June Lockhart, who died at the remarkable age of 100, started her professional journey in films, but gained fame after moving almost entirely to television. Having been offered limited chances to excel in movies from her first appearance as a child in 1938 until 1947, she thrived on television in many popular series, especially in Lassie.
Her Memorable Role in Lassie
Stepping in from a previous star in 1958, Lockhart continued in the series until 1964. She played Ruth Martin, wed to farmer Paul Martin and the adoptive mother of young Timmy Martin, whose collie was the eponymous star of the series.
In her part as a homemaker, Lockhart somehow succeeded to avoid being completely upstaged by the intelligent canine. She described the show as “a fantasy about people on a farm in which the dog solves all the issues in 22 minutes, in time for the last commercial”. After she departed the show, Lockhart remarked: “In six chaste years of playing a rural spouse and mother, I was rarely permitted to kiss my co-star on the face.”
Starring in Lost in Space
Lockhart went straight into a second hit, Lost in Space (1965-68), a partly comedic sci-fi series targeted primarily at children and inspired by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two scientists exploring distant planets. Lockhart had to spend the majority of her time deftly trying to survive visual effects. As the series continued, the narrative became less and less about this space clan and more about the boy and his friendship with a mechanical being, and the timid villain Dr Zachary Smith.
Beginnings in Show Business
Lockhart’s movie debut, at the age of 13, had come as Belinda Cratchit in A Christmas Carol (1938). In the parts of her parents, Bob and Mrs Cratchit, were her actual parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canadian-born Gene were both performers in dozens of films, as well as on theater, it was almost certain that June, who was born in New York, would enter show business.
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 Movie Roles
When her father was given a contract by a motion picture studio, after his acclaim on Broadway, she relocated 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 prestigious pictures such as Sergeant York (1941), The White Cliffs of Dover (1942) and Meet Me in St Louis (1944). In the latter, she is charming as a New Yorker at a family party, whose schedule is filled maliciously to stop 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 sequels to the hugely successful Lassie Come Home (1943), in which a young star had played the female character who assists the canine to escape to the family. In the subsequent film, Lockhart played the now grown-up character.
The affectionate way in which she interacted with both Lassie and her son, Laddie, protagonist of a wartime story in enemy-held Norway, was in the consideration of the creators when it came to casting the Lassie TV series 13 years later.
Transition to Television and Broadway Achievement
Although she was given major roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her movie career was getting her nowhere 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 best newcomer.
A further significant run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a doctor and mother figure. She also appeared frequently in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy workload persisted for the following five decades, with a recurring role in General Hospital between 1984 and 1998. Among her many guest appearances were as herself in a 1988 episode of a talkshow, where the presenter finds a lost collie, and in another sitcom in 1995 as the parent of a restaurant manager.
Final Roles and Achievements
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 digital cameo as a school principal. She took joy in learning how much of an inspiration the first series had been to future astronauts, and often attended the organization’s launches and other events. In 2013 her work as a unpaid representative brought her its Exceptional Public Achievement Medal.
Among her few later feature films was the fantasy, Troll (1986) in which she portrayed a witch, with her own daughter, Anne Lockhart, playing her earlier self.
Personal Life and Family
In 1951 she wed 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 remembered by her daughters and four grandkids.
