June Lockhart, who passed away at the remarkable age of 100, began her career in films, but achieved recognition after transitioning almost exclusively to TV. Having been offered few chances to shine in movies from her first appearance as a child in 1938 until 1947, she thrived on TV in numerous beloved series, most notably in Lassie.
Becoming Ruth Martin on Lassie
Stepping in from another actress in 1958, Lockhart continued in the show until 1964. She played Ruth Martin, married to farmer Paul Martin and the foster mother of seven-year-old Timmy Martin, whose dog was the eponymous hero of the series.
In her part as a housewife, Lockhart somehow succeeded to avoid being completely overshadowed by the clever canine. She characterized the show as “a fantasy about people on a farm in which the dog solves all the problems in 22 minutes, in time for the last commercial”. After she departed the show, Lockhart remarked: “In six chaste years of playing a rural spouse and mother, I was hardly ever allowed to kiss my on-screen husband on the cheek.”
Journey into Lost in Space
Lockhart went directly into another successful series, Lost in Space (1965-68), a partly comedic science fiction series aimed primarily at young audiences and inspired by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two scientists exploring alien planets. Lockhart had to spend most of her time deftly trying to survive visual effects. As the series continued, the storyline became increasingly less about this interstellar family and increasingly about the boy and his bond with a mechanical being, and the timid villain 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 UK-native Kathleen and Canadian-born 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 appearance, at the tender age of six, came in a non-singing role in an opera at the Metropolitan Opera in New York (1931).
Transition to Hollywood and Film Roles
When her father was offered a deal by a motion picture studio, after his acclaim on Broadway, she moved with her parents to Hollywood, where Gene made around 300 films. After going to school in Beverly Hills, June began her career 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 last one, she is delightful as a New Yorker at a household party, whose dance card is filled maliciously to stop Lockhart interacting with her brother.
More significantly, although she did not know 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 girl who assists the canine to return to the owners. In the subsequent film, Lockhart played the now grown-up character.
The loving way in which she interacted with both Lassie and her son, Laddie, hero of a wartime adventure in Nazi-occupied Norway, was in the minds of the creators when it came to selecting the Lassie TV series 13 years later.
TV and Theater Work
Although she was offered major roles in two thrillers, 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 embarking in a different direction, she received praise on Broadway in For Love or Money (1947), a comedy for which she won a Tony award as best 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 regularly in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy schedule continued for the next five decades, with a regular role in General Hospital between 1984 and 1998. Among her many guest 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 restaurant manager.
Final Roles and Contributions
Her last TV credit came in 2021 as the narration of Alpha Control in an episode of a streaming service’s remake of Lost in Space. In the movie version featuring famous actors (1998), she had a digital cameo as a school principal. She took pleasure in learning how much of an influence the original series had been to future astronauts, and often participated in the agency’s launches and other events. In 2013 her work as a volunteer representative brought her its prestigious award.
Among her few subsequent feature films was the fantasy, Troll (1986) in which she played a sorceress, with her own daughter, Anne Lockhart, playing her earlier self.
Personal Information
In 1951 she wed John Maloney, a physician and former Navy doctor. In addition to Anne, they had a second daughter, June. That union ended in divorce, as did her second marriage, to John Lindsay, an designer.
She is remembered by her children and four grandchildren.
