June Lockhart: A Century of Television Success from Lassie to Lost in Space
Starting her career in films, June Lockhart, who died aged 100, achieved her biggest success after shifting predominantly to television. Having been given few opportunities to shine in films from her debut as a youngster in 1938 until 1947, she thrived on television in many popular series, most notably in Lassie.
Her Iconic Role in Lassie
Stepping in 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 skillfully avoided being outshone by the smart dog. She described the program as “a fantasy about families on a farm in which the canine solves all the issues in 22 minutes, in time for the last advertisement”. After she left the series, Lockhart remarked: “In six sexless years of playing a rural wife and parent, I was rarely permitted to peck my co-star on the face.”
Starring in Lost in Space
Lockhart went directly into another hit, Lost in Space (1965-68), a semi-spoof science fiction series targeted mostly at children and inspired by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two researchers investigating distant planets. Lockhart had to spend the majority of her time skillfully trying to navigate special effects. As the show progressed, the narrative became less and less about this interstellar clan and increasingly about the young son and his friendship with a robot, and the cowardly villain Dr Zachary Smith.
Early Career and Family Background
Lockhart’s movie 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 UK-native Kathleen and Canadian-born Gene were both actors in dozens of films, as well as on theater, it was nearly 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).
Hollywood Career
When her father was offered a deal by a film studio, after his acclaim on Broadway, she relocated with her parents to Hollywood, where Gene made around 300 films. After going to school in Beverly Hills, June began her career in films, 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 dance card is filled maliciously to prevent Lockhart interacting with her brother.
More significantly, although she did not know it at the time, was Son of Lassie (1945). It was one of several follow-ups to the hugely successful Lassie Come Home (1943), in which a young star had played the female character who assists the dog to escape to the family. In the subsequent film, Lockhart played the now grown-up character.
The affectionate way in which she handled both Lassie and her offspring, Laddie, hero of a World War II adventure in Nazi-occupied Norway, was in the minds of the creators when it came to casting the Lassie TV series 13 years later.
TV and Theater Work
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 stagnating and that television would be the solution. Before going in a new direction, she received acclaim on Broadway in For Love or Money (1947), a comedy for which she won a Tony award as most promising newcomer.
A additional substantial 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 busy workload continued for the following 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 presenter finds a lost collie, and in another sitcom in 1995 as the mother of a dining manager.
Final Roles and Achievements
Her final TV credit came in 2021 as the voice of Alpha Control in an episode of a streaming service’s remake of Lost in Space. In the big screen version starring well-known actors (1998), she had a digital cameo as a school principal. She took joy in learning how much of an inspiration 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 later feature films was the fantasy, Troll (1986) in which she portrayed a witch, with her own daughter, Anne Lockhart, playing her earlier self.
Private Information
In 1951 she wed John Maloney, a doctor and former Navy medical officer. In addition to Anne, they had another daughter, June. That union ended in separation, as did her second marriage, to John Lindsay, an architect.
She is remembered by her daughters and four grandkids.
