Launching her career in films, June Lockhart, who passed on aged 100, found her biggest success after switching predominantly to television. Having been offered few chances to excel in movies from her first appearance as a child in 1938 until 1947, she excelled on TV in numerous popular series, especially in Lassie.
Becoming Ruth Martin on Lassie
Stepping in from another actress in 1958, Lockhart remained in the series until 1964. She played Ruth Martin, wed to farmer Paul Martin and the adoptive mother of young Timmy Martin, whose dog was the titular star of the series.
In her part as a homemaker, Lockhart somehow succeeded to avoid being completely overshadowed by the intelligent canine. She described the program as “a fantasy about families on a farm in which the dog resolves all the issues in 22 minutes, in time for the last advertisement”. After she left the show, Lockhart remarked: “In six sexless years of playing a rural spouse and mother, I was rarely allowed to peck 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 aimed mostly at young audiences and inspired by The Swiss Family Robinson. Lockhart and her co-star portrayed Maureen and John Robinson, two scientists exploring distant planets. Lockhart had to spend the majority of her time skillfully trying to navigate visual effects. As the series progressed, the narrative became increasingly less about this interstellar family and more about the boy and his friendship with a robot, and the timid antagonist Dr Zachary Smith.
Beginnings 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 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 many of movies, as well as on stage, it was nearly inevitable that June, who was born in New York, would join show business.
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 Career
When her parent was given a deal by a motion picture studio, after his acclaim on Broadway, she relocated with her family to Hollywood, where Gene made around 300 films. After attending school in Beverly Hills, June started 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 charming as a New Yorker at a household party, whose dance card is filled spitefully to prevent Lockhart interacting with her sibling.
More significantly, although she did not realize it at the time, was Son of Lassie (1945). It was one of several sequels to the hugely successful Lassie Come Home (1943), in which a young star had played the girl who helps the canine to escape 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 minds of the producers when it came to selecting the Lassie TV series 13 years later.
Shift to Television and Broadway Achievement
Although she was given leading roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her movie career was getting her nowhere and that television would be the solution. Before embarking in a new direction, she received acclaim on Broadway in For Love or Money (1947), a humorous play for which she won a Tony award as most promising newcomer.
A additional substantial run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a physician and maternal character. She also featured frequently in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic workload continued for the following 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 parent of a restaurant manager.
Later Career and Legacy
Her final TV credit came in 2021 as the voice of Alpha Control in an episode of a digital platform’s new version of Lost in Space. In the movie version starring famous actors (1998), she had a holographic cameo as a school principal. She took pleasure in learning how much of an influence the first series had been to later astronauts, and often participated in the organization’s launches and other events. In 2013 her work as a volunteer representative brought her its prestigious award.
Among her few 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 doctor and former Navy doctor. In addition to Anne, they had another daughter, June. That marriage ended in divorce, as did her second marriage, to John Lindsay, an architect.
She is remembered by her children and four grandchildren.
