Launching her career in films, June Lockhart, who passed on aged 100, achieved her greatest success after switching predominantly to the small screen. Having been given few opportunities to shine in movies from her debut as a child in 1938 until 1947, she thrived on television in many popular series, most notably in Lassie.
Her Iconic Role in Lassie
Taking over from another actress in 1958, Lockhart remained in the series until 1964. She played Ruth Martin, married to agriculturalist Paul Martin and the adoptive mother of young 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 canine. She described the program as “a fantasy about families on a farm in which the canine resolves all the problems in 22 minutes, in time for the last commercial”. After she left the series, Lockhart remarked: “In six chaste years of playing a rural wife and mother, I was hardly ever permitted to kiss my on-screen husband on the face.”
Featuring in Lost in Space
Lockhart went straight into a second hit, Lost in Space (1965-68), a partly comedic sci-fi series aimed primarily at children and based by The Swiss Family Robinson. Lockhart and her co-star played Maureen and John Robinson, two researchers exploring alien planets. Lockhart had to spend the majority of her time deftly trying to survive special effects. As the series progressed, the narrative became increasingly less about this interstellar family and increasingly about the boy and his bond with a robot, and the timid antagonist Dr Zachary Smith.
Beginnings in Show Business
Lockhart’s feature film debut, at the age of 13, had come as Belinda Cratchit in A Christmas Carol (1938). In the parts of her mother and father, Bob and Mrs Cratchit, were her real-life parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canada-native Gene were both performers in many of movies, as well as on stage, it was nearly certain that June, who was born in New York, would enter the entertainment industry.
Her first stage appearance, at the age of six, came in a non-singing role in an opera at the Metropolitan Opera in New York (1931).
Cinema Work
When her parent was given a deal by a motion picture 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 started her professional life in films, 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 spitefully to prevent Lockhart interacting with her brother.
More importantly, although she did not know it at the time, was Son of Lassie (1945). It was one of several sequels to the extremely successful Lassie Come Home (1943), in which another actress had played the girl who assists the dog to return to the owners. In the later film, Lockhart played the now grown-up version.
The loving way in which she interacted with both Lassie and her offspring, Laddie, protagonist of a wartime story in Nazi-occupied Norway, was in the consideration of the producers when it came to casting the Lassie TV series 13 years later.
Shift to Television and Stage Achievement
Although she was given leading roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her movie career was stagnating and that TV would be the answer. Before going in a different direction, she won acclaim on Broadway in For Love or Money (1947), a comedy 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 physician 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 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 talkshow, where the presenter finds a stray collie, and in another sitcom in 1995 as the mother of a dining manager.
Later Career and Legacy
Her last TV credit 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 starring famous actors (1998), she had a holographic cameo as a school principal. She took joy in learning how much of an inspiration the original series had been to future astronauts, and often attended the organization’s launches and other events. In 2013 her work as a unpaid spokesperson brought her its Exceptional Public Achievement Medal.
Among her few later feature films was the fantasy, Troll (1986) in which she played a sorceress, with her own daughter, Anne Lockhart, playing her earlier self.
Private Information
In 1951 she married John Maloney, a physician and former Navy medical officer. In addition to Anne, they had another daughter, June. That union ended in divorce, as did her subsequent marriage, to John Lindsay, an architect.
She is remembered by her children and four grandkids.
