June Lockhart, who passed away at the remarkable age of 100, started her career in films, but gained fame after moving almost exclusively to television. Having been given limited chances to shine in movies from her first appearance as a youngster in 1938 until 1947, she thrived on television in numerous popular series, most notably in Lassie.
Her Iconic Role in Lassie
Taking over from a previous star in 1958, Lockhart remained in the show until 1964. She played Ruth Martin, wed to farmer Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose dog was the eponymous star of the series.
Despite playing a mother figure, Lockhart adeptly avoided being outshone by the smart dog. She described the show 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 commercial”. After she departed the show, Lockhart commented: “In six chaste years of playing a country spouse and parent, I was rarely allowed to kiss my co-star on the face.”
Journey into Lost in Space
Lockhart went straight into another hit, Lost in Space (1965-68), a partly comedic science fiction series aimed primarily at children and inspired by The Swiss Family Robinson. Lockhart and her co-star portrayed Maureen and John Robinson, two researchers investigating alien planets. Lockhart had to spend the majority of her time deftly trying to navigate visual effects. As the show continued, the narrative became increasingly less about this space family and increasingly about the boy and his bond with a mechanical being, and the cowardly villain Dr Zachary Smith.
Beginnings 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 roles of her parents, 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 films, as well as on theater, it was almost inevitable that June, who was born in New York, would enter show business.
Her first theatrical appearance, at the tender age of six, came in a non-musical role in an opera at the Metropolitan Opera in New York (1931).
Transition to Hollywood and Film Roles
When her parent was offered a deal by a motion picture studio, after his success on Broadway, she moved with her family to Hollywood, where Gene made around 300 films. After attending school in Beverly Hills, June started her professional life 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 delightful as a New Yorker at a family party, whose schedule is arranged spitefully to prevent Lockhart dancing with her sibling.
More significantly, although she did not know it at the time, was Son of Lassie (1945). It was one of multiple follow-ups to the hugely successful Lassie Come Home (1943), in which a young star had played the female character who helps the dog to escape to the family. In the later film, Lockhart played the now grown-up version.
The loving way in which she interacted with both Lassie and her son, Laddie, hero of a World War II story in Nazi-occupied Norway, was in the consideration of the producers 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 decided her film career was stagnating and that television 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 rural hotel, where Lockhart is a physician and mother figure. 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 persisted for the next five decades, with a regular 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 host finds a lost collie, and in another sitcom in 1995 as the mother of a restaurant manager.
Final Roles and Contributions
Her final TV appearance came in 2021 as the voice of Alpha Control in an episode of a streaming service’s new version of Lost in Space. In the movie version starring famous actors (1998), she had a holographic 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 attended the agency’s launches and other events. In 2013 her work as a unpaid representative brought her its Exceptional Public Achievement Medal.
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 Life and Family
In 1951 she married John Maloney, a doctor and former Navy medical officer. In addition to Anne, they had a second daughter, June. That union ended in separation, as did her second marriage, to John Lindsay, an designer.
She is remembered by her children and four grandkids.
