Starting her career in cinema, June Lockhart, who died aged 100, achieved her greatest success after shifting largely to television. Having been given limited opportunities to shine in movies from her first appearance as a youngster in 1938 until 1947, she thrived on TV in many popular series, especially in Lassie.
Her Memorable Role in Lassie
Taking over from a previous star in 1958, Lockhart remained in the show until 1964. She played Ruth Martin, married to agriculturalist Paul Martin and the foster mother of seven-year-old Timmy Martin, whose dog was the titular hero of the series.
Even with playing a mother figure, Lockhart adeptly avoided being outshone by the brilliant dog. She characterized 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 commercial”. After she departed the show, Lockhart commented: “In six chaste years of playing a country wife and mother, I was rarely allowed to kiss my co-star on the face.”
Adventure into Lost in Space
Lockhart went straight into another hit, Lost in Space (1965-68), a partly comedic science fiction series aimed primarily at young audiences and based by The Swiss Family Robinson. Lockhart and another actor 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 progressed, the narrative became less and less about this interstellar family and more about the boy and his bond with a mechanical being, and the cowardly villain Dr Zachary Smith.
Start in Entertainment
Lockhart’s feature film debut, at the young 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 real-life parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canadian-born Gene were both performers in many of films, as well as on theater, it was almost certain that June, who was born in New York, would enter show business.
Her first theatrical performance, at the age of six, came in a non-musical role in an opera at the Metropolitan Opera in New York (1931).
Hollywood Career
When her father was given a contract by a motion picture studio, after his acclaim on Broadway, she moved with her family to Hollywood, where Gene made around 300 films. After attending school in Beverly Hills, June began her career 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 latter, she is delightful as a New Yorker at a family party, whose schedule is filled maliciously to stop Lockhart dancing with her brother.
More significantly, although she did not know it at the time, was Son of Lassie (1945). It was one of multiple sequels to the hugely successful Lassie Come Home (1943), in which another actress had played the girl who assists the canine to return to the family. 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 wartime adventure in enemy-held Norway, was in the consideration of the producers when it came to casting the Lassie TV series 13 years later.
Shift to Television and Broadway Achievement
Although she was offered major roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her movie career was stagnating and that television would be the solution. Before embarking in a new direction, she received praise 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 rural hotel, where Lockhart is a doctor and maternal character. She also appeared frequently in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic schedule persisted for the following five decades, with a regular role in General Hospital between 1984 and 1998. Among her many guest appearances were as herself in a 1988 episode of a talkshow, where the presenter finds a stray collie, and in another sitcom in 1995 as the mother of a restaurant manager.
Final Career and Impact
Her last TV appearance came in 2021 as the narration of Alpha Control in an episode of a streaming service’s remake 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 first series had been to later astronauts, and often attended the organization’s launches and other events. In 2013 her work as a volunteer spokesperson brought her its prestigious award.
Among her limited subsequent feature films was the fantasy, Troll (1986) in which she portrayed a sorceress, 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 another daughter, June. That union ended in separation, as did her subsequent marriage, to John Lindsay, an architect.
She is survived by her daughters and four grandkids.
