Starting her career in films, June Lockhart, who passed on aged 100, achieved her greatest success after shifting predominantly to television. Having been offered limited chances to shine in movies from her first appearance as a child in 1938 until 1947, she thrived on TV in numerous popular series, most notably in Lassie.
Her Iconic Role in Lassie
Stepping in from another actress in 1958, Lockhart continued in the series until 1964. Her role was Ruth Martin, wed to farmer 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 program as “a fantasy 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 remarked: “In six chaste years of playing a rural wife and parent, I was rarely permitted to kiss 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 targeted mostly at young audiences and based by The Swiss Family Robinson. Lockhart and her co-star played Maureen and John Robinson, two scientists exploring alien planets. Lockhart had to spend the majority of her time skillfully trying to navigate visual effects. As the series progressed, the narrative became increasingly less about this interstellar family and increasingly about the young son and his bond with a mechanical being, and the timid antagonist Dr Zachary Smith.
Start in Entertainment
Lockhart’s feature film debut, 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 real-life parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canada-native Gene were both performers in dozens of movies, as well as on theater, it was nearly certain that June, who was born in New York, would join the entertainment industry.
Her first theatrical performance, at the tender age of six, came in a non-musical role in an musical production at the Metropolitan Opera in New York (1931).
Hollywood Work
When her parent was offered a deal by a film studio, after his success on Broadway, she moved with her parents to Hollywood, where Gene made around 300 films. After attending school in Beverly Hills, June started her career in films, mostly 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 latter, she is charming as a New Yorker at a household party, whose dance card is filled maliciously to stop Lockhart dancing with her brother.
More importantly, although she did not know it at the time, was Son of Lassie (1945). It was one of multiple sequels to the extremely successful Lassie Come Home (1943), in which another actress had played the female character who assists the canine to return to the owners. In the later film, Lockhart played the now adult character.
The affectionate way in which she handled both Lassie and her offspring, Laddie, hero of a wartime adventure in enemy-held Norway, was in the consideration of the producers when it came to selecting the Lassie TV series 13 years later.
Television and Stage Work
Although she was offered leading roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her movie career was stagnating and that television would be the answer. Before embarking in a new 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 significant run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a doctor and mother figure. She also featured frequently in TV westerns 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 recurring 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 host finds a stray collie, and in another sitcom in 1995 as the parent of a dining manager.
Later Roles and Achievements
Her final TV appearance came in 2021 as the voice of Alpha Control in an episode of a streaming service’s remake of Lost in Space. In the big screen version starring well-known actors (1998), she had a digital cameo as a school principal. She took joy in learning how much of an inspiration 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 representative brought her its Exceptional Public Achievement Medal.
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 younger 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 second marriage, to John Lindsay, an architect.
She is remembered by her children and four grandkids.
