June Lockhart, who died at the age of 100, began her professional journey in films, but achieved recognition after moving almost entirely to television. Having been offered few opportunities to shine in films from her first appearance as a youngster in 1938 until 1947, she excelled on TV in many beloved series, especially in Lassie.
Her Memorable Role in Lassie
Taking over 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 young Timmy Martin, whose collie was the titular hero of the series.
Even with playing a mother figure, Lockhart adeptly avoided being outshone by the smart 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 commercial”. After she left the series, Lockhart commented: “In six chaste years of playing a country spouse and mother, I was rarely permitted to kiss my co-star on the face.”
Journey into Lost in Space
Lockhart went straight into another hit, Lost in Space (1965-68), a partly comedic sci-fi series aimed mostly at children 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 survive visual effects. As the show continued, the narrative became less and less about this space clan and increasingly about the boy and his bond with a robot, and the timid villain Dr Zachary Smith.
Beginnings in Entertainment
Lockhart’s movie first role, 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 Canada-native 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 performance, at the tender age of six, came in a non-singing role in an opera at the Metropolitan Opera in New York (1931).
Cinema Career
When her parent was given a deal by a motion picture studio, after his success on Broadway, she relocated with her parents to Hollywood, where Gene made approximately 300 films. After going to 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 arranged maliciously to prevent Lockhart dancing with her brother.
More significantly, although she did not realize it at the time, was Son of Lassie (1945). It was one of several follow-ups to the extremely successful Lassie Come Home (1943), in which another actress had played the female character who helps the canine to return to the owners. In the subsequent film, Lockhart played the now grown-up character.
The loving way in which she handled both Lassie and her son, Laddie, hero of a World War II adventure in enemy-held Norway, was in the minds of the producers when it came to casting the Lassie TV series 13 years later.
Television and Theater Career
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 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 most promising newcomer.
A further significant run came with Petticoat Junction (1968-70), set in a country 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 hectic workload continued for the next five decades, with a recurring role in General Hospital between 1984 and 1998. Among her many one-off appearances were as herself in a 1988 episode of a comedy series, where the host finds a lost collie, and in another sitcom in 1995 as the parent 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 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 influence the original series had been to later 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 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 married John Maloney, a doctor and former Navy doctor. 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 daughters and four grandkids.
