Launching her career in cinema, June Lockhart, who died aged 100, found her biggest success after switching largely to the small screen. Having been given limited chances to shine in movies from her first appearance as a youngster in 1938 until 1947, she excelled on TV in numerous popular series, especially in Lassie.
Her Iconic Role in Lassie
Taking over from a previous star in 1958, Lockhart continued in the series until 1964. Her role was Ruth Martin, wed to agriculturalist Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose collie was the titular hero of the series.
Despite playing a housewife, Lockhart skillfully avoided being overshadowed by the brilliant animal star. She characterized the program as “a fantasy about people on a rural property in which the dog resolves all the issues in 22 minutes, in time for the last commercial”. After she departed the show, Lockhart remarked: “In six sexless years of playing a country spouse and parent, I was hardly ever permitted to kiss my on-screen husband on the cheek.”
Journey into Lost in Space
Lockhart went directly into another hit, Lost in Space (1965-68), a semi-spoof science fiction series aimed mostly at young audiences and inspired by The Swiss Family Robinson. Lockhart and another actor portrayed Maureen and John Robinson, two scientists investigating distant planets. Lockhart had to spend the majority of her time skillfully trying to navigate visual effects. As the series progressed, the narrative became less and less about this interstellar family and increasingly about the young son and his friendship with a robot, and the cowardly villain Dr Zachary Smith.
Beginnings in Show Business
Lockhart’s feature film first role, 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 British-born Kathleen and Canadian-born Gene were both actors in dozens of movies, as well as on stage, it was almost certain 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-singing role in an musical production at the Metropolitan Opera in New York (1931).
Hollywood Work
When her father was offered a deal by a film studio, after his acclaim on Broadway, she moved with her family 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 last one, she is delightful as a New Yorker at a family party, whose schedule is arranged spitefully to prevent Lockhart interacting with her sibling.
More significantly, although she did not know 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 a young star had played the female character who helps the dog to escape to the family. In the subsequent film, Lockhart played the now adult 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 casting the Lassie TV series 13 years later.
TV and Stage Work
Although she was given major roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her film career was stagnating and that television would be the answer. Before going in a new direction, she received praise on Broadway in For Love or Money (1947), a humorous play for which she won a Tony award as best newcomer.
A additional substantial run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a physician 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 workload persisted for the following five decades, with a regular role in General Hospital between 1984 and 1998. Among her many guest appearances were as the actress 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 dining manager.
Final Roles and Contributions
Her last TV credit 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 famous actors (1998), she had a digital cameo as a school principal. She took joy in learning how much of an influence the first series had been to future astronauts, and often attended the organization’s launches and other events. In 2013 her work as a volunteer spokesperson brought her its Exceptional Public Achievement Medal.
Among her limited subsequent feature films was the fantasy, Troll (1986) in which she played a sorceress, with her own daughter, Anne Lockhart, playing her earlier self.
Private Information
In 1951 she wed John Maloney, a physician and former Navy doctor. In addition to Anne, they had another daughter, June. That union ended in separation, as did her second marriage, to John Lindsay, an designer.
She is remembered by her children and four grandchildren.
