Launching her career in films, June Lockhart, who passed on aged 100, achieved her biggest success after shifting predominantly to the small screen. Having been given limited opportunities to shine in movies from her first appearance as a child in 1938 until 1947, she thrived on television in many beloved series, most notably in Lassie.
Her Memorable Role in Lassie
Stepping in from another actress in 1958, Lockhart remained in the show until 1964. Her role was Ruth Martin, wed to farmer Paul Martin and the foster mother of seven-year-old Timmy Martin, whose dog was the titular hero of the series.
In her part as a housewife, Lockhart somehow succeeded to avoid being totally overshadowed by the clever dog. She described the show as “a fantasy about families on a farm in which the canine resolves all the issues in 22 minutes, in time for the last advertisement”. After she departed the show, Lockhart remarked: “In six sexless years of playing a country wife and mother, I was hardly ever permitted to kiss my on-screen husband on the face.”
Journey into Lost in Space
Lockhart went straight into another hit, Lost in Space (1965-68), a partly comedic science fiction series targeted mostly at young audiences and based by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two scientists exploring distant planets. Lockhart had to spend the majority of her time deftly trying to survive visual effects. As the series progressed, the narrative became less and less about this interstellar clan and increasingly about the young son and his bond with a mechanical being, and the cowardly villain Dr Zachary Smith.
Initial Career and Family Influence
Lockhart’s movie debut, 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 actual parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canada-native Gene were both performers in dozens of films, as well as on theater, it was nearly certain that June, who was born in New York, would enter the entertainment industry.
Her first theatrical appearance, at the age of six, came in a non-singing role in an opera at the Metropolitan Opera in New York (1931).
Transition to Hollywood and Film Roles
When her parent was offered a deal by a film studio, after his acclaim on Broadway, she relocated with her parents to Hollywood, where Gene made approximately 300 films. After attending school in Beverly Hills, June began her career in films, mainly 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 charming 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 realize it at the time, was Son of Lassie (1945). It was one of several sequels to the hugely successful Lassie Come Home (1943), in which another actress had played the female character who helps the dog to return to the owners. In the subsequent film, Lockhart played the now adult version.
The affectionate way in which she handled both Lassie and her offspring, Laddie, protagonist of a wartime story in Nazi-occupied Norway, was in the minds of the creators when it came to selecting the Lassie TV series 13 years later.
Transition to Television and Broadway Success
Although she was given major roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her movie career was stagnating and that television would be the solution. Before embarking in a different 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 further substantial run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a doctor and maternal character. She also appeared frequently in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic workload persisted for the following five decades, with a recurring role in General Hospital between 1984 and 1998. Among her many guest appearances were as herself in a 1988 episode of a talkshow, where the host finds a stray collie, and in another sitcom in 1995 as the parent of a dining manager.
Final Career and Impact
Her final TV appearance came in 2021 as the narration of Alpha Control in an episode of a digital platform’s new version of Lost in Space. In the big screen version featuring well-known 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 future astronauts, and often attended the organization’s launches and other events. In 2013 her work as a volunteer spokesperson brought her its prestigious award.
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 younger self.
Personal Life and Family
In 1951 she wed John Maloney, a physician and former Navy doctor. In addition to Anne, they had a second daughter, June. That marriage ended in separation, as did her subsequent marriage, to John Lindsay, an designer.
She is remembered by her daughters and four grandchildren.
