June Lockhart, who passed away at the remarkable age of 100, began her professional journey in movies, but achieved recognition after moving almost exclusively to TV. Having been given limited opportunities to shine in films from her first appearance 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. Her role was Ruth Martin, married to agriculturalist Paul Martin and the foster mother of seven-year-old Timmy Martin, whose dog was the eponymous star of the series.
Even with playing a housewife, Lockhart skillfully avoided being outshone by the smart dog. She described the show as “a fairy tale about families on a farm in which the dog resolves all the problems in 22 minutes, in time for the last advertisement”. After she departed the show, Lockhart remarked: “In six chaste years of playing a rural spouse and parent, I was rarely allowed to kiss my on-screen husband on the cheek.”
Journey into Lost in Space
Lockhart went directly into a second hit, Lost in Space (1965-68), a semi-spoof science fiction series aimed mostly at young audiences and based by The Swiss Family Robinson. Lockhart and another actor portrayed Maureen and John Robinson, two researchers exploring distant planets. Lockhart had to spend most of her time skillfully trying to survive special effects. As the series continued, the narrative became increasingly less about this interstellar clan and more about the boy and his bond with a mechanical being, and the cowardly villain Dr Zachary Smith.
Beginnings in Entertainment
Lockhart’s movie first role, 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 UK-native Kathleen and Canadian-born Gene were both performers in many of movies, as well as on stage, it was almost certain that June, who was born in New York, would join show business.
Her first theatrical performance, at the tender age of six, came in a non-singing role in an opera at the Metropolitan Opera in New York (1931).
Hollywood Work
When her parent was given a contract by a motion picture studio, after his acclaim on Broadway, she relocated with her parents to Hollywood, where Gene made around 300 films. After going to school in Beverly Hills, June started her professional life 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 charming as a New Yorker at a family party, whose schedule is arranged spitefully to stop 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 escape to the owners. In the subsequent film, Lockhart played the now adult character.
The loving way in which she interacted with both Lassie and her offspring, Laddie, hero of a wartime story in Nazi-occupied Norway, was in the minds of the creators when it came to casting the Lassie TV series 13 years later.
Television and Theater Work
Although she was given leading roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her film career was stagnating and that TV would be the solution. Before going in a new direction, she won acclaim on Broadway in For Love or Money (1947), a comedy for which she won a Tony award as best newcomer.
A further significant run came with Petticoat Junction (1968-70), set in a country 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 hectic workload continued for the next 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 comedy series, where the host finds a lost collie, and in another sitcom in 1995 as the parent of a dining manager.
Later Roles and Achievements
Her last TV credit came in 2021 as the voice of Alpha Control in an episode of a digital platform’s new version of Lost in Space. In the movie version featuring well-known actors (1998), she had a holographic cameo as a school principal. She took pleasure in learning how much of an influence the original series had been to future astronauts, and often participated in the organization’s launches and other events. In 2013 her work as a volunteer representative brought her its prestigious award.
Among her limited later feature films was the fantasy, Troll (1986) in which she played a witch, with her own daughter, Anne Lockhart, playing her earlier self.
Personal Life and Family
In 1951 she wed John Maloney, a doctor and former Navy doctor. In addition to Anne, they had another daughter, June. That marriage ended in separation, as did her second marriage, to John Lindsay, an architect.
She is remembered by her daughters and four grandchildren.
