Launching her career in cinema, June Lockhart, who died aged 100, found her greatest success after switching predominantly to the small screen. Having been offered few chances to excel in movies from her debut as a youngster in 1938 until 1947, she thrived on TV in numerous popular series, most notably in Lassie.
Her Memorable Role in Lassie
Stepping in from a previous star 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 collie was the titular hero of the series.
In her role as a homemaker, Lockhart somehow managed to avoid being completely upstaged by the clever canine. She characterized the show as “a fairy tale about people on a rural property in which the dog solves all the issues in 22 minutes, in time for the last commercial”. After she departed the series, Lockhart commented: “In six sexless years of playing a country wife and mother, I was rarely permitted to peck my co-star on the face.”
Adventure into Lost in Space
Lockhart went directly into a second successful series, Lost in Space (1965-68), a semi-spoof science fiction series targeted primarily at children and inspired by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two scientists investigating distant planets. Lockhart had to spend the majority of her time skillfully trying to survive special effects. As the series continued, the storyline became less and less about this space family and increasingly about the boy and his friendship with a mechanical being, and the cowardly villain Dr Zachary Smith.
Start in Entertainment
Lockhart’s feature film debut, at the 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 Canadian-born Gene were both actors in dozens of films, 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 age of six, came in a non-singing role in an opera at the Metropolitan Opera in New York (1931).
Move to Hollywood and Film Roles
When her parent was offered a contract by a motion picture studio, after his acclaim on Broadway, she relocated with her family to Hollywood, where Gene made around 300 films. After going to school in Beverly Hills, June started her career in films, mostly 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 household party, whose dance card is arranged spitefully to stop Lockhart dancing with her sibling.
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 extremely successful Lassie Come Home (1943), in which another actress had played the female character who helps the canine to escape to the owners. In the subsequent film, Lockhart played the now adult character.
The affectionate way in which she handled both Lassie and her son, Laddie, hero of a wartime adventure in Nazi-occupied Norway, was in the minds of the producers when it came to selecting the Lassie TV series 13 years later.
TV and Stage Work
Although she was given leading roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her film career was stagnating and that TV would be the solution. Before embarking in a new direction, she won praise on Broadway in For Love or Money (1947), a comedy for which she won a Tony award as best newcomer.
A additional substantial run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a doctor and maternal character. She also appeared frequently in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy workload persisted for the following five decades, with a recurring role in General Hospital between 1984 and 1998. Among her many guest appearances were as the actress 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 dining manager.
Final Career and Legacy
Her final 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 starring famous 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 representative brought her its prestigious award.
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 Details
In 1951 she married John Maloney, a doctor and former Navy doctor. In addition to Anne, they had a second 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.
