Launching her career in cinema, June Lockhart, who passed on aged 100, achieved her biggest success after shifting predominantly to television. Having been offered few chances to shine in movies from her debut as a child in 1938 until 1947, she thrived on TV in numerous beloved series, especially in Lassie.
Becoming Ruth Martin on Lassie
Stepping in from another actress in 1958, Lockhart continued 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 collie was the titular star of the series.
In her part as a homemaker, Lockhart somehow managed to avoid being completely overshadowed by the clever dog. She described the show as “a fantasy about people on a farm in which the canine resolves all the problems in 22 minutes, in time for the last advertisement”. After she departed the series, Lockhart remarked: “In six sexless years of playing a country spouse and mother, I was hardly ever allowed to peck my on-screen husband on the face.”
Journey into Lost in Space
Lockhart went directly into a second hit, Lost in Space (1965-68), a partly comedic science fiction series targeted mostly at children and inspired by The Swiss Family Robinson. Lockhart and her co-star played Maureen and John Robinson, two researchers investigating distant planets. Lockhart had to spend the majority of her time skillfully trying to survive visual effects. As the series progressed, the narrative became increasingly less about this interstellar clan and increasingly about the boy and his bond with a mechanical being, and the cowardly villain Dr Zachary Smith.
Initial Career and Family Influence
Lockhart’s feature film debut, at the young 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 actual parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canada-native Gene were both performers in dozens 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 performance, at the age of six, came in a non-musical role in an musical production at the Metropolitan Opera in New York (1931).
Cinema Career
When her father was offered a deal by a motion picture studio, after his success on Broadway, she moved with her parents to Hollywood, where Gene made approximately 300 films. After attending school in Beverly Hills, June began her professional life in films, mostly 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 last one, she is delightful as a New Yorker at a household party, whose schedule is filled maliciously 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 another actress had played the girl who assists the dog to escape to the owners. In the subsequent film, Lockhart played the now adult version.
The loving way in which she interacted with both Lassie and her son, Laddie, protagonist of a wartime adventure in enemy-held Norway, was in the minds of the creators when it came to casting the Lassie TV series 13 years later.
Shift to Television and Stage Achievement
Although she was offered leading roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her film career was stagnating and that television would be the solution. Before embarking in a different 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 country hotel, where Lockhart is a physician and maternal character. She also appeared 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 following 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.
Final Roles and Contributions
Her last TV appearance came in 2021 as the narration of Alpha Control in an episode of a digital platform’s remake of Lost in Space. In the big screen version starring famous actors (1998), she had a holographic 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 participated in the agency’s launches and other events. In 2013 her work as a unpaid representative brought her its prestigious award.
Among her limited later feature films was the fantasy, Troll (1986) in which she played a sorceress, with her own daughter, Anne Lockhart, playing her younger self.
Personal Life and Family
In 1951 she wed John Maloney, a physician and former Navy medical officer. In addition to Anne, they had another daughter, June. That marriage ended in divorce, as did her subsequent marriage, to John Lindsay, an architect.
She is remembered by her children and four grandchildren.
