June Lockhart, who died at the remarkable age of 100, started her career in films, but gained recognition after moving almost exclusively to TV. Having been given limited opportunities to shine in movies from her first appearance as a child in 1938 until 1947, she excelled on TV in numerous popular series, most notably in Lassie.
Becoming Ruth Martin on Lassie
Taking over from another actress in 1958, Lockhart remained in the show until 1964. She played Ruth Martin, wed to farmer Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose collie was the eponymous star of the series.
In her role as a housewife, Lockhart somehow succeeded to avoid being totally upstaged by the intelligent canine. She described the program as “a fantasy about people on a rural property in which the dog resolves all the problems in 22 minutes, in time for the last commercial”. After she departed the series, Lockhart remarked: “In six chaste years of playing a country wife and mother, I was rarely permitted to peck my co-star on the face.”
Starring in Lost in Space
Lockhart went straight into another hit, Lost in Space (1965-68), a semi-spoof science fiction series targeted primarily at children and based by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two scientists exploring alien planets. Lockhart had to spend the majority of her time skillfully trying to navigate special effects. As the show progressed, the storyline became increasingly less about this interstellar clan and more about the boy and his friendship with a mechanical being, and the cowardly villain Dr Zachary Smith.
Start in Entertainment
Lockhart’s feature film first role, 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 actual parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canada-native 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 the entertainment industry.
Her first stage performance, at the tender age of six, came in a non-singing role in an musical production at the Metropolitan Opera in New York (1931).
Hollywood Career
When her parent was offered a deal by a motion picture studio, after his success on Broadway, she relocated with her family to Hollywood, where Gene made around 300 films. After going to school in Beverly Hills, June began her career in films, mainly in small 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 family party, whose dance card is arranged spitefully to stop Lockhart dancing with her sibling.
More importantly, although she did not know 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 a young star had played the female character who assists the canine to return to the owners. In the later film, Lockhart played the now grown-up character.
The loving way in which she interacted with both Lassie and her son, Laddie, hero of a wartime adventure in enemy-held Norway, was in the minds of the producers when it came to casting the Lassie TV series 13 years later.
TV and Stage Career
Although she was given major roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her movie career was stagnating and that TV would be the solution. 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 best newcomer.
A additional significant run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a physician and mother figure. She also appeared frequently in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy workload 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 presenter finds a lost collie, and in another sitcom in 1995 as the parent of a dining manager.
Later Roles and Contributions
Her last TV credit 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 famous actors (1998), she had a digital cameo as a school principal. She took pleasure in learning how much of an influence the first series had been to later astronauts, and often attended the agency’s launches and other events. In 2013 her work as a volunteer representative brought her its prestigious award.
Among her few later 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 married 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 architect.
She is survived by her children and four grandchildren.
