Launching her career in cinema, June Lockhart, who died aged 100, achieved her greatest success after shifting largely to the small screen. Having been given few chances to excel in movies from her debut as a youngster in 1938 until 1947, she excelled on TV in many beloved series, most notably in Lassie.
Her Iconic Role in Lassie
Taking over from another actress in 1958, Lockhart continued in the show until 1964. Her role was Ruth Martin, wed to agriculturalist Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose dog was the eponymous hero of the series.
Even with playing a housewife, Lockhart skillfully avoided being overshadowed by the brilliant animal star. She described the show as “a fairy tale about people on a rural property in which the dog resolves all the issues in 22 minutes, in time for the last advertisement”. After she left the series, Lockhart commented: “In six sexless years of playing a rural wife and parent, I was hardly ever allowed to kiss my on-screen husband on the cheek.”
Adventure into 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 another actor played Maureen and John Robinson, two scientists investigating alien planets. Lockhart had to spend most of her time skillfully trying to survive visual effects. As the series progressed, the narrative became less and less about this interstellar family and increasingly about the young son and his friendship with a mechanical being, and the timid villain Dr Zachary Smith.
Early Career and Family Influence
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 parents, Bob and Mrs Cratchit, were her actual parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canada-native Gene were both performers in many of movies, as well as on stage, it was nearly inevitable that June, who was born in New York, would enter the entertainment industry.
Her first theatrical appearance, at the tender age of six, came in a non-musical role in an musical production at the Metropolitan Opera in New York (1931).
Move to Hollywood and Movie Roles
When her parent was given a deal by a motion picture studio, after his acclaim on Broadway, she relocated with her parents to Hollywood, where Gene made around 300 films. After going to school in Beverly Hills, June began her career in movies, 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 delightful as a New Yorker at a family party, whose schedule is arranged spitefully to stop Lockhart dancing with her sibling.
More significantly, although she did not know 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 canine to escape to the owners. In the later film, Lockhart played the now adult character.
The affectionate way in which she interacted with both Lassie and her offspring, Laddie, hero of a wartime adventure in Nazi-occupied Norway, was in the minds of the creators when it came to selecting the Lassie TV series 13 years later.
TV and Theater Career
Although she was offered leading roles in two thrillers, 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 answer. Before embarking in a new direction, she received praise on Broadway in For Love or Money (1947), a comedy for which she won a Tony award as most promising newcomer.
A additional significant run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a doctor 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 hectic 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 presenter finds a stray collie, and in another sitcom in 1995 as the mother of a dining manager.
Final Career and Legacy
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 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 first 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 prestigious award.
Among her few subsequent feature films was the fantasy, Troll (1986) in which she portrayed a witch, 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 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 architect.
She is survived by her children and four grandkids.
