June Lockhart, who passed away at the remarkable age of 100, began her professional journey in movies, but gained recognition after moving almost exclusively to television. Having been given few chances to shine in movies from her debut as a youngster in 1938 until 1947, she excelled on TV in numerous popular series, most notably in Lassie.
Her Iconic Role in Lassie
Taking over from another actress in 1958, Lockhart continued in the show until 1964. She played Ruth Martin, wed to agriculturalist Paul Martin and the foster mother of seven-year-old Timmy Martin, whose dog was the titular star of the series.
In her role as a housewife, Lockhart somehow succeeded to avoid being totally upstaged by the clever canine. She characterized the program as “a fairy tale about families on a farm in which the canine solves all the problems in 22 minutes, in time for the last commercial”. After she left the show, Lockhart remarked: “In six sexless years of playing a rural spouse and parent, I was hardly ever permitted to kiss my co-star on the cheek.”
Adventure into Lost in Space
Lockhart went directly into another hit, Lost in Space (1965-68), a partly comedic science fiction series aimed mostly at children and based by The Swiss Family Robinson. Lockhart and her co-star played Maureen and John Robinson, two researchers investigating distant planets. Lockhart had to spend most of her time deftly trying to navigate visual effects. As the show progressed, 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.
Early Career and Family Influence
Lockhart’s feature film debut, 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 actual parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canada-native Gene were both actors in dozens of movies, as well as on stage, 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-singing role in an musical production at the Metropolitan Opera in New York (1931).
Move to Hollywood and Movie Roles
When her parent was given a deal by a film studio, after his acclaim on Broadway, she moved with her parents to Hollywood, where Gene made approximately 300 films. After going to school in Beverly Hills, June started her career in films, mostly in small 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 filled maliciously 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 sequels to the extremely successful Lassie Come Home (1943), in which a young star had played the girl who assists the dog to return to the owners. In the subsequent film, Lockhart played the now adult version.
The loving way in which she interacted with both Lassie and her son, Laddie, hero of a wartime story in enemy-held Norway, was in the consideration of the producers when it came to casting the Lassie TV series 13 years later.
Shift to Television and Broadway Success
Although she was given major roles in two thrillers, 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 new direction, she received acclaim on Broadway in For Love or Money (1947), a humorous play for which she won a Tony award as most promising newcomer.
A further substantial run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a doctor and maternal character. She also featured frequently in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic schedule persisted for the following five decades, with a recurring role in General Hospital between 1984 and 1998. Among her many one-off 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 dining manager.
Later Career and Legacy
Her last TV appearance came in 2021 as the voice 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 later 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 portrayed a witch, with her own daughter, Anne Lockhart, playing her earlier self.
Private Details
In 1951 she married John Maloney, a doctor and former Navy doctor. In addition to Anne, they had another daughter, June. That marriage ended in divorce, as did her subsequent marriage, to John Lindsay, an designer.
She is survived by her daughters and four grandchildren.
