Launching her career in cinema, June Lockhart, who passed on aged 100, achieved her biggest success after switching predominantly to television. Having been given limited opportunities to excel in films from her debut as a youngster in 1938 until 1947, she thrived on television in many popular series, especially in Lassie.
Portraying Ruth Martin on Lassie
Taking over from another actress in 1958, Lockhart continued in the show until 1964. She played Ruth Martin, wed to agriculturalist Paul Martin and the adoptive mother of young Timmy Martin, whose dog was the titular star of the series.
In her role as a housewife, Lockhart somehow managed to avoid being completely overshadowed by the clever canine. She characterized the program as “a fairy tale about people on a farm in which the dog solves all the problems in 22 minutes, in time for the last advertisement”. After she departed the show, Lockhart remarked: “In six sexless years of playing a country wife and parent, I was hardly ever permitted to peck my on-screen husband on the cheek.”
Featuring in Lost in Space
Lockhart went directly into a second successful series, Lost in Space (1965-68), a semi-spoof science fiction series aimed mostly at children and based by The Swiss Family Robinson. Lockhart and her co-star played Maureen and John Robinson, two researchers exploring distant planets. Lockhart had to spend the majority of her time skillfully trying to survive special effects. As the series progressed, the storyline became increasingly less about this space clan and increasingly about the boy and his bond with a mechanical being, and the timid antagonist Dr Zachary Smith.
Early Career and Family Influence
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 mother and father, Bob and Mrs Cratchit, were her actual parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canada-native Gene were both actors in many of films, as well as on stage, it was almost inevitable that June, who was born in New York, would join the entertainment industry.
Her first theatrical appearance, at the age of six, came in a non-musical role in an opera at the Metropolitan Opera in New York (1931).
Hollywood Career
When her father was given a deal by a film studio, after his success on Broadway, she moved with her family to Hollywood, where Gene made around 300 films. After going to school in Beverly Hills, June started her career in films, mainly 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 family party, whose dance card is filled spitefully to prevent Lockhart interacting with her sibling.
More importantly, although she did not realize it at the time, was Son of Lassie (1945). It was one of multiple sequels to the extremely successful Lassie Come Home (1943), in which another actress had played the girl who assists the canine to return to the family. In the subsequent film, Lockhart played the now grown-up version.
The loving way in which she handled both Lassie and her offspring, Laddie, hero of a World War II story in enemy-held Norway, was in the minds of the creators when it came to selecting the Lassie TV series 13 years later.
Shift to Television and Broadway Achievement
Although she was offered 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 solution. Before embarking in a different direction, she won acclaim on Broadway in For Love or Money (1947), a humorous play 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 doctor and mother figure. She also appeared frequently in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic schedule continued for the next five decades, with a regular role in General Hospital between 1984 and 1998. Among her many one-off appearances were as the actress in a 1988 episode of a talkshow, where the host finds a lost collie, and in another sitcom in 1995 as the mother of a dining manager.
Final Roles and Contributions
Her last TV credit came in 2021 as the narration of Alpha Control in an episode of a streaming service’s remake 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 inspiration the original series had been to future astronauts, and often participated in the organization’s launches and other events. In 2013 her work as a unpaid 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 earlier 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 designer.
She is remembered by her children and four grandkids.
