June Lockhart, who died at the age of 100, began her professional journey in movies, but achieved fame after moving almost entirely to TV. Having been given few opportunities to excel in movies from her first appearance as a child in 1938 until 1947, she excelled on TV in numerous beloved series, especially in Lassie.
Her Memorable Role in Lassie
Stepping in from a previous star in 1958, Lockhart remained in the series until 1964. She played Ruth Martin, wed to agriculturalist Paul Martin and the foster mother of young Timmy Martin, whose collie was the eponymous hero of the series.
In her part as a homemaker, Lockhart somehow succeeded to avoid being completely overshadowed by the intelligent dog. She described the show as “a fantasy about families 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 rural spouse and parent, I was rarely permitted to peck my co-star on the cheek.”
Starring in Lost in Space
Lockhart went straight into a second successful series, Lost in Space (1965-68), a semi-spoof sci-fi series targeted primarily at young audiences and based by The Swiss Family Robinson. Lockhart and her co-star played Maureen and John Robinson, two scientists exploring distant planets. Lockhart had to spend most of her time skillfully trying to navigate special effects. As the show progressed, the storyline became less and less about this interstellar family and more about the young son and his friendship with a mechanical being, and the timid villain Dr Zachary Smith.
Beginnings in Show Business
Lockhart’s movie first role, at the young age of 13, had come as Belinda Cratchit in A Christmas Carol (1938). In the roles 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 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 stage appearance, at the age of six, came in a non-musical role in an musical production at the Metropolitan Opera in New York (1931).
Cinema Work
When her parent was given a contract by a motion picture studio, after his acclaim on Broadway, she relocated with her family to Hollywood, where Gene made around 300 films. After going to school in Beverly Hills, June began her career in movies, 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 latter, she is charming as a New Yorker at a household party, whose dance card is filled maliciously to prevent Lockhart interacting with her brother.
More importantly, although she did not know it at the time, was Son of Lassie (1945). It was one of multiple follow-ups to the extremely successful Lassie Come Home (1943), in which another actress had played the girl who assists the dog to return to the family. In the later film, Lockhart played the now grown-up version.
The affectionate way in which she handled both Lassie and her son, Laddie, protagonist of a World War II story in enemy-held Norway, was in the consideration of the producers when it came to casting the Lassie TV series 13 years later.
TV and Stage Work
Although she was offered major roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her movie career was stagnating and that TV would be the answer. Before embarking 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 further 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 schedule persisted for the following 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 presenter finds a lost collie, and in another sitcom in 1995 as the mother of a dining manager.
Final Roles and Achievements
Her final 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 featuring famous actors (1998), she had a digital cameo as a school principal. She took pleasure in learning how much of an inspiration the first series had been to later 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 few later feature films was the fantasy, Troll (1986) in which she portrayed 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 medical officer. In addition to Anne, they had a second daughter, June. That union ended in divorce, as did her subsequent marriage, to John Lindsay, an architect.
She is survived by her daughters and four grandchildren.
