June Lockhart, who passed away at the remarkable age of 100, started her professional journey in films, but achieved fame after transitioning almost exclusively to television. Having been given limited chances to shine in films from her first appearance as a child in 1938 until 1947, she excelled on television in many beloved 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, married to agriculturalist Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose dog was the titular hero of the series.
In her part as a homemaker, Lockhart somehow managed to avoid being totally upstaged by the clever canine. She described the program as “a fairy tale 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 left the show, Lockhart remarked: “In six chaste years of playing a country spouse and mother, I was rarely permitted to kiss my co-star on the cheek.”
Starring in Lost in Space
Lockhart went directly into another successful series, Lost in Space (1965-68), a partly comedic sci-fi series targeted mostly at children and based by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two researchers exploring distant planets. Lockhart had to spend the majority of her time deftly trying to navigate visual effects. As the series progressed, the storyline became increasingly less about this space family and more about the young son 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 roles of her mother and father, Bob and Mrs Cratchit, were her real-life parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canada-native Gene were both performers in many of movies, as well as on theater, it was nearly inevitable that June, who was born in New York, would enter the entertainment industry.
Her first theatrical performance, at the 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 given a contract by a film studio, after his acclaim on Broadway, she relocated with her parents to Hollywood, where Gene made around 300 films. After attending school in Beverly Hills, June began her professional life in movies, mostly 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 arranged 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 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 owners. In the subsequent film, Lockhart played the now adult version.
The affectionate way in which she handled both Lassie and her offspring, Laddie, protagonist of a wartime story in enemy-held Norway, was in the consideration of the producers when it came to casting the Lassie TV series 13 years later.
Shift to Television and Stage Achievement
Although she was given major roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her film career was getting her nowhere and that television would be the solution. Before going 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 significant run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a doctor 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 hectic workload 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 lost collie, and in another sitcom in 1995 as the parent of a restaurant manager.
Later Career and Impact
Her final 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 big screen version featuring well-known actors (1998), she had a holographic cameo as a school principal. She took pleasure 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 volunteer spokesperson 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 medical officer. 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 daughters and four grandkids.
