Starting her career in films, June Lockhart, who died aged 100, achieved her biggest success after shifting predominantly to television. Having been given limited opportunities to shine in films from her first appearance as a youngster 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. Her role was Ruth Martin, wed to agriculturalist Paul Martin and the foster mother of young Timmy Martin, whose collie was the eponymous hero of the series.
In her role as a housewife, Lockhart somehow succeeded to avoid being completely upstaged by the clever canine. She described the show as “a fantasy about people on a farm in which the dog solves all the problems in 22 minutes, in time for the last commercial”. After she left the series, Lockhart commented: “In six sexless years of playing a country spouse and parent, I was rarely allowed to peck my co-star on the face.”
Featuring in Lost in Space
Lockhart went directly into another hit, Lost in Space (1965-68), a semi-spoof science fiction series aimed mostly at children and based 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 navigate visual effects. As the series continued, the narrative became less and less about this space clan and more about the young son and his bond with a mechanical being, and the timid villain Dr Zachary Smith.
Initial 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 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 movies, as well as on theater, it was almost inevitable that June, who was born in New York, would join show business.
Her first theatrical 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 Career
When her father was given a contract by a film studio, after his acclaim on Broadway, she relocated with her parents to Hollywood, where Gene made approximately 300 films. After going to school in Beverly Hills, June began her professional life in movies, mostly in minor 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 dance card is arranged maliciously to stop Lockhart dancing with her brother.
More significantly, although she did not realize it at the time, was Son of Lassie (1945). It was one of multiple sequels to the extremely 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 affectionate way in which she handled both Lassie and her son, Laddie, protagonist of a wartime adventure in enemy-held Norway, was in the consideration of the creators when it came to casting the Lassie TV series 13 years later.
Television and Theater Work
Although she was offered major roles in two thrillers, 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 answer. Before going 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 most promising newcomer.
A further significant run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a doctor and maternal character. She also featured 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 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 host finds a lost collie, and in another sitcom in 1995 as the mother of a dining manager.
Later Roles and Achievements
Her final TV credit came in 2021 as the narration of Alpha Control in an episode of a streaming service’s remake of Lost in Space. In the movie version featuring 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 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 subsequent feature films was the fantasy, Troll (1986) in which she portrayed a witch, with her own daughter, Anne Lockhart, playing her earlier self.
Private Information
In 1951 she wed John Maloney, a doctor and former Navy medical officer. In addition to Anne, they had another daughter, June. That union ended in separation, as did her second marriage, to John Lindsay, an architect.
She is survived by her children and four grandkids.
