Starting her career in cinema, June Lockhart, who passed on aged 100, found her biggest success after shifting largely to television. Having been offered few opportunities to shine in movies from her debut as a child in 1938 until 1947, she thrived on TV in numerous popular series, most notably in Lassie.
Her Memorable Role in Lassie
Stepping in from another actress in 1958, Lockhart continued in the series until 1964. She played Ruth Martin, wed to agriculturalist Paul Martin and the foster mother of young Timmy Martin, whose dog was the eponymous star of the series.
Despite playing a housewife, Lockhart skillfully avoided being overshadowed by the smart dog. She described the program as “a fantasy about families 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 show, Lockhart commented: “In six sexless years of playing a country spouse and parent, I was rarely allowed to peck my co-star on the cheek.”
Featuring in Lost in Space
Lockhart went directly into a second successful series, Lost in Space (1965-68), a partly comedic sci-fi series aimed primarily at children and based by The Swiss Family Robinson. Lockhart and her co-star portrayed Maureen and John Robinson, two scientists investigating distant planets. Lockhart had to spend the majority of her time deftly trying to survive visual effects. As the series continued, the narrative became increasingly less about this space family and increasingly about the boy and his friendship with a mechanical being, and the cowardly villain Dr Zachary Smith.
Start in Show Business
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 real-life parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canadian-born Gene were both actors in many of movies, as well as on theater, it was almost certain that June, who was born in New York, would enter the entertainment industry.
Her first theatrical performance, at the tender age of six, came in a non-musical role in an opera at the Metropolitan Opera in New York (1931).
Transition to Hollywood and Movie Roles
When her father was given a deal by a film studio, after his success on Broadway, she moved with her family to Hollywood, where Gene made approximately 300 films. After going to school in Beverly Hills, June began her professional life in movies, mostly 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 family party, whose dance card is filled maliciously to prevent Lockhart dancing 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 another actress had played the female character who helps the canine to return to the owners. In the later film, Lockhart played the now adult version.
The loving way in which she handled both Lassie and her son, Laddie, protagonist of a World War II story in Nazi-occupied Norway, was in the minds of the creators when it came to selecting the Lassie TV series 13 years later.
Transition to Television and Stage Achievement
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 stagnating and that TV would be the answer. Before going in a new direction, she received acclaim on Broadway in For Love or Money (1947), a comedy for which she won a Tony award as most promising newcomer.
A further significant 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 westerns 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 recurring 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 lost collie, and in another sitcom in 1995 as the parent of a restaurant manager.
Final Roles and Contributions
Her final TV appearance came in 2021 as the narration of Alpha Control in an episode of a streaming service’s new version of Lost in Space. In the big screen version featuring well-known actors (1998), she had a holographic cameo as a school principal. She took joy in learning how much of an influence the original series had been to later astronauts, and often participated in the organization’s launches and other events. In 2013 her work as a volunteer spokesperson brought her its Exceptional Public Achievement Medal.
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 earlier self.
Private Details
In 1951 she married John Maloney, a physician and former Navy medical officer. In addition to Anne, they had another daughter, June. That union ended in divorce, as did her second marriage, to John Lindsay, an architect.
She is survived by her children and four grandchildren.
