June Lockhart, who died at the remarkable age of 100, started her career in movies, but achieved fame after moving almost entirely to TV. Having been offered few chances to shine in films from her debut as a child in 1938 until 1947, she thrived on TV in many beloved series, most notably in Lassie.
Becoming Ruth Martin on Lassie
Stepping in from a previous star in 1958, Lockhart remained in the series until 1964. She played 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 role as a housewife, Lockhart somehow managed to avoid being totally overshadowed by the intelligent dog. She described the program as “a fantasy about families on a farm in which the canine resolves all the problems in 22 minutes, in time for the last commercial”. After she departed the series, Lockhart commented: “In six chaste years of playing a rural wife and parent, I was hardly ever allowed to peck my co-star on the face.”
Starring in Lost in Space
Lockhart went straight into another successful series, Lost in Space (1965-68), a semi-spoof sci-fi series targeted primarily at young audiences and based by The Swiss Family Robinson. Lockhart and her co-star portrayed Maureen and John Robinson, two researchers exploring alien planets. Lockhart had to spend the majority of her time skillfully trying to navigate visual effects. As the series continued, the storyline became increasingly less about this interstellar clan and increasingly about the boy and his friendship with a mechanical being, and the timid antagonist Dr Zachary Smith.
Start in Show Business
Lockhart’s feature film debut, at the young 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 real-life parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canada-native Gene were both performers in many of films, as well as on theater, it was nearly inevitable that June, who was born in New York, would join show business.
Her first stage performance, at the age of six, came in a non-singing role in an opera at the Metropolitan Opera in New York (1931).
Move to Hollywood and Film Roles
When her parent was offered a deal by a motion picture 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 career in films, mainly 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 last one, she is delightful as a New Yorker at a household party, whose schedule is arranged 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 owners. In the later film, Lockhart played the now adult character.
The affectionate way in which she handled both Lassie and her offspring, Laddie, hero of a wartime story in enemy-held Norway, was in the minds of the creators when it came to selecting the Lassie TV series 13 years later.
Television and Theater Work
Although she was offered leading roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her film career was getting her nowhere 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 comedy for which she won a Tony award as best newcomer.
A further substantial run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a physician and maternal character. She also appeared regularly in TV cowboy shows 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 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 host finds a lost collie, and in another sitcom in 1995 as the mother of a dining manager.
Final Roles and Achievements
Her final TV appearance came in 2021 as the narration of Alpha Control in an episode of a digital platform’s remake of Lost in Space. In the big screen version starring well-known actors (1998), she had a holographic cameo as a school principal. She took pleasure in learning how much of an inspiration 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 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 wed John Maloney, a physician and former Navy medical officer. In addition to Anne, they had a second daughter, June. That union ended in divorce, as did her second marriage, to John Lindsay, an designer.
She is remembered by her daughters and four grandchildren.
