June Lockhart, who died at the age of 100, began her professional journey in films, but gained fame after moving almost entirely to TV. Having been given few opportunities to shine in films from her first appearance as a child in 1938 until 1947, she thrived on television in numerous beloved series, most notably in Lassie.
Her Memorable Role in Lassie
Taking over from a previous star in 1958, Lockhart remained in the series until 1964. She played Ruth Martin, married to agriculturalist Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose collie was the titular star of the series.
In her part as a housewife, Lockhart somehow managed to avoid being completely overshadowed by the intelligent dog. She characterized the show as “a fairy tale about people on a farm in which the canine resolves all the problems in 22 minutes, in time for the last advertisement”. After she departed the series, Lockhart remarked: “In six chaste years of playing a rural spouse and mother, I was rarely permitted to peck my on-screen husband on the cheek.”
Featuring in Lost in Space
Lockhart went straight into a second successful series, Lost in Space (1965-68), a partly comedic science fiction series aimed primarily at children and inspired by The Swiss Family Robinson. Lockhart and another actor portrayed Maureen and John Robinson, two researchers investigating alien planets. Lockhart had to spend most of her time deftly trying to survive visual effects. As the series progressed, the storyline became increasingly less about this space clan and more about the young son and his friendship with a robot, and the timid antagonist Dr Zachary Smith.
Start in Entertainment
Lockhart’s feature film first role, at the 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 real-life parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canadian-born Gene were both actors in dozens of films, as well as on theater, it was almost inevitable that June, who was born in New York, would enter show business.
Her first stage appearance, 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 parent was given a deal by a film studio, after his acclaim on Broadway, she relocated with her family to Hollywood, where Gene made around 300 films. After going to school in Beverly Hills, June began 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 spitefully to stop Lockhart interacting with her brother.
More importantly, although she did not realize it at the time, was Son of Lassie (1945). It was one of multiple follow-ups to the hugely successful Lassie Come Home (1943), in which a young star had played the female character who helps the canine to escape to the owners. In the later film, Lockhart played the now adult character.
The affectionate way in which she interacted with both Lassie and her offspring, Laddie, protagonist of a World War II story in enemy-held Norway, was in the consideration of the creators when it came to selecting the Lassie TV series 13 years later.
Transition to Television and Stage Success
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 getting her nowhere and that television would be the answer. Before going in a different direction, she received acclaim on Broadway in For Love or Money (1947), a humorous play 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 mother figure. She also appeared regularly 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 regular role in General Hospital between 1984 and 1998. Among her many guest appearances were as herself in a 1988 episode of a comedy series, where the host finds a stray collie, and in another sitcom in 1995 as the mother of a dining manager.
Final Career and Impact
Her final TV appearance came in 2021 as the narration of Alpha Control in an episode of a digital platform’s new version 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 joy 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 unpaid 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 younger self.
Private Information
In 1951 she married John Maloney, a physician and former Navy medical officer. In addition to Anne, they had a second daughter, June. That union ended in separation, as did her second marriage, to John Lindsay, an designer.
She is remembered by her daughters and four grandkids.
