Launching her career in films, June Lockhart, who died aged 100, achieved her greatest success after shifting largely to the small screen. Having been offered few opportunities to shine in movies from her debut as a child in 1938 until 1947, she thrived on TV in numerous beloved series, especially in Lassie.
Her Iconic Role in Lassie
Stepping in from a previous star in 1958, Lockhart continued in the series until 1964. Her role was Ruth Martin, wed to farmer Paul Martin and the foster mother of young Timmy Martin, whose collie was the eponymous hero of the series.
In her role as a housewife, Lockhart somehow succeeded to avoid being totally overshadowed by the intelligent dog. She characterized the show as “a fantasy about families on a farm in which the canine resolves all the issues in 22 minutes, in time for the last commercial”. After she left the show, Lockhart remarked: “In six sexless years of playing a country wife and mother, I was hardly ever allowed to peck my co-star on the face.”
Featuring in Lost in Space
Lockhart went directly into a second hit, Lost in Space (1965-68), a partly comedic science fiction series aimed primarily at children and based 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 deftly trying to survive visual effects. As the series continued, the narrative became less and less about this space family and increasingly about the boy and his friendship with a robot, and the timid antagonist Dr Zachary Smith.
Start in Show Business
Lockhart’s movie first role, 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 actual parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canada-native Gene were both performers in many of films, as well as on theater, it was almost certain that June, who was born in New York, would enter the entertainment industry.
Her first stage performance, at the tender age of six, came in a non-musical role in an opera at the Metropolitan Opera in New York (1931).
Cinema Career
When her parent was given a contract by a motion picture studio, after his success on Broadway, she relocated with her parents to Hollywood, where Gene made approximately 300 films. After attending school in Beverly Hills, June began her career in films, mainly in small roles in prestigious 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 schedule is arranged maliciously to stop Lockhart interacting with her brother.
More importantly, although she did not know it at the time, was Son of Lassie (1945). It was one of several follow-ups to the hugely successful Lassie Come Home (1943), in which another actress had played the female character who helps the canine to return to the family. In the later film, Lockhart played the now grown-up character.
The affectionate way in which she interacted with both Lassie and her son, Laddie, protagonist of a World War II 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 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 TV would be the answer. Before going in a new direction, she received 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 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 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 herself in a 1988 episode of a comedy series, where the host finds a lost collie, and in another sitcom in 1995 as the mother of a restaurant manager.
Final Roles and Achievements
Her final TV credit came in 2021 as the narration of Alpha Control in an episode of a streaming service’s new version of Lost in Space. In the big screen version starring famous actors (1998), she had a holographic cameo as a school principal. She took joy in learning how much of an inspiration the first series had been to future astronauts, and often attended 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 sorceress, with her own daughter, Anne Lockhart, playing her younger self.
Private Information
In 1951 she wed John Maloney, a physician 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 remembered by her children and four grandchildren.
