June Lockhart, who died at the age of 100, started her professional journey in films, but achieved recognition after moving almost entirely to television. Having been given few opportunities to shine in films from her debut as a youngster in 1938 until 1947, she excelled on TV in many popular series, most notably in Lassie.
Her Iconic Role in Lassie
Stepping in from another actress in 1958, Lockhart continued in the series until 1964. Her role was Ruth Martin, married to agriculturalist Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose collie was the eponymous star of the series.
Even with playing a mother figure, Lockhart adeptly avoided being outshone by the smart dog. She characterized the show as “a fantasy about families on a rural property in which the canine resolves all the problems 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 mother, I was rarely permitted to peck my on-screen husband on the cheek.”
Journey into Lost in Space
Lockhart went straight into another hit, Lost in Space (1965-68), a semi-spoof sci-fi series aimed mostly at children and based by The Swiss Family Robinson. Lockhart and another actor portrayed Maureen and John Robinson, two scientists investigating alien planets. Lockhart had to spend most of her time skillfully trying to navigate special effects. As the show continued, the narrative became increasingly less about this interstellar clan and increasingly about the young son and his bond with a robot, and the timid villain Dr Zachary Smith.
Start in Show Business
Lockhart’s movie debut, at the young 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 real-life parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canadian-born Gene were both performers in many of movies, as well as on stage, it was nearly inevitable that June, who was born in New York, would join show business.
Her first stage appearance, at the tender 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 parent was offered a deal by a motion picture studio, after his acclaim on Broadway, she moved with her family to Hollywood, where Gene made approximately 300 films. After going to school in Beverly Hills, June started her professional life in movies, mainly 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 latter, she is delightful as a New Yorker at a household party, whose schedule is filled maliciously to stop Lockhart interacting 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 extremely successful Lassie Come Home (1943), in which another actress had played the female character who assists the dog to escape to the owners. In the subsequent film, Lockhart played the now grown-up version.
The affectionate way in which she interacted with both Lassie and her son, Laddie, hero of a wartime adventure in enemy-held Norway, was in the consideration of the creators when it came to selecting the Lassie TV series 13 years later.
Transition to Television and Stage Achievement
Although she was offered leading roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her movie career was stagnating and that television would be the solution. Before embarking in a new direction, she received acclaim on Broadway in For Love or Money (1947), a humorous play for which she won a Tony award as best newcomer.
A additional substantial run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a physician and mother figure. She also appeared regularly in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic 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 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 narration of Alpha Control in an episode of a streaming service’s new version of Lost in Space. In the movie version featuring well-known actors (1998), she had a digital cameo as a school principal. She took pleasure in learning how much of an influence 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 witch, with her own daughter, Anne Lockhart, playing her earlier self.
Private Details
In 1951 she wed John Maloney, a doctor and former Navy medical officer. In addition to Anne, they had another daughter, June. That marriage ended in separation, as did her subsequent marriage, to John Lindsay, an architect.
She is remembered by her children and four grandchildren.
