Launching her career in cinema, June Lockhart, who passed on aged 100, found her biggest success after shifting predominantly to the small screen. Having been given limited opportunities to shine in movies from her debut as a child in 1938 until 1947, she thrived on TV in numerous popular series, most notably in Lassie.
Her Memorable Role in Lassie
Taking over from another actress in 1958, Lockhart continued in the series until 1964. Her role was Ruth Martin, wed to agriculturalist Paul Martin and the adoptive mother of young Timmy Martin, whose dog was the titular star of the series.
In her part as a housewife, Lockhart somehow succeeded to avoid being totally overshadowed by the clever canine. She characterized the program as “a fairy tale about people on a farm in which the dog solves all the issues 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 mother, I was rarely allowed to peck my on-screen husband on the face.”
Journey into Lost in Space
Lockhart went straight into another hit, Lost in Space (1965-68), a semi-spoof science fiction series aimed mostly at children and inspired by The Swiss Family Robinson. Lockhart and her co-star portrayed Maureen and John Robinson, two researchers exploring alien planets. Lockhart had to spend the majority of her time deftly trying to navigate visual effects. As the series progressed, the storyline became increasingly less about this interstellar family and more about the boy and his friendship with a robot, and the timid villain Dr Zachary Smith.
Initial Career and Family Influence
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 UK-native Kathleen and Canadian-born Gene were both performers 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 theatrical appearance, at the tender age of six, came in a non-musical role in an opera at the Metropolitan Opera in New York (1931).
Cinema Career
When her parent was offered a contract by a motion picture studio, after his acclaim on Broadway, she moved with her parents to Hollywood, where Gene made around 300 films. After going to 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 last one, she is delightful as a New Yorker at a family party, whose schedule is filled maliciously to prevent Lockhart interacting with her sibling.
More importantly, although she did not know 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 girl who helps the dog to escape to the family. In the subsequent film, Lockhart played the now adult character.
The affectionate way in which she handled both Lassie and her son, Laddie, hero of a World War II adventure in Nazi-occupied Norway, was in the consideration of the creators when it came to selecting the Lassie TV series 13 years later.
Television and Theater Career
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 TV would be the answer. Before embarking 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 additional significant run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a physician and mother figure. She also appeared 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 next five decades, with a recurring role in General Hospital between 1984 and 1998. Among her many guest appearances were as herself 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 restaurant manager.
Final Roles and Achievements
Her final TV appearance 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 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 original series had been to future astronauts, and often participated in the agency’s launches and other events. In 2013 her work as a volunteer representative brought her its Exceptional Public Achievement Medal.
Among her few subsequent feature films was the fantasy, Troll (1986) in which she played a sorceress, with her own daughter, Anne Lockhart, playing her earlier self.
Personal Information
In 1951 she married John Maloney, a doctor and former Navy medical officer. In addition to Anne, they had another daughter, June. That marriage ended in separation, as did her second marriage, to John Lindsay, an designer.
She is remembered by her children and four grandchildren.
