June Lockhart, who passed away at the remarkable age of 100, began her professional journey in films, but gained recognition after transitioning almost entirely to TV. Having been given limited opportunities to excel in films from her first appearance as a child in 1938 until 1947, she thrived on TV in many beloved series, most notably in Lassie.
Her Memorable Role in Lassie
Taking over from a previous star in 1958, Lockhart remained in the series until 1964. She played Ruth Martin, wed to agriculturalist Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose dog was the titular star of the series.
Even with playing a mother figure, Lockhart adeptly avoided being overshadowed by the brilliant dog. She described the program as “a fantasy about people on a farm in which the dog resolves all the problems in 22 minutes, in time for the last advertisement”. After she left the series, Lockhart commented: “In six sexless years of playing a rural spouse and parent, I was rarely allowed 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 semi-spoof sci-fi series aimed mostly at young audiences and based by The Swiss Family Robinson. Lockhart and her co-star played Maureen and John Robinson, two scientists investigating alien planets. Lockhart had to spend the majority of her time deftly trying to navigate visual effects. As the show continued, the narrative became less and less about this interstellar clan and increasingly about the young son and his bond with a robot, and the cowardly villain Dr Zachary Smith.
Beginnings in Entertainment
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 performers in dozens of movies, as well as on stage, it was nearly inevitable that June, who was born in New York, would enter show business.
Her first stage appearance, at the age of six, came in a non-singing role in an musical production at the Metropolitan Opera in New York (1931).
Cinema Work
When her father was offered a deal by a film studio, after his success on Broadway, she relocated with her family to Hollywood, where Gene made around 300 films. After going to school in Beverly Hills, June began her career in films, mainly in minor 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 family party, whose schedule is filled maliciously to prevent Lockhart interacting with her brother.
More significantly, although she did not realize 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 another actress had played the girl who assists the canine to escape to the family. In the later film, Lockhart played the now adult character.
The loving way in which she handled both Lassie and her offspring, Laddie, hero of a World War II adventure in enemy-held Norway, was in the minds of the producers when it came to casting the Lassie TV series 13 years later.
Shift to Television and Stage Success
Although she was offered major roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her film career was getting her nowhere and that TV would be the answer. Before embarking in a different direction, she won praise on Broadway in For Love or Money (1947), a comedy for which she won a Tony award as most promising newcomer.
A further substantial run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a physician and mother figure. She also appeared frequently in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy schedule persisted for the following five decades, with a regular role in General Hospital between 1984 and 1998. Among her many one-off appearances were as the actress in a 1988 episode of a comedy series, where the host finds a stray collie, and in another sitcom in 1995 as the parent of a dining manager.
Later Roles and Achievements
Her last TV appearance came in 2021 as the narration of Alpha Control in an episode of a digital platform’s remake of Lost in Space. In the big screen version featuring famous actors (1998), she had a holographic cameo as a school principal. She took pleasure 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 few subsequent feature films was the fantasy, Troll (1986) in which she played a witch, with her own daughter, Anne Lockhart, playing her earlier self.
Personal Details
In 1951 she wed 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 designer.
She is survived by her daughters and four grandkids.
