Starting her career in films, June Lockhart, who passed on aged 100, found her biggest success after shifting predominantly to television. Having been offered limited chances to shine in movies from her first appearance as a youngster in 1938 until 1947, she excelled on television in numerous beloved series, especially in Lassie.
Becoming Ruth Martin on Lassie
Taking over from a previous star in 1958, Lockhart remained in the series until 1964. She played Ruth Martin, wed to farmer Paul Martin and the foster mother of seven-year-old Timmy Martin, whose dog was the eponymous hero of the series.
In her role as a homemaker, Lockhart somehow managed to avoid being completely overshadowed by the intelligent dog. She characterized the show as “a fairy tale about people on a farm in which the dog resolves all the problems in 22 minutes, in time for the last commercial”. After she departed the show, Lockhart commented: “In six chaste years of playing a country wife and parent, I was hardly ever permitted to kiss my co-star on the face.”
Featuring in Lost in Space
Lockhart went straight into another hit, Lost in Space (1965-68), a semi-spoof science fiction series targeted primarily at young audiences and based by The Swiss Family Robinson. Lockhart and another actor portrayed Maureen and John Robinson, two researchers investigating distant planets. Lockhart had to spend most of her time deftly trying to navigate visual effects. As the show continued, the narrative became less and less about this interstellar clan and increasingly about the young son and his friendship with a robot, and the cowardly antagonist 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 parts of her parents, 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 theater, it was nearly inevitable that June, who was born in New York, would enter the entertainment industry.
Her first theatrical performance, at the tender age of six, came in a non-musical role in an opera at the Metropolitan Opera in New York (1931).
Move to Hollywood and Movie Roles
When her parent was offered a deal by a motion picture studio, after his success on Broadway, she relocated with her family to Hollywood, where Gene made approximately 300 films. After attending school in Beverly Hills, June began her career in films, mostly in minor roles in prestigious 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 delightful as a New Yorker at a household party, whose dance card is arranged spitefully to prevent Lockhart dancing with her brother.
More importantly, 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 a young star had played the girl who helps the canine to escape to the family. In the later film, Lockhart played the now grown-up character.
The loving way in which she interacted with both Lassie and her offspring, Laddie, protagonist of a World War II adventure in enemy-held Norway, was in the minds of the creators when it came to casting the Lassie TV series 13 years later.
Shift to Television and Broadway Achievement
Although she was given leading roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her film career was getting her nowhere and that TV would be the answer. 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 most promising newcomer.
A additional substantial run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a doctor 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 hectic 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 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.
Later Career and Impact
Her last 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 big screen version starring famous actors (1998), she had a digital cameo as a school principal. She took pleasure in learning how much of an influence the original series had been to later astronauts, and often participated in the organization’s launches and other events. In 2013 her work as a unpaid spokesperson brought her its prestigious award.
Among her few subsequent feature films was the fantasy, Troll (1986) in which she played a witch, 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 union ended in divorce, as did her second marriage, to John Lindsay, an designer.
She is survived by her children and four grandchildren.
