Launching her career in films, June Lockhart, who died aged 100, found her greatest success after switching largely to television. Having been offered few chances to shine in films from her debut as a youngster in 1938 until 1947, she thrived on TV in many popular series, especially in Lassie.
Her Memorable Role in Lassie
Taking over from another actress in 1958, Lockhart continued in the show until 1964. She played Ruth Martin, wed to agriculturalist Paul Martin and the foster mother of seven-year-old Timmy Martin, whose collie was the eponymous star of the series.
Despite playing a mother figure, Lockhart adeptly avoided being overshadowed by the smart animal star. She characterized the show as “a fairy tale about people on a rural property in which the dog resolves all the problems in 22 minutes, in time for the last commercial”. After she departed the show, Lockhart remarked: “In six sexless years of playing a country spouse and mother, I was rarely permitted to peck my co-star on the cheek.”
Journey into Lost in Space
Lockhart went directly into another successful series, Lost in Space (1965-68), a partly comedic sci-fi series targeted primarily at young audiences and inspired by The Swiss Family Robinson. Lockhart and another actor portrayed Maureen and John Robinson, two scientists investigating alien planets. Lockhart had to spend most of her time deftly trying to navigate 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 cowardly villain Dr Zachary Smith.
Start in Entertainment
Lockhart’s feature film first role, at the 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 actors in dozens of movies, as well as on theater, it was nearly certain that June, who was born in New York, would join show business.
Her first stage performance, at the age of six, came in a non-musical role in an opera at the Metropolitan Opera in New York (1931).
Cinema Work
When her parent was offered a deal by a film 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 professional life in movies, mainly 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 latter, she is charming as a New Yorker at a household party, whose schedule is filled maliciously to prevent Lockhart dancing with her sibling.
More importantly, although she did not realize it at the time, was Son of Lassie (1945). It was one of multiple follow-ups to the extremely successful Lassie Come Home (1943), in which a young star had played the girl who helps the canine to return to the family. In the subsequent film, Lockhart played the now adult character.
The affectionate way in which she interacted with both Lassie and her offspring, Laddie, hero of a wartime adventure in enemy-held Norway, was in the consideration of the producers when it came to selecting the Lassie TV series 13 years later.
TV and Stage Work
Although she was offered leading roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her movie career was getting her nowhere and that TV would be the solution. Before going in a new 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 further significant run came with Petticoat Junction (1968-70), set in a country 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 hectic schedule 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 stray collie, and in another sitcom in 1995 as the mother of a restaurant manager.
Final Career and Legacy
Her final TV credit came in 2021 as the narration of Alpha Control in an episode of a streaming service’s new version of Lost in Space. In the movie version featuring well-known actors (1998), she had a digital cameo as a school principal. She took pleasure in learning how much of an inspiration the first series had been to future astronauts, and often participated in the agency’s launches and other events. In 2013 her work as a unpaid representative brought her its prestigious award.
Among her limited later feature films was the fantasy, Troll (1986) in which she portrayed a sorceress, with her own daughter, Anne Lockhart, playing her younger self.
Personal Life and Family
In 1951 she married John Maloney, a physician and former Navy doctor. In addition to Anne, they had a second daughter, June. That marriage ended in divorce, as did her second marriage, to John Lindsay, an designer.
She is remembered by her children and four grandchildren.
