Starting her career in films, June Lockhart, who passed on aged 100, found her greatest success after switching largely to television. Having been given limited opportunities to excel in films from her first appearance as a child in 1938 until 1947, she excelled on television in many popular series, especially in Lassie.
Her Iconic Role in Lassie
Stepping in from another actress in 1958, Lockhart remained in the series until 1964. Her role was Ruth Martin, married to farmer Paul Martin and the foster mother of seven-year-old Timmy Martin, whose dog was the titular hero of the series.
In her part as a housewife, Lockhart somehow succeeded to avoid being totally overshadowed by the clever dog. She characterized the program as “a fairy tale about families on a rural property in which the canine resolves all the problems in 22 minutes, in time for the last advertisement”. After she left the series, Lockhart remarked: “In six chaste years of playing a rural spouse and parent, I was hardly ever allowed to peck my on-screen husband on the cheek.”
Adventure into Lost in Space
Lockhart went straight into a second hit, Lost in Space (1965-68), a partly comedic science fiction series targeted primarily at children and based by The Swiss Family Robinson. Lockhart and her co-star portrayed Maureen and John Robinson, two scientists investigating alien planets. Lockhart had to spend the majority of her time skillfully trying to navigate visual effects. As the series progressed, the storyline became less and 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.
Initial Career and Family Background
Lockhart’s feature film first role, at the young 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 UK-native Kathleen and Canadian-born Gene were both performers in many of films, as well as on theater, it was almost inevitable that June, who was born in New York, would join show business.
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 parent was offered a contract by a film studio, after his acclaim on Broadway, she relocated with her parents to Hollywood, where Gene made around 300 films. After attending school in Beverly Hills, June began her professional life 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 spitefully to prevent 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 multiple follow-ups to the hugely successful Lassie Come Home (1943), in which another actress had played the female character who helps the canine to escape to the family. In the later film, Lockhart played the now grown-up version.
The loving way in which she handled both Lassie and her son, Laddie, protagonist of a wartime story in enemy-held Norway, was in the minds of the producers when it came to selecting the Lassie TV series 13 years later.
Shift to Television and Broadway Achievement
Although she was given major roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her film career was getting her nowhere and that TV would be the answer. Before embarking in a different direction, she received acclaim on Broadway in For Love or Money (1947), a comedy for which she won a Tony award as most promising newcomer.
A further substantial run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a doctor and maternal character. She also featured regularly in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic 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 talkshow, where the presenter finds a lost collie, and in another sitcom in 1995 as the parent of a dining manager.
Final Roles and Contributions
Her final TV appearance 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 movie version featuring well-known actors (1998), she had a digital cameo as a school principal. She took joy in learning how much of an inspiration the original series had been to later astronauts, and often participated in the agency’s launches and other events. In 2013 her work as a unpaid spokesperson brought her its Exceptional Public Achievement Medal.
Among her few later feature films was the fantasy, Troll (1986) in which she portrayed a sorceress, with her own daughter, Anne Lockhart, playing her younger self.
Personal Life and Family
In 1951 she wed John Maloney, a physician and former Navy medical officer. In addition to Anne, they had a second daughter, June. That marriage ended in divorce, as did her second marriage, to John Lindsay, an architect.
She is remembered by her children and four grandkids.
