Starting her career in films, June Lockhart, who passed on aged 100, found her biggest success after switching predominantly to the small screen. Having been offered few chances to excel in movies from her first appearance as a child in 1938 until 1947, she excelled on television in numerous beloved series, especially in Lassie.
Her Iconic Role in Lassie
Taking over from another actress in 1958, Lockhart continued in the series until 1964. Her role was Ruth Martin, wed to farmer Paul Martin and the foster mother of seven-year-old Timmy Martin, whose collie was the eponymous star of the series.
Even with playing a housewife, Lockhart adeptly avoided being overshadowed by the smart dog. She characterized the show as “a fairy tale about families on a farm in which the canine solves all the issues in 22 minutes, in time for the last advertisement”. After she left the series, Lockhart commented: “In six sexless years of playing a country wife and mother, I was hardly ever permitted to kiss my co-star on the cheek.”
Adventure into Lost in Space
Lockhart went directly into another successful series, Lost in Space (1965-68), a partly comedic science fiction series aimed mostly at children and based by The Swiss Family Robinson. Lockhart and another actor portrayed Maureen and John Robinson, two scientists exploring alien planets. Lockhart had to spend most of her time deftly trying to navigate special effects. As the series progressed, the narrative became less and less about this interstellar clan and increasingly about the boy and his friendship with a mechanical being, and the timid antagonist Dr Zachary Smith.
Beginnings in Entertainment
Lockhart’s feature film debut, at the 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 British-born Kathleen and Canada-native Gene were both performers in many of films, as well as on stage, it was nearly 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-musical role in an opera at the Metropolitan Opera in New York (1931).
Move to Hollywood and Film Roles
When her parent was given a contract 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 began her career in films, mostly in small 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 dance card is filled spitefully to prevent 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 follow-ups to the extremely successful Lassie Come Home (1943), in which another actress had played the girl who helps the dog to return to the family. In the subsequent film, Lockhart played the now adult character.
The loving way in which she handled both Lassie and her son, Laddie, protagonist of a wartime story in Nazi-occupied Norway, was in the consideration of the creators when it came to selecting the Lassie TV series 13 years later.
TV and Stage Career
Although she was offered major 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 TV would be the answer. Before embarking in a new direction, she won praise on Broadway in For Love or Money (1947), a humorous play 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 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 next 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 talkshow, where the presenter finds a stray collie, and in another sitcom in 1995 as the mother of a dining manager.
Final Roles and Achievements
Her final TV appearance 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 featuring famous actors (1998), she had a digital cameo as a school principal. She took joy in learning how much of an influence the first series had been to future astronauts, and often attended the organization’s launches and other events. In 2013 her work as a unpaid spokesperson brought her its Exceptional Public Achievement Medal.
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 earlier self.
Private Information
In 1951 she wed John Maloney, a physician and former Navy medical officer. In addition to Anne, they had a second daughter, June. That marriage ended in divorce, as did her subsequent marriage, to John Lindsay, an designer.
She is remembered by her children and four grandchildren.
