Starting her career in films, June Lockhart, who died aged 100, achieved her greatest success after shifting largely to the small screen. Having been given limited opportunities to shine in films from her first appearance as a child in 1938 until 1947, she thrived on television in many popular series, especially in Lassie.
Her Memorable Role in Lassie
Taking over from a previous star in 1958, Lockhart continued in the show until 1964. Her role was Ruth Martin, married to agriculturalist Paul Martin and the adoptive mother of young Timmy Martin, whose dog was the eponymous star of the series.
Despite playing a mother figure, Lockhart adeptly avoided being overshadowed by the brilliant dog. She characterized the show as “a fantasy about families on a rural property in which the canine solves all the issues in 22 minutes, in time for the last advertisement”. After she left the series, Lockhart commented: “In six chaste years of playing a rural wife and parent, I was hardly ever allowed to peck my co-star on the face.”
Adventure into Lost in Space
Lockhart went directly into another hit, Lost in Space (1965-68), a semi-spoof sci-fi series aimed primarily at children and inspired by The Swiss Family Robinson. Lockhart and another actor portrayed Maureen and John Robinson, two researchers exploring alien planets. Lockhart had to spend most of her time skillfully trying to navigate special effects. As the show progressed, the narrative became less and less about this interstellar clan and more about the young son and his friendship with a robot, and the timid antagonist Dr Zachary Smith.
Initial Career and Family Influence
Lockhart’s feature film 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 Canadian-born Gene were both performers in many of films, as well as on theater, it was nearly certain that June, who was born in New York, would join show business.
Her first stage performance, at the age of six, came in a non-musical role in an opera at the Metropolitan Opera in New York (1931).
Move to Hollywood and Film Roles
When her parent was offered a deal by a film studio, after his success on Broadway, she moved with her family to Hollywood, where Gene made around 300 films. After attending school in Beverly Hills, June started her professional life 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 arranged spitefully to stop Lockhart dancing with her brother.
More significantly, 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 female character who helps the canine to escape to the owners. In the later film, Lockhart played the now adult character.
The loving way in which she handled both Lassie and her offspring, Laddie, protagonist of a World War II adventure in Nazi-occupied Norway, was in the consideration of the producers when it came to casting the Lassie TV series 13 years later.
TV and Stage Career
Although she was offered major roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her movie career was getting her nowhere and that TV would be the solution. Before going 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 maternal character. She also featured 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 next 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 presenter finds a stray collie, and in another sitcom in 1995 as the parent of a dining manager.
Later Roles and Contributions
Her last 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 starring famous 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 attended the organization’s launches and other events. In 2013 her work as a unpaid representative brought her its prestigious award.
Among her limited subsequent feature films was the fantasy, Troll (1986) in which she played 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 marriage ended in separation, as did her second marriage, to John Lindsay, an architect.
She is survived by her daughters and four grandkids.
