Launching her career in cinema, June Lockhart, who passed on aged 100, found her greatest success after switching predominantly to television. Having been offered limited opportunities to shine in movies from her debut as a youngster in 1938 until 1947, she thrived on TV in many beloved series, most notably in Lassie.
Portraying Ruth Martin on Lassie
Stepping in from another actress in 1958, Lockhart remained in the show until 1964. Her role was Ruth Martin, wed to agriculturalist Paul Martin and the foster mother of young Timmy Martin, whose dog was the titular star of the series.
In her part as a homemaker, Lockhart somehow managed to avoid being totally overshadowed by the intelligent canine. She characterized the show as “a fantasy about people on a farm in which the canine solves all the issues in 22 minutes, in time for the last commercial”. After she left the series, Lockhart commented: “In six chaste years of playing a country wife and mother, I was hardly ever permitted 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 inspired by The Swiss Family Robinson. Lockhart and her co-star portrayed 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 show progressed, the storyline became increasingly less about this space family and more about the boy and his bond with a mechanical being, and the cowardly villain Dr Zachary Smith.
Start in Show Business
Lockhart’s feature film first role, 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 Canada-native Gene were both actors in dozens of films, as well as on stage, it was nearly inevitable that June, who was born in New York, would join show business.
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 Film Roles
When her parent was given a contract by a motion picture studio, after his acclaim on Broadway, she relocated with her family to Hollywood, where Gene made approximately 300 films. After attending school in Beverly Hills, June started her career in films, 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 last one, she is charming as a New Yorker at a household party, whose schedule is filled maliciously to stop Lockhart dancing with her sibling.
More importantly, although she did not realize it at the time, was Son of Lassie (1945). It was one of multiple sequels to the hugely successful Lassie Come Home (1943), in which a young star had played the girl who assists the dog to return to the family. In the later film, Lockhart played the now adult character.
The affectionate way in which she handled both Lassie and her offspring, Laddie, protagonist of a wartime adventure in enemy-held Norway, was in the consideration of the producers when it came to casting the Lassie TV series 13 years later.
TV and Theater Career
Although she was offered leading roles in two suspense films, 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 embarking in a different 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 additional significant run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a physician and maternal character. She also featured frequently in TV westerns 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 regular 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 lost collie, and in another sitcom in 1995 as the parent of a restaurant manager.
Final Roles and Contributions
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 movie version featuring well-known actors (1998), she had a holographic cameo as a school principal. She took joy in learning how much of an inspiration the original series had been to future astronauts, and often attended the agency’s launches and other events. In 2013 her work as a volunteer spokesperson brought her its prestigious award.
Among her few later feature films was the fantasy, Troll (1986) in which she played a sorceress, with her own daughter, Anne Lockhart, playing her earlier self.
Personal Information
In 1951 she married John Maloney, a physician and former Navy doctor. In addition to Anne, they had another daughter, June. That marriage ended in separation, as did her subsequent marriage, to John Lindsay, an designer.
She is remembered by her children and four grandkids.
