roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her movie career was getting her nowhere and that TV would be the solution. 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 country hotel, where Lockhart is a physician and maternal character. She also featured frequently 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 the actress in a 1988 episode of a talkshow, where the presenter finds a stray collie, and in another sitcom in 1995 as the parent of a dining manager.
Later Career and Impact
Her final TV credit 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 movie version starring famous actors (1998), she had a digital cameo as a school principal. She took joy 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 unpaid spokesperson brought her its Exceptional Public Achievement Medal.
Among her limited 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 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 divorce, as did her subsequent marriage, to John Lindsay, an architect.
She is survived by her children and four grandkids.
