June Lockhart, who passed away at the remarkable age of 100, began her career in films, but achieved recognition after transitioning almost entirely to television. Having been given few opportunities to excel in films from her debut as a child in 1938 until 1947, she excelled on TV in many popular series, especially in Lassie.
Becoming Ruth Martin on Lassie
Taking over from a previous star in 1958, Lockhart continued in the series until 1964. She played Ruth Martin, wed to farmer Paul Martin and the foster mother of seven-year-old Timmy Martin, whose dog was the titular star of the series.
In her part as a homemaker, Lockhart somehow succeeded to avoid being totally overshadowed by the clever dog. She characterized the program as “a fantasy about people on a rural property in which the dog resolves all the issues in 22 minutes, in time for the last advertisement”. After she departed the series, Lockhart remarked: “In six chaste years of playing a rural spouse and mother, I was hardly ever permitted to peck my on-screen husband on the cheek.”
Featuring in Lost in Space
Lockhart went straight into a second successful series, Lost in Space (1965-68), a semi-spoof science fiction series targeted mostly at children and based by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two scientists investigating distant planets. Lockhart had to spend most of her time skillfully trying to navigate special effects. As the series continued, the narrative became less and less about this space clan and more about the boy and his bond with a mechanical being, and the cowardly antagonist Dr Zachary Smith.
Start in Entertainment
Lockhart’s feature film 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 Canadian-born Gene were both performers in dozens 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 theatrical performance, at the tender age of six, came in a non-musical role in an opera at the Metropolitan Opera in New York (1931).
Cinema 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 approximately 300 films. After going to school in Beverly Hills, June started her professional life in films, 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 delightful as a New Yorker at a household party, whose dance card is filled spitefully to prevent Lockhart interacting with her sibling.
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 a young star had played the female character who assists the canine to escape to the family. In the subsequent film, Lockhart played the now grown-up character.
The affectionate way in which she interacted with both Lassie and her offspring, Laddie, protagonist of a wartime adventure in enemy-held Norway, was in the consideration of the producers when it came to casting the Lassie TV series 13 years later.
Television and Theater Career
Although she was offered major roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her movie career was stagnating and that TV 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 best newcomer.
A further significant run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a physician and maternal character. She also appeared regularly 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 comedy series, where the presenter finds a lost collie, and in another sitcom in 1995 as the parent of a dining manager.
Later Career and Legacy
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 holographic cameo as a school principal. She took joy in learning how much of an inspiration the first series had been to future astronauts, and often attended the organization’s launches and other events. In 2013 her work as a volunteer spokesperson 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 younger self.
Personal Life and Family
In 1951 she married John Maloney, a doctor and former Navy medical officer. 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 grandkids.
