Launching her career in cinema, June Lockhart, who died aged 100, achieved her biggest success after switching largely to television. Having been offered limited opportunities to excel in films from her debut as a youngster in 1938 until 1947, she thrived on television in numerous beloved series, most notably in Lassie.
Her Memorable 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 young Timmy Martin, whose collie was the eponymous hero of the series.
In her role as a homemaker, Lockhart somehow managed to avoid being completely upstaged by the clever dog. She described the show as “a fairy tale about people on a farm in which the canine solves all the problems in 22 minutes, in time for the last commercial”. After she left the series, Lockhart remarked: “In six sexless years of playing a rural wife and parent, I was rarely allowed to peck my on-screen husband on the cheek.”
Featuring in Lost in Space
Lockhart went straight into another hit, Lost in Space (1965-68), a semi-spoof sci-fi series targeted mostly at children and inspired by The Swiss Family Robinson. Lockhart and her co-star portrayed Maureen and John Robinson, two scientists investigating distant planets. Lockhart had to spend the majority of her time deftly trying to navigate special effects. As the show continued, the storyline became less and less about this space clan and more about the boy and his friendship with a robot, and the timid villain Dr Zachary Smith.
Beginnings in Show Business
Lockhart’s feature film debut, at the young age of 13, had come as Belinda Cratchit in A Christmas Carol (1938). In the roles of her parents, Bob and Mrs Cratchit, were her actual parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canadian-born Gene were both performers in dozens 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 tender age of six, came in a non-musical role in an musical production at the Metropolitan Opera in New York (1931).
Move to Hollywood and Film Roles
When her father was offered a contract by a film studio, after his success on Broadway, she moved with her parents to Hollywood, where Gene made around 300 films. After going to school in Beverly Hills, June began her career in movies, 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 filled spitefully to prevent Lockhart interacting with her brother.
More significantly, although she did not know it at the time, was Son of Lassie (1945). It was one of multiple follow-ups to the extremely successful Lassie Come Home (1943), in which another actress had played the girl who assists the dog to escape to the family. In the subsequent film, Lockhart played the now adult version.
The affectionate way in which she handled both Lassie and her son, Laddie, hero of a World War II adventure in Nazi-occupied Norway, was in the minds of the creators when it came to casting the Lassie TV series 13 years later.
Shift to Television and Stage Success
Although she was given 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 going in a new direction, she received 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 mother figure. She also appeared regularly in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy workload persisted for the next 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 stray collie, and in another sitcom in 1995 as the parent of a restaurant manager.
Final Career and Legacy
Her last TV appearance came in 2021 as the voice of Alpha Control in an episode of a digital platform’s remake of Lost in Space. In the movie version featuring well-known actors (1998), she had a holographic cameo as a school principal. She took pleasure in learning how much of an influence the first series had been to future astronauts, and often attended the agency’s launches and other events. In 2013 her work as a volunteer representative 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 wed John Maloney, a physician and former Navy medical officer. In addition to Anne, they had another daughter, June. That marriage ended in separation, as did her subsequent marriage, to John Lindsay, an architect.
She is survived by her children and four grandkids.
