Starting her career in films, June Lockhart, who passed on aged 100, achieved her biggest success after switching largely to television. Having been offered limited chances to excel in movies from her first appearance as a youngster in 1938 until 1947, she thrived on television in many popular series, most notably in Lassie.
Becoming Ruth Martin on Lassie
Stepping in from another actress in 1958, Lockhart continued in the series until 1964. Her role was Ruth Martin, wed to agriculturalist Paul Martin and the foster mother of seven-year-old Timmy Martin, whose collie was the titular star of the series.
Even with playing a housewife, Lockhart skillfully avoided being overshadowed by the smart dog. She characterized the show as “a fantasy about families on a rural property in which the dog resolves all the problems in 22 minutes, in time for the last advertisement”. After she left the series, Lockhart remarked: “In six chaste years of playing a country spouse and mother, I was rarely permitted to kiss my co-star on the cheek.”
Starring in Lost in Space
Lockhart went directly into another successful series, Lost in Space (1965-68), a semi-spoof science fiction series targeted primarily at young audiences 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 the majority of her time skillfully trying to navigate special effects. As the show continued, the narrative became increasingly less about this space clan and more about the boy and his bond with a mechanical being, and the timid antagonist Dr Zachary Smith.
Beginnings in Show Business
Lockhart’s feature film first role, at the 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 real-life parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canadian-born Gene were both performers in dozens of films, as well as on stage, it was nearly inevitable that June, who was born in New York, would enter show business.
Her first stage performance, at the tender age of six, came in a non-singing role in an opera at the Metropolitan Opera in New York (1931).
Hollywood Work
When her father was offered a contract by a motion picture studio, after his success on Broadway, she relocated with her parents to Hollywood, where Gene made around 300 films. After going to school in Beverly Hills, June started her professional life in films, mostly in small 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 delightful as a New Yorker at a household party, whose dance card is arranged 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 helps the canine to return 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 offspring, Laddie, protagonist of a World War II story in enemy-held Norway, was in the minds of the producers when it came to casting the Lassie TV series 13 years later.
Shift to Television and Stage Achievement
Although she was offered major roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her movie career was getting her nowhere and that TV would be the answer. Before going in a different direction, she received praise 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 featured 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 following five decades, with a regular role in General Hospital between 1984 and 1998. Among her many one-off 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.
Later Roles and Contributions
Her final TV credit 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 featuring well-known actors (1998), she had a holographic cameo as a school principal. She took pleasure in learning how much of an inspiration the first series had been to future astronauts, and often participated in the organization’s launches and other events. In 2013 her work as a unpaid spokesperson brought her its prestigious award.
Among her few subsequent feature films was the fantasy, Troll (1986) in which she played a sorceress, with her own daughter, Anne Lockhart, playing her younger self.
Personal Details
In 1951 she wed John Maloney, a physician and former Navy doctor. In addition to Anne, they had another daughter, June. That marriage ended in divorce, as did her second marriage, to John Lindsay, an designer.
She is survived by her children and four grandkids.
