June Lockhart, who died at the age of 100, began her career in movies, but achieved fame after moving almost exclusively to television. Having been offered limited opportunities to excel in movies from her debut as a child in 1938 until 1947, she excelled on TV in many beloved series, most notably in Lassie.
Her Memorable Role in Lassie
Stepping in from a previous star in 1958, Lockhart remained in the show until 1964. Her role was Ruth Martin, married to agriculturalist Paul Martin and the foster mother of seven-year-old Timmy Martin, whose dog was the titular star of the series.
Despite playing a housewife, Lockhart adeptly avoided being overshadowed by the brilliant dog. She described the show as “a fantasy about families on a rural property in which the dog solves all the problems in 22 minutes, in time for the last advertisement”. After she departed the series, Lockhart commented: “In six chaste years of playing a country wife and parent, I was hardly ever allowed to kiss my co-star on the cheek.”
Adventure into Lost in Space
Lockhart went directly into another hit, 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 researchers investigating alien planets. Lockhart had to spend most of her time deftly trying to navigate special effects. As the show continued, the narrative became increasingly less about this interstellar family and increasingly about the young son and his friendship with a mechanical being, and the cowardly villain 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 real-life parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canada-native Gene were both performers in many of movies, as well as on stage, it was almost inevitable that June, who was born in New York, would join show business.
Her first theatrical performance, at the tender age of six, came in a non-singing role in an musical production at the Metropolitan Opera in New York (1931).
Transition to Hollywood and Film Roles
When her father was given a contract by a film studio, after his acclaim on Broadway, she moved with her family to Hollywood, where Gene made around 300 films. After going to school in Beverly Hills, June started her career in movies, mainly in small 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 charming as a New Yorker at a family party, whose schedule is filled maliciously to stop Lockhart interacting with her brother.
More importantly, although she did not know it at the time, was Son of Lassie (1945). It was one of several follow-ups to the extremely 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 grown-up version.
The loving way in which she interacted with both Lassie and her offspring, Laddie, hero of a World War II adventure in Nazi-occupied Norway, was in the minds of the creators when it came to casting the Lassie TV series 13 years later.
TV and Stage Career
Although she was given leading roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her film career was getting her nowhere and that TV 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 most promising newcomer.
A additional substantial run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a doctor and mother figure. She also featured regularly in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy workload 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 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 restaurant 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 new version of Lost in Space. In the big screen version starring well-known 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 participated in the organization’s launches and other events. In 2013 her work as a unpaid representative brought her its Exceptional Public Achievement Medal.
Among her limited subsequent feature films was the fantasy, Troll (1986) in which she portrayed a sorceress, with her own daughter, Anne Lockhart, playing her earlier self.
Personal Details
In 1951 she wed John Maloney, a physician and former Navy doctor. 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 daughters and four grandkids.
