Launching her career in cinema, June Lockhart, who passed on aged 100, achieved her biggest success after shifting largely to the small screen. Having been given limited chances to excel in movies from her first appearance as a child in 1938 until 1947, she thrived on TV in numerous beloved series, especially in Lassie.
Portraying Ruth Martin on Lassie
Taking over from a previous star in 1958, Lockhart continued in the show until 1964. Her role was Ruth Martin, wed to farmer 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 managed to avoid being completely upstaged by the clever canine. She characterized the show as “a fairy tale about people on a farm in which the dog resolves all the issues in 22 minutes, in time for the last advertisement”. After she departed the show, Lockhart remarked: “In six chaste years of playing a country wife and parent, I was rarely permitted to peck my co-star on the face.”
Starring in Lost in Space
Lockhart went directly into another hit, Lost in Space (1965-68), a semi-spoof sci-fi series aimed primarily at young audiences and based by The Swiss Family Robinson. Lockhart and her co-star portrayed Maureen and John Robinson, two scientists investigating distant planets. Lockhart had to spend the majority of her time skillfully trying to survive visual effects. As the series continued, the storyline became increasingly less about this interstellar clan and increasingly about the young son and his bond with a mechanical being, and the timid antagonist Dr Zachary Smith.
Early 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 mother and father, Bob and Mrs Cratchit, were her actual parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canadian-born Gene were both performers in many of movies, as well as on theater, it was nearly inevitable 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 opera at the Metropolitan Opera in New York (1931).
Move to Hollywood and Movie Roles
When her parent was given a deal by a motion picture studio, after his acclaim on Broadway, she relocated with her parents to Hollywood, where Gene made approximately 300 films. After going to school in Beverly Hills, June started her professional life in films, mostly in minor 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 maliciously to stop Lockhart dancing with her brother.
More significantly, although she did not know it at the time, was Son of Lassie (1945). It was one of several sequels to the extremely successful Lassie Come Home (1943), in which another actress had played the girl who helps the dog to escape to the family. In the subsequent film, Lockhart played the now adult character.
The affectionate way in which she handled both Lassie and her son, Laddie, protagonist of a wartime adventure in enemy-held Norway, was in the consideration of the producers when it came to selecting the Lassie TV series 13 years later.
Transition to Television and Broadway Achievement
Although she was offered major roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her movie career was stagnating and that television would be the solution. Before embarking in a different direction, she received acclaim on Broadway in For Love or Money (1947), a comedy for which she won a Tony award as best newcomer.
A further substantial run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a physician and mother figure. She also featured frequently in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic schedule continued 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 host finds a stray collie, and in another sitcom in 1995 as the mother of a dining manager.
Later Roles and Achievements
Her final TV appearance came in 2021 as the voice of Alpha Control in an episode of a digital platform’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 later astronauts, and often attended the agency’s launches and other events. In 2013 her work as a unpaid spokesperson 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.
Private Details
In 1951 she married John Maloney, a doctor and former Navy doctor. In addition to Anne, they had a second daughter, June. That marriage ended in divorce, as did her second marriage, to John Lindsay, an designer.
She is remembered by her children and four grandchildren.
