June Lockhart, who died at the age of 100, began her career in films, but gained recognition after moving almost exclusively to TV. Having been offered few opportunities to shine in movies from her debut as a youngster in 1938 until 1947, she excelled on TV in numerous beloved series, most notably in Lassie.
Portraying Ruth Martin on Lassie
Stepping in from a previous star in 1958, Lockhart remained in the series until 1964. Her role was Ruth Martin, married to agriculturalist Paul Martin and the adoptive mother of young Timmy Martin, whose dog was the titular hero of the series.
Despite playing a housewife, Lockhart adeptly avoided being outshone by the smart animal star. She described the program as “a fairy tale about families on a farm in which the canine resolves all the issues in 22 minutes, in time for the last commercial”. After she departed the show, Lockhart commented: “In six chaste years of playing a rural spouse and mother, I was rarely permitted to peck my co-star on the cheek.”
Starring in Lost in Space
Lockhart went directly into another hit, Lost in Space (1965-68), a semi-spoof science fiction series targeted primarily at children and inspired 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 survive visual effects. As the series continued, the storyline became less and less about this space family and increasingly about the young son and his bond with a robot, and the cowardly villain Dr Zachary Smith.
Beginnings in Show Business
Lockhart’s movie debut, at the age of 13, had come as Belinda Cratchit in A Christmas Carol (1938). In the parts of her parents, 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 stage, it was almost inevitable that June, who was born in New York, would join the entertainment industry.
Her first stage appearance, at the age of six, came in a non-musical role in an opera at the Metropolitan Opera in New York (1931).
Transition to Hollywood and Film Roles
When her father was given a deal by a film studio, after his success on Broadway, she moved with her parents to Hollywood, where Gene made approximately 300 films. After going to 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 dance card is arranged spitefully to stop Lockhart interacting with her sibling.
More significantly, although she did not realize it at the time, was Son of Lassie (1945). It was one of several follow-ups to the extremely successful Lassie Come Home (1943), in which a young star had played the girl who helps the canine to return to the owners. In the later film, Lockhart played the now adult version.
The loving way in which she interacted with both Lassie and her son, Laddie, hero of a wartime adventure in Nazi-occupied Norway, was in the minds of the producers when it came to selecting the Lassie TV series 13 years later.
Transition to Television and Stage Achievement
Although she was offered leading roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her movie career was getting her nowhere and that television would be the answer. Before going 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 most promising newcomer.
A additional substantial run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a physician 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 continued for the next five decades, with a recurring role in General Hospital between 1984 and 1998. Among her many guest 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 parent of a restaurant manager.
Later Career and Legacy
Her last TV credit came in 2021 as the voice of Alpha Control in an episode of a streaming service’s new version of Lost in Space. In the big screen version featuring well-known actors (1998), she had a holographic 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 participated in the organization’s launches and other events. In 2013 her work as a unpaid representative brought her its prestigious award.
Among her few later feature films was the fantasy, Troll (1986) in which she portrayed a witch, with her own daughter, Anne Lockhart, playing her earlier self.
Personal Life and Family
In 1951 she wed John Maloney, a doctor and former Navy doctor. In addition to Anne, they had a second daughter, June. That union ended in divorce, as did her second marriage, to John Lindsay, an architect.
She is survived by her children and four grandchildren.
