June Lockhart, who passed away at the remarkable age of 100, started her professional journey in films, but achieved recognition after moving almost exclusively to TV. Having been given few chances to excel in films from her debut as a child in 1938 until 1947, she thrived on TV in many popular series, especially in Lassie.
Becoming Ruth Martin on Lassie
Stepping in from another actress in 1958, Lockhart continued in the show until 1964. Her role was Ruth Martin, married to agriculturalist Paul Martin and the foster mother of young Timmy Martin, whose collie was the eponymous star of the series.
Despite playing a housewife, Lockhart skillfully avoided being overshadowed by the smart dog. She characterized the program as “a fantasy about people on a farm in which the dog solves all the issues in 22 minutes, in time for the last commercial”. After she left the series, Lockhart remarked: “In six sexless years of playing a country wife and mother, I was hardly ever permitted to kiss my co-star on the face.”
Featuring in Lost in Space
Lockhart went directly into another hit, Lost in Space (1965-68), a semi-spoof sci-fi series targeted primarily at children and based by The Swiss Family Robinson. Lockhart and her co-star played Maureen and John Robinson, two researchers investigating alien planets. Lockhart had to spend the majority of her time skillfully trying to navigate special effects. As the series progressed, the storyline became increasingly less about this space clan and increasingly about the boy and his friendship with a robot, and the timid antagonist Dr Zachary Smith.
Start in Show Business
Lockhart’s feature film first role, 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 Canada-native Gene were both performers in dozens of films, as well as on stage, it was nearly certain that June, who was born in New York, would enter the entertainment industry.
Her first stage appearance, at the age of six, came in a non-singing role in an opera at the Metropolitan Opera in New York (1931).
Hollywood Work
When her parent was given a deal by a film studio, after his acclaim on Broadway, she relocated with her family to Hollywood, where Gene made approximately 300 films. After attending school in Beverly Hills, June began her professional life in movies, mostly in small roles in acclaimed 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 dance card is arranged maliciously 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 a young star had played the girl who helps the canine to return to the owners. In the later film, Lockhart played the now adult character.
The affectionate way in which she handled both Lassie and her offspring, Laddie, hero of a wartime story in Nazi-occupied Norway, was in the consideration of the producers when it came to selecting the Lassie TV series 13 years later.
Television and Stage Work
Although she was given major roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her film career was stagnating and that television would be the answer. Before embarking in a different direction, she won praise on Broadway in For Love or Money (1947), a humorous play for which she won a Tony award as best newcomer.
A further significant run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a physician and maternal character. She also appeared frequently in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic workload continued for the next five decades, with a recurring 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 presenter finds a stray collie, and in another sitcom in 1995 as the parent of a dining manager.
Final Career and Legacy
Her final 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 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 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 Details
In 1951 she married John Maloney, a doctor and former Navy medical officer. In addition to Anne, they had a second daughter, June. That union ended in divorce, as did her second marriage, to John Lindsay, an architect.
She is survived by her children and four grandchildren.
