Launching her career in cinema, June Lockhart, who passed on aged 100, found her greatest success after shifting predominantly to the small screen. Having been offered few opportunities to excel in movies from her first appearance as a youngster in 1938 until 1947, she excelled on TV in many popular series, most notably in Lassie.
Becoming Ruth Martin on Lassie
Taking over from a previous star in 1958, Lockhart remained in the show until 1964. She played Ruth Martin, married to agriculturalist Paul Martin and the adoptive mother of young Timmy Martin, whose dog was the eponymous star of the series.
In her part as a housewife, Lockhart somehow managed to avoid being totally upstaged by the clever dog. She described the program as “a fantasy about families on a farm in which the dog solves all the problems in 22 minutes, in time for the last advertisement”. After she departed the show, Lockhart remarked: “In six sexless years of playing a country spouse and parent, I was rarely allowed to kiss my co-star on the cheek.”
Adventure into Lost in Space
Lockhart went straight into another hit, Lost in Space (1965-68), a partly comedic sci-fi series aimed primarily at children and inspired by The Swiss Family Robinson. Lockhart and another actor portrayed Maureen and John Robinson, two researchers investigating alien planets. Lockhart had to spend most of her time skillfully trying to survive special effects. As the series continued, the narrative became increasingly less about this interstellar clan and increasingly about the young son and his friendship with a robot, and the cowardly antagonist Dr Zachary Smith.
Early Career and Family Influence
Lockhart’s movie debut, 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 Canadian-born 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 show business.
Her first stage appearance, at the tender age of six, came in a non-singing role in an opera at the Metropolitan Opera in New York (1931).
Move 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 professional life in films, mainly in minor 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 family party, whose dance card 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 assists the canine to return to the owners. In the later film, Lockhart played the now adult version.
The affectionate way in which she interacted with both Lassie and her offspring, Laddie, protagonist of a World War II adventure in enemy-held Norway, was in the minds of the producers when it came to selecting the Lassie TV series 13 years later.
Shift to Television and Stage Success
Although she was given leading roles in two suspense films, 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 solution. Before embarking in a different direction, she won 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 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 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 stray collie, and in another sitcom in 1995 as the mother of a restaurant manager.
Later Roles and Contributions
Her final TV credit came in 2021 as the voice of Alpha Control in an episode of a digital platform’s remake of Lost in Space. In the movie version starring 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 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 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 separation, as did her second marriage, to John Lindsay, an designer.
She is survived by her daughters and four grandkids.
