Launching her career in films, June Lockhart, who died aged 100, found her biggest success after switching predominantly to television. Having been offered few chances to excel in movies from her first appearance as a child in 1938 until 1947, she excelled on television in numerous popular series, most notably in Lassie.
Her Iconic Role in Lassie
Stepping in from another actress in 1958, Lockhart continued in the show until 1964. Her role was Ruth Martin, wed to farmer Paul Martin and the foster mother of young Timmy Martin, whose collie was the titular star of the series.
In her part as a homemaker, Lockhart somehow succeeded to avoid being totally upstaged by the clever canine. She characterized the program as “a fantasy about people on a rural property in which the canine solves all the issues in 22 minutes, in time for the last advertisement”. After she departed the series, Lockhart commented: “In six sexless years of playing a country wife and mother, I was hardly ever permitted to peck my on-screen husband on the face.”
Adventure into Lost in Space
Lockhart went directly into another hit, Lost in Space (1965-68), a partly comedic sci-fi series targeted mostly at young audiences and inspired by The Swiss Family Robinson. Lockhart and her co-star portrayed Maureen and John Robinson, two researchers investigating distant planets. Lockhart had to spend most of her time deftly trying to survive special effects. As the show continued, the narrative became less and less about this interstellar clan and increasingly about the young son and his friendship with a robot, and the timid villain Dr Zachary Smith.
Beginnings in Entertainment
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 actual parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canada-native Gene were both actors in many of films, as well as on theater, it was nearly inevitable that June, who was born in New York, would join the entertainment industry.
Her first theatrical appearance, at the age of six, came in a non-singing role in an musical production at the Metropolitan Opera in New York (1931).
Move to Hollywood and Film Roles
When her parent was offered a deal by a film studio, after his acclaim on Broadway, she relocated with her parents to Hollywood, where Gene made approximately 300 films. After attending school in Beverly Hills, June started her professional life in movies, mostly in small roles in acclaimed 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 maliciously to prevent 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 hugely successful Lassie Come Home (1943), in which a young star had played the female character who assists the canine to return to the family. In the later film, Lockhart played the now grown-up character.
The loving way in which she handled both Lassie and her offspring, Laddie, protagonist of a World War II adventure in Nazi-occupied Norway, was in the minds of the producers when it came to casting the Lassie TV series 13 years later.
Transition to Television and Stage Success
Although she was offered major roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her film career was getting her nowhere and that television would be the solution. Before going in a different direction, she won praise on Broadway in For Love or Money (1947), a comedy for which she won a Tony award as best newcomer.
A additional substantial run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a doctor and maternal character. She also featured frequently in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy schedule 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 parent of a dining manager.
Later Career and Legacy
Her last TV appearance 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 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 future 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 few subsequent feature films was the fantasy, Troll (1986) in which she played a sorceress, with her own daughter, Anne Lockhart, playing her younger self.
Personal Information
In 1951 she wed John Maloney, a doctor and former Navy doctor. 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.
