June Lockhart, who died at the age of 100, began her professional journey in movies, but achieved recognition 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 excelled on television in numerous popular series, most notably in Lassie.
Her Memorable Role in Lassie
Stepping in from another actress in 1958, Lockhart continued in the show until 1964. She played Ruth Martin, married to agriculturalist Paul Martin and the foster mother of young Timmy Martin, whose dog was the eponymous star of the series.
Despite playing a housewife, Lockhart adeptly avoided being outshone by the brilliant animal star. 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 advertisement”. After she left the show, Lockhart commented: “In six chaste years of playing a country spouse and parent, I was rarely permitted to peck my co-star on the face.”
Journey into Lost in Space
Lockhart went directly into a second hit, Lost in Space (1965-68), a partly comedic 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 scientists exploring distant planets. Lockhart had to spend the majority of her time skillfully trying to navigate special effects. As the show continued, the narrative 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.
Initial Career and Family Background
Lockhart’s movie first role, at the 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 British-born Kathleen and Canada-native Gene were both performers in dozens of movies, as well as on theater, it was almost certain that June, who was born in New York, would join the entertainment industry.
Her first stage performance, 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 father was given a deal by a film studio, after his success on Broadway, she moved with her family to Hollywood, where Gene made approximately 300 films. After going to school in Beverly Hills, June began her professional life in films, mainly 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 latter, she is charming as a New Yorker at a household party, whose schedule is arranged spitefully 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 multiple follow-ups to the extremely successful Lassie Come Home (1943), in which another actress had played the female character who assists the dog to escape to the owners. In the later film, Lockhart played the now grown-up character.
The loving way in which she interacted with both Lassie and her offspring, Laddie, protagonist of a wartime adventure in enemy-held Norway, was in the minds of the producers when it came to casting the Lassie TV series 13 years later.
TV and Stage Work
Although she was given major roles in two suspense films, 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 embarking in a new direction, she received acclaim on Broadway in For Love or Money (1947), a comedy for which she won a Tony award as best newcomer.
A additional significant run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a doctor and mother figure. She also appeared frequently in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic workload 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 comedy series, where the host finds a lost collie, and in another sitcom in 1995 as the mother of a restaurant manager.
Later Career and Legacy
Her final TV credit came in 2021 as the narration of Alpha Control in an episode of a streaming service’s remake of Lost in Space. In the big screen version featuring well-known 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 agency’s launches and other events. In 2013 her work as a unpaid representative brought her its prestigious award.
Among her few subsequent feature films was the fantasy, Troll (1986) in which she portrayed a sorceress, 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 separation, as did her second marriage, to John Lindsay, an architect.
She is remembered by her daughters and four grandchildren.
