June Lockhart, who died at the remarkable age of 100, began her career in movies, but gained recognition after transitioning almost exclusively to TV. Having been offered limited opportunities to excel in movies from her debut as a youngster in 1938 until 1947, she excelled on television in many popular series, especially in Lassie.
Her Iconic Role in Lassie
Taking over from a previous star in 1958, Lockhart remained in the series until 1964. Her role was Ruth Martin, wed to agriculturalist Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose collie was the titular hero of the series.
Despite playing a housewife, Lockhart adeptly avoided being overshadowed by the brilliant dog. She characterized the program as “a fairy tale about families on a farm in which the dog solves all the problems in 22 minutes, in time for the last commercial”. After she departed the series, Lockhart commented: “In six chaste years of playing a country spouse and mother, I was rarely permitted to peck my on-screen husband on the face.”
Starring in Lost in Space
Lockhart went straight into another hit, Lost in Space (1965-68), a partly comedic sci-fi series targeted mostly at children and based by The Swiss Family Robinson. Lockhart and another actor portrayed Maureen and John Robinson, two scientists exploring alien planets. Lockhart had to spend most of her time skillfully trying to navigate visual effects. As the show continued, the storyline became less and less about this interstellar clan and increasingly about the boy and his bond with a robot, and the cowardly villain Dr Zachary Smith.
Early Career and Family Background
Lockhart’s feature film first role, at the age of 13, had come as Belinda Cratchit in A Christmas Carol (1938). In the roles of her parents, Bob and Mrs Cratchit, were her actual parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canada-native 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 appearance, at the tender age of six, came in a non-singing role in an opera at the Metropolitan Opera in New York (1931).
Hollywood Work
When her parent was offered a contract by a film studio, after his acclaim on Broadway, she moved with her parents to Hollywood, where Gene made around 300 films. After attending school in Beverly Hills, June started her professional life 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 charming as a New Yorker at a household party, whose schedule is filled maliciously to prevent Lockhart dancing with her brother.
More significantly, although she did not know it at the time, was Son of Lassie (1945). It was one of several follow-ups to the hugely successful Lassie Come Home (1943), in which a young star had played the female character who assists the dog to return 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, hero of a wartime story in enemy-held Norway, was in the minds of the creators when it came to casting the Lassie TV series 13 years later.
TV and Stage Career
Although she was given leading roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her film career was getting her nowhere and that TV would be the solution. Before going in a different direction, she received praise on Broadway in For Love or Money (1947), a humorous play for which she won a Tony award as best newcomer.
A additional substantial run came with Petticoat Junction (1968-70), set in a rural 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 workload continued for the next five decades, with a regular role in General Hospital between 1984 and 1998. Among her many guest appearances were as the actress in a 1988 episode of a talkshow, where the presenter finds a lost collie, and in another sitcom in 1995 as the parent of a dining manager.
Later Career and Impact
Her final TV appearance came in 2021 as the voice of Alpha Control in an episode of a digital platform’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 sorceress, with her own daughter, Anne Lockhart, playing her younger self.
Private Information
In 1951 she married John Maloney, a physician and former Navy doctor. In addition to Anne, they had a second 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 grandkids.
