Starting her career in films, June Lockhart, who died aged 100, achieved her biggest success after shifting predominantly to the small screen. Having been offered few chances to shine in films from her first appearance as a child in 1938 until 1947, she thrived on TV in numerous popular series, especially in Lassie.
Her Iconic Role in Lassie
Stepping in from another actress in 1958, Lockhart continued in the series until 1964. She played Ruth Martin, married to agriculturalist Paul Martin and the adoptive mother of young Timmy Martin, whose dog was the titular star of the series.
In her role as a homemaker, Lockhart somehow succeeded to avoid being totally overshadowed by the clever canine. She described the program as “a fantasy about people on a rural property in which the canine resolves all the issues in 22 minutes, in time for the last commercial”. After she left the series, Lockhart commented: “In six chaste years of playing a rural spouse and parent, I was hardly ever permitted to kiss my on-screen husband on the face.”
Starring in Lost in Space
Lockhart went directly into another hit, Lost in Space (1965-68), a partly comedic science fiction series aimed primarily 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 the majority of her time deftly trying to survive visual effects. As the series continued, the storyline became increasingly less about this interstellar clan and more about the young son and his bond with a mechanical being, and the cowardly antagonist Dr Zachary Smith.
Early 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 roles of her parents, Bob and Mrs Cratchit, were her actual parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canadian-born Gene were both performers in dozens of films, as well as on stage, it was almost inevitable that June, who was born in New York, would join show business.
Her first stage performance, at the tender age of six, came in a non-musical role in an opera at the Metropolitan Opera in New York (1931).
Hollywood Work
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 going to school in Beverly Hills, June started her professional life in films, mostly in minor roles in acclaimed 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 arranged maliciously to stop Lockhart dancing with her sibling.
More importantly, 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 a young star had played the girl who assists the dog to escape to the family. In the subsequent film, Lockhart played the now adult character.
The affectionate way in which she interacted with both Lassie and her offspring, Laddie, hero of a World War II story in Nazi-occupied Norway, was in the consideration of the producers when it came to selecting the Lassie TV series 13 years later.
TV and Theater Career
Although she was given major roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her film career was stagnating and that television would be the solution. 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 additional significant run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a physician 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 following five decades, with a regular 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 restaurant manager.
Final Roles and Contributions
Her last 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 big screen 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 participated in the agency’s launches and other events. In 2013 her work as a unpaid representative brought her its prestigious award.
Among her limited later 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 doctor. In addition to Anne, they had a second daughter, June. That marriage ended in divorce, as did her second marriage, to John Lindsay, an designer.
She is remembered by her children and four grandkids.
