June Lockhart, who passed away at the age of 100, began her professional journey in movies, but gained fame after moving almost entirely to TV. Having been given limited chances to excel in films from her first appearance as a youngster in 1938 until 1947, she excelled on television in numerous beloved series, especially in Lassie.
Portraying Ruth Martin on Lassie
Taking over from a previous star in 1958, Lockhart continued in the show until 1964. Her role was Ruth Martin, married to agriculturalist Paul Martin and the adoptive mother of young Timmy Martin, whose collie was the titular star of the series.
Despite playing a mother figure, Lockhart adeptly avoided being overshadowed by the smart animal star. She characterized the show as “a fantasy about people on a rural property in which the dog solves all the problems in 22 minutes, in time for the last advertisement”. After she departed the series, Lockhart commented: “In six sexless years of playing a rural spouse and mother, I was rarely permitted to peck my co-star on the face.”
Adventure into Lost in Space
Lockhart went directly into a second hit, Lost in Space (1965-68), a partly comedic sci-fi series targeted primarily at young audiences and based by The Swiss Family Robinson. Lockhart and her co-star portrayed Maureen and John Robinson, two scientists investigating alien planets. Lockhart had to spend most of her time deftly trying to navigate visual effects. As the series progressed, the storyline became less and less about this space clan and increasingly about the boy and his bond with a mechanical being, and the cowardly villain Dr Zachary Smith.
Start in Show Business
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 mother and father, Bob and Mrs Cratchit, were her actual parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canada-native Gene were both performers in dozens of films, as well as on stage, it was almost inevitable 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 opera at the Metropolitan Opera in New York (1931).
Cinema Career
When her parent was given a deal by a film studio, after his acclaim on Broadway, she moved with her parents to Hollywood, where Gene made approximately 300 films. After attending school in Beverly Hills, June began her professional life in movies, mostly 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 latter, she is delightful as a New Yorker at a household party, whose dance card is arranged maliciously to stop Lockhart dancing with her sibling.
More significantly, although she did not realize 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 girl who helps the dog to escape to the owners. In the later film, Lockhart played the now adult version.
The affectionate way in which she interacted with both Lassie and her son, Laddie, protagonist of a World War II adventure in Nazi-occupied Norway, was in the minds of the producers when it came to casting the Lassie TV series 13 years later.
Television and Theater Work
Although she was given leading roles in two suspense films, 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 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 doctor and mother figure. She also featured regularly in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic schedule persisted for the following five decades, with a recurring 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 stray collie, and in another sitcom in 1995 as the parent of a restaurant manager.
Final Career and Impact
Her final TV credit came in 2021 as the voice of Alpha Control in an episode of a digital platform’s remake of Lost in Space. In the movie version featuring famous actors (1998), she had a digital cameo as a school principal. She took pleasure in learning how much of an inspiration the first series had been to later astronauts, and often participated in the organization’s launches and other events. In 2013 her work as a volunteer 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.
Personal Life and Family
In 1951 she married John Maloney, a doctor and former Navy medical officer. In addition to Anne, they had a second daughter, June. That union ended in separation, as did her subsequent marriage, to John Lindsay, an architect.
She is survived by her daughters and four grandkids.
