June Lockhart, who passed away at the age of 100, started her career in movies, but gained recognition after moving almost exclusively to TV. Having been offered limited chances to shine in movies from her first appearance as a child in 1938 until 1947, she thrived on television in many popular series, most notably in Lassie.
Portraying Ruth Martin on Lassie
Stepping in 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.
In her part as a housewife, Lockhart somehow succeeded to avoid being completely overshadowed by the clever dog. She characterized the program as “a fantasy about people on a rural property in which the canine solves all the issues in 22 minutes, in time for the last advertisement”. After she departed the series, Lockhart remarked: “In six chaste years of playing a rural spouse and parent, I was rarely allowed to peck my on-screen husband on the cheek.”
Adventure into Lost in Space
Lockhart went directly into a second successful series, Lost in Space (1965-68), a semi-spoof science fiction series aimed 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 most of her time deftly trying to navigate special effects. As the series continued, the narrative became increasingly 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.
Start 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 mother and father, Bob and Mrs Cratchit, were her real-life parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canadian-born Gene were both performers in dozens of movies, as well as on stage, it was almost 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 opera at the Metropolitan Opera in New York (1931).
Transition to Hollywood and Movie Roles
When her parent was given a contract by a film studio, after his success on Broadway, she relocated 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 latter, she is delightful as a New Yorker at a family party, whose dance card is arranged spitefully to stop 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 multiple follow-ups to the hugely successful Lassie Come Home (1943), in which another actress had played the girl who assists the canine to escape to the family. In the subsequent film, Lockhart played the now adult version.
The loving way in which she interacted with both Lassie and her offspring, Laddie, hero of a wartime adventure in Nazi-occupied Norway, was in the consideration of the producers when it came to selecting the Lassie TV series 13 years later.
Transition to Television and Stage Success
Although she was offered major roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her movie career was getting her nowhere and that television would be the solution. Before going in a new direction, she won acclaim on Broadway in For Love or Money (1947), a comedy for which she won a Tony award as best newcomer.
A further significant run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a doctor and maternal character. She also appeared regularly in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy schedule persisted for the following 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 host finds a stray collie, and in another sitcom in 1995 as the mother of a dining manager.
Final Roles and Achievements
Her final TV credit 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 holographic cameo as a school principal. She took pleasure in learning how much of an inspiration the first series had been to later astronauts, and often participated in the organization’s launches and other events. In 2013 her work as a unpaid representative brought her its Exceptional Public Achievement Medal.
Among her limited later feature films was the fantasy, Troll (1986) in which she played a witch, with her own daughter, Anne Lockhart, playing her younger self.
Private Details
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 subsequent marriage, to John Lindsay, an designer.
She is remembered by her children and four grandkids.
