Starting her career in cinema, June Lockhart, who passed on aged 100, found her biggest success after shifting predominantly to the small screen. Having been offered few opportunities to shine in movies from her debut as a child in 1938 until 1947, she excelled on TV in many beloved series, most notably in Lassie.
Her Iconic Role in Lassie
Taking over from another actress in 1958, Lockhart remained in the series until 1964. She played Ruth Martin, wed to agriculturalist Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose dog was the titular star of the series.
Despite playing a housewife, Lockhart skillfully avoided being outshone by the brilliant dog. She characterized the program as “a fantasy about people on a farm in which the dog resolves all the issues in 22 minutes, in time for the last advertisement”. After she left the show, Lockhart remarked: “In six sexless years of playing a country wife and parent, I was rarely permitted to kiss my on-screen husband on the face.”
Adventure into Lost in Space
Lockhart went directly into a second hit, Lost in Space (1965-68), a semi-spoof science fiction series aimed mostly at young audiences and based by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two researchers exploring alien planets. Lockhart had to spend most of her time skillfully trying to survive visual effects. As the show continued, the narrative became increasingly less about this space clan and more about the boy and his friendship with a mechanical being, and the timid villain Dr Zachary Smith.
Initial Career and Family Background
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 parents, 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 theater, it was almost certain that June, who was born in New York, would join the entertainment industry.
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).
Cinema Work
When her father was given a deal by a film studio, after his success on Broadway, she relocated with her family to Hollywood, where Gene made approximately 300 films. After going to school in Beverly Hills, June began her professional life in films, mostly 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 household party, whose schedule is filled spitefully to stop Lockhart dancing with her brother.
More importantly, although she did not realize it at the time, was Son of Lassie (1945). It was one of several sequels to the hugely successful Lassie Come Home (1943), in which another actress had played the girl who assists the canine to escape to the owners. In the later film, Lockhart played the now grown-up character.
The affectionate way in which she handled both Lassie and her son, Laddie, protagonist of a World War II adventure 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 Theater Work
Although she was offered major 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 television would be the answer. Before going in a new direction, she won acclaim on Broadway in For Love or Money (1947), a humorous play for which she won a Tony award as best newcomer.
A additional significant run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a physician and mother figure. She also appeared frequently in TV cowboy shows 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 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 stray collie, and in another sitcom in 1995 as the mother of a restaurant manager.
Later Roles and Achievements
Her last TV credit 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 well-known actors (1998), she had a holographic cameo as a school principal. She took joy in learning how much of an influence the original series had been to later astronauts, and often participated in the organization’s launches and other events. In 2013 her work as a volunteer spokesperson brought her its Exceptional Public Achievement Medal.
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 earlier self.
Personal Details
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.
