Starting her career in cinema, June Lockhart, who died aged 100, achieved her biggest success after switching largely to television. Having been given limited chances to shine in movies from her first appearance as a youngster in 1938 until 1947, she thrived on television in many popular series, most notably in Lassie.
Her Memorable Role in Lassie
Stepping in from another actress in 1958, Lockhart remained in the show until 1964. She played Ruth Martin, wed to agriculturalist Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose collie was the eponymous hero of the series.
In her part as a homemaker, Lockhart somehow managed to avoid being completely upstaged by the clever dog. 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 departed the series, Lockhart remarked: “In six sexless years of playing a rural spouse and mother, I was rarely allowed to kiss my co-star on the face.”
Journey into Lost in Space
Lockhart went straight into another hit, Lost in Space (1965-68), a partly comedic science fiction series aimed primarily at young audiences and based by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two scientists exploring distant planets. Lockhart had to spend the majority of her time skillfully trying to survive visual effects. As the show progressed, the narrative became increasingly less about this space family and increasingly about the young son and his bond with a robot, and the cowardly villain Dr Zachary Smith.
Initial Career and Family Background
Lockhart’s feature film first role, at the young age of 13, had come as Belinda Cratchit in A Christmas Carol (1938). In the roles of her mother and father, Bob and Mrs Cratchit, were her real-life parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canadian-born Gene were both actors in dozens of films, as well as on theater, it was almost certain that June, who was born in New York, would enter the entertainment industry.
Her first theatrical 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 parent was given a deal by a film studio, after his success on Broadway, she moved with her parents to Hollywood, where Gene made approximately 300 films. After attending school in Beverly Hills, June started her career in films, mostly in small roles in prestigious 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 filled maliciously to prevent Lockhart interacting with her sibling.
More significantly, although she did not realize it at the time, was Son of Lassie (1945). It was one of several sequels to the extremely successful Lassie Come Home (1943), in which a young star had played the female character who assists the dog to escape to the family. In the subsequent film, Lockhart played the now adult character.
The loving 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 casting the Lassie TV series 13 years later.
Television and Theater Career
Although she was given leading roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her film career was stagnating and that TV would be the answer. Before going in a new direction, she won praise 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 rural hotel, where Lockhart is a physician and maternal character. 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 talkshow, where the presenter finds a stray collie, and in another sitcom in 1995 as the mother of a dining manager.
Later Roles and Contributions
Her last TV credit came in 2021 as the voice of Alpha Control in an episode of a streaming service’s new version of Lost in Space. In the movie 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 original series had been to later astronauts, and often participated in the organization’s launches and other events. In 2013 her work as a unpaid representative brought her its Exceptional Public Achievement Medal.
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.
Personal Life and Family
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 divorce, as did her subsequent marriage, to John Lindsay, an architect.
She is remembered by her children and four grandchildren.
