June Lockhart, who passed away at the age of 100, began her professional journey in movies, but gained recognition after moving almost entirely to TV. Having been given few opportunities to shine in films from her debut as a child in 1938 until 1947, she thrived on television in many beloved series, most notably in Lassie.
Her Memorable Role in Lassie
Stepping in from another actress in 1958, Lockhart continued in the series until 1964. She played Ruth Martin, married to farmer Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose dog was the titular star of the series.
Even with playing a housewife, Lockhart adeptly avoided being outshone by the brilliant dog. She described the show 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 left the series, Lockhart remarked: “In six sexless years of playing a country spouse and mother, I was rarely permitted to peck my co-star on the cheek.”
Adventure into Lost in Space
Lockhart went directly into another hit, Lost in Space (1965-68), a semi-spoof sci-fi series targeted primarily at young audiences and inspired by The Swiss Family Robinson. Lockhart and her co-star portrayed Maureen and John Robinson, two scientists exploring alien planets. Lockhart had to spend most of her time skillfully trying to survive special effects. As the show continued, the storyline became increasingly less about this interstellar clan and increasingly about the boy and his friendship with a robot, and the cowardly antagonist Dr Zachary Smith.
Initial Career and Family Influence
Lockhart’s movie debut, 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 real-life parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canadian-born Gene were both performers in many of movies, as well as on theater, it was almost inevitable that June, who was born in New York, would enter the entertainment industry.
Her first stage performance, at the age of six, came in a non-singing role in an musical production at the Metropolitan Opera in New York (1931).
Transition to Hollywood and Movie Roles
When her father was offered a deal by a motion picture studio, after his acclaim on Broadway, she moved with her family to Hollywood, where Gene made around 300 films. After attending school in Beverly Hills, June began her professional life in films, mainly in minor roles in prestigious pictures such as Sergeant York (1941), The White Cliffs of Dover (1942) and Meet Me in St Louis (1944). In the latter, she is charming as a New Yorker at a household party, whose dance card is filled maliciously to prevent 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 several follow-ups to the extremely successful Lassie Come Home (1943), in which another actress had played the female character who helps the dog to escape to the owners. In the subsequent film, Lockhart played the now adult version.
The affectionate way in which she handled both Lassie and her offspring, Laddie, hero of a World War II story in enemy-held Norway, was in the consideration of the producers when it came to casting the Lassie TV series 13 years later.
Television and Theater Career
Although she was offered major roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her movie career was stagnating and that TV would be the answer. Before embarking in a new 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 further 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 continued for the next five decades, with a regular role in General Hospital between 1984 and 1998. Among her many one-off appearances were as herself 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 restaurant manager.
Later Career and Impact
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 movie 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 organization’s launches and other events. In 2013 her work as a unpaid spokesperson brought her its prestigious award.
Among her few later feature films was the fantasy, Troll (1986) in which she played a sorceress, with her own daughter, Anne Lockhart, playing her younger self.
Private Details
In 1951 she wed John Maloney, a physician and former Navy doctor. In addition to Anne, they had another daughter, June. That union ended in divorce, as did her subsequent marriage, to John Lindsay, an architect.
She is remembered by her children and four grandchildren.
