Launching her career in films, June Lockhart, who passed on aged 100, achieved her biggest success after switching largely to the small screen. Having been given few opportunities to excel 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 Iconic Role in Lassie
Taking over from a previous star in 1958, Lockhart continued in the show until 1964. She played Ruth Martin, married to agriculturalist Paul Martin and the foster mother of seven-year-old Timmy Martin, whose collie was the titular 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 rural property in which the dog solves all the problems in 22 minutes, in time for the last commercial”. After she left the show, Lockhart commented: “In six sexless years of playing a country spouse and parent, I was rarely allowed to kiss my co-star on the face.”
Starring in Lost in Space
Lockhart went directly into a second successful series, Lost in Space (1965-68), a partly comedic sci-fi series targeted mostly at children and based by The Swiss Family Robinson. Lockhart and her co-star played Maureen and John Robinson, two researchers investigating alien planets. Lockhart had to spend the majority of her time skillfully trying to navigate visual effects. As the series progressed, the storyline became increasingly less about this interstellar clan and increasingly about the boy and his bond with a robot, and the cowardly villain 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 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 many of films, as well as on theater, it was nearly inevitable that June, who was born in New York, would enter show business.
Her first stage appearance, at the tender age of six, came in a non-musical role in an musical production at the Metropolitan Opera in New York (1931).
Cinema Work
When her father was given a deal by a film studio, after his acclaim on Broadway, she relocated with her family to Hollywood, where Gene made around 300 films. After attending school in Beverly Hills, June began her professional life in movies, 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 delightful as a New Yorker at a household party, whose dance card is arranged spitefully to stop Lockhart dancing with her sibling.
More importantly, although she did not know it at the time, was Son of Lassie (1945). It was one of multiple follow-ups to the hugely successful Lassie Come Home (1943), in which a young star had played the girl who assists the canine to escape to the owners. In the subsequent film, Lockhart played the now grown-up version.
The affectionate way in which she interacted with both Lassie and her offspring, Laddie, protagonist of a wartime story 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 Theater Work
Although she was given major roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her movie career was stagnating and that television would be the solution. Before embarking in a different direction, she received acclaim 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 country hotel, where Lockhart is a doctor and mother figure. She also appeared regularly in TV cowboy shows 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 presenter finds a stray collie, and in another sitcom in 1995 as the mother of a restaurant manager.
Final Career and Impact
Her last 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 famous 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 later astronauts, and often participated in the agency’s launches and other events. In 2013 her work as a volunteer spokesperson brought her its prestigious award.
Among her limited later feature films was the fantasy, Troll (1986) in which she portrayed a witch, with her own daughter, Anne Lockhart, playing her younger self.
Personal Details
In 1951 she married John Maloney, a doctor and former Navy medical officer. In addition to Anne, they had another daughter, June. That union ended in separation, as did her second marriage, to John Lindsay, an designer.
She is remembered by her daughters and four grandchildren.
