June Lockhart, who died at the age of 100, began her career in movies, but achieved recognition after transitioning almost entirely to television. Having been given few opportunities to shine in films from her first appearance as a youngster in 1938 until 1947, she thrived on TV in numerous beloved series, especially in Lassie.
Portraying Ruth Martin on Lassie
Stepping in from a previous star in 1958, Lockhart continued in the show until 1964. She played Ruth Martin, married to farmer Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose dog was the eponymous hero of the series.
In her role as a housewife, Lockhart somehow succeeded to avoid being completely upstaged by the intelligent canine. She characterized the program as “a fairy tale about people on a farm in which the dog resolves all the problems in 22 minutes, in time for the last commercial”. After she left the show, Lockhart commented: “In six chaste years of playing a country wife and mother, I was hardly ever allowed to kiss my on-screen husband on the cheek.”
Featuring in Lost in Space
Lockhart went directly into another hit, Lost in Space (1965-68), a partly comedic science fiction series targeted mostly at young audiences and based by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two scientists exploring distant planets. Lockhart had to spend the majority of her time skillfully trying to navigate special effects. As the series continued, the narrative became increasingly less about this space clan and more about the boy and his bond with a mechanical being, and the timid villain Dr Zachary Smith.
Early Career and Family Influence
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 real-life parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canada-native Gene were both actors in many of movies, as well as on theater, it was almost inevitable that June, who was born in New York, would join show business.
Her first stage performance, at the tender age of six, came in a non-musical role in an opera at the Metropolitan Opera in New York (1931).
Hollywood Work
When her parent was offered a contract by a film studio, after his acclaim on Broadway, she moved with her parents to Hollywood, where Gene made approximately 300 films. After going to school in Beverly Hills, June began her professional life in films, mainly 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 household party, whose schedule is filled maliciously to prevent Lockhart interacting with her brother.
More importantly, although she did not realize it at the time, was Son of Lassie (1945). It was one of multiple sequels to the hugely successful Lassie Come Home (1943), in which another actress had played the female character who assists the canine to return 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, hero of a World War II story in Nazi-occupied Norway, was in the minds of the producers when it came to casting the Lassie TV series 13 years later.
Transition to Television and Broadway Success
Although she was given 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 answer. Before going in a new direction, she won praise on Broadway in For Love or Money (1947), a comedy for which she won a Tony award as best 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 frequently in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic schedule continued for the next five decades, with a recurring role in General Hospital between 1984 and 1998. Among her many guest appearances were as the actress in a 1988 episode of a comedy series, where the presenter finds a lost collie, and in another sitcom in 1995 as the mother of a dining manager.
Later Roles and Achievements
Her final TV credit came in 2021 as the narration 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 volunteer spokesperson brought her its Exceptional Public Achievement Medal.
Among her few later feature films was the fantasy, Troll (1986) in which she played a sorceress, with her own daughter, Anne Lockhart, playing her younger self.
Personal Life and Family
In 1951 she married John Maloney, a doctor and former Navy doctor. In addition to Anne, they had another daughter, June. That marriage ended in separation, as did her second marriage, to John Lindsay, an designer.
She is remembered by her daughters and four grandkids.
