June Lockhart, who died at the remarkable age of 100, began her career in films, but gained fame after moving almost exclusively to TV. Having been given limited chances to shine in films from her first appearance as a youngster in 1938 until 1947, she thrived on TV in many beloved series, most notably in Lassie.
Her Iconic Role in Lassie
Stepping in from another actress in 1958, Lockhart remained 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 titular star of the series.
In her role as a housewife, Lockhart somehow managed to avoid being totally upstaged by the intelligent canine. She described the show as “a fairy tale about people on a farm in which the canine solves all the issues in 22 minutes, in time for the last commercial”. After she departed the series, Lockhart remarked: “In six sexless years of playing a rural spouse and parent, I was rarely allowed to peck my co-star on the cheek.”
Journey into Lost in Space
Lockhart went straight into a second hit, Lost in Space (1965-68), a semi-spoof science fiction series targeted primarily at young audiences and based by The Swiss Family Robinson. Lockhart and her co-star portrayed Maureen and John Robinson, two researchers investigating distant planets. Lockhart had to spend the majority of her time skillfully trying to navigate special effects. As the series continued, the storyline became less and less about this interstellar family and increasingly about the boy and his friendship with a robot, and the cowardly antagonist Dr Zachary Smith.
Initial Career and Family Background
Lockhart’s movie debut, 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 UK-native Kathleen and Canada-native Gene were both actors in many of films, as well as on theater, it was almost inevitable that June, who was born in New York, would enter the entertainment industry.
Her first stage performance, at the age of six, came in a non-musical role in an opera at the Metropolitan Opera in New York (1931).
Hollywood Career
When her father was given a deal by a motion picture studio, after his success on Broadway, she moved with her family to Hollywood, where Gene made approximately 300 films. After attending school in Beverly Hills, June began her professional life in movies, mainly 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 last one, she is charming as a New Yorker at a family party, whose schedule is arranged spitefully to prevent Lockhart dancing 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 another actress had played the girl who helps the canine to return to the family. In the subsequent film, Lockhart played the now grown-up version.
The affectionate way in which she handled both Lassie and her son, Laddie, hero of a wartime story in enemy-held Norway, was in the minds of the creators when it came to selecting the Lassie TV series 13 years later.
Transition to Television and Broadway Achievement
Although she was offered leading roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her movie career was getting her nowhere and that television would be the solution. Before going in a different direction, she won praise on Broadway in For Love or Money (1947), a comedy for which she won a Tony award as most promising newcomer.
A further substantial run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a physician and mother figure. She also appeared regularly in TV westerns 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 recurring role in General Hospital between 1984 and 1998. Among her many one-off appearances were as herself in a 1988 episode of a comedy series, where the presenter finds a lost collie, and in another sitcom in 1995 as the parent of a restaurant 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 new version 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 inspiration the original series had been to later astronauts, and often attended 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 witch, with her own daughter, Anne Lockhart, playing her younger self.
Personal Details
In 1951 she wed John Maloney, a physician and former Navy medical officer. In addition to Anne, they had a second daughter, June. That marriage ended in separation, as did her second marriage, to John Lindsay, an designer.
She is remembered by her children and four grandkids.
