Starting her career in films, June Lockhart, who died aged 100, achieved her greatest success after switching predominantly to the small screen. Having been offered few opportunities to shine in films from her debut as a child in 1938 until 1947, she thrived on television in many popular series, especially in Lassie.
Portraying 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 agriculturalist Paul Martin and the adoptive mother of young Timmy Martin, whose dog was the eponymous hero of the series.
Even with playing a housewife, Lockhart skillfully avoided being overshadowed by the brilliant dog. She characterized the program as “a fantasy 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 series, Lockhart commented: “In six chaste years of playing a rural spouse and parent, I was hardly ever permitted to kiss my on-screen husband on the face.”
Journey into Lost in Space
Lockhart went straight into a second hit, Lost in Space (1965-68), a partly comedic 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 researchers investigating distant planets. Lockhart had to spend the majority of her time deftly trying to survive visual effects. As the show progressed, the storyline became increasingly less about this interstellar family and more about the boy and his friendship with a mechanical being, and the timid antagonist Dr Zachary Smith.
Beginnings in Show Business
Lockhart’s movie 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 real-life parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canadian-born Gene were both performers in dozens of movies, as well as on stage, it was nearly certain that June, who was born in New York, would enter show business.
Her first stage 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).
Transition to Hollywood and Film Roles
When her father was offered a contract by a motion picture 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 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 schedule is filled 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 a young star had played the girl who assists the canine to escape to the owners. In the later film, Lockhart played the now grown-up version.
The loving way in which she interacted with 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 casting the Lassie TV series 13 years later.
TV and Stage Career
Although she was offered major roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her film career was getting her nowhere and that TV would be the answer. Before embarking in a new direction, she won acclaim on Broadway in For Love or Money (1947), a humorous play for which she won a Tony award as best newcomer.
A additional significant 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 busy workload persisted for the next 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 talkshow, where the presenter finds a lost collie, and in another sitcom in 1995 as the mother of a restaurant manager.
Final Roles and Contributions
Her last TV appearance came in 2021 as the voice 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 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 unpaid representative brought her its prestigious award.
Among her limited later feature films was the fantasy, Troll (1986) in which she played a witch, 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 doctor. In addition to Anne, they had a second daughter, June. That union ended in divorce, as did her second marriage, to John Lindsay, an designer.
She is remembered by her daughters and four grandkids.
