Launching her career in films, June Lockhart, who died aged 100, found her biggest success after switching predominantly to television. Having been offered limited chances to shine in movies from her first appearance as a youngster in 1938 until 1947, she thrived on television in numerous popular series, especially in Lassie.
Her Iconic Role in Lassie
Taking over from another actress in 1958, Lockhart remained in the show until 1964. She played Ruth Martin, wed to agriculturalist Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose collie was the titular hero of the series.
Despite playing a housewife, Lockhart adeptly avoided being outshone by the brilliant animal star. She characterized the program as “a fairy tale about people on a farm in which the canine solves all the problems in 22 minutes, in time for the last commercial”. After she left the series, Lockhart remarked: “In six sexless years of playing a rural spouse and parent, I was hardly ever allowed to kiss my co-star on the face.”
Starring in Lost in Space
Lockhart went directly into a second successful series, Lost in Space (1965-68), a semi-spoof sci-fi series aimed primarily at children and based by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two scientists investigating distant planets. Lockhart had to spend the majority of her time deftly trying to navigate special effects. As the show progressed, the storyline became increasingly less about this interstellar clan and more about the boy and his friendship with a robot, and the timid villain Dr Zachary Smith.
Beginnings in Show Business
Lockhart’s feature film 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 actual parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canada-native Gene were both actors in many of films, as well as on theater, it was almost 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 opera at the Metropolitan Opera in New York (1931).
Cinema Career
When her father was offered a deal by a motion picture studio, after his acclaim on Broadway, she relocated with her parents to Hollywood, where Gene made approximately 300 films. After attending school in Beverly Hills, June started her professional life in movies, 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 latter, she is delightful as a New Yorker at a family party, whose dance card is arranged maliciously to prevent Lockhart interacting with her sibling.
More significantly, although she did not realize it at the time, was Son of Lassie (1945). It was one of multiple follow-ups to the extremely successful Lassie Come Home (1943), in which a young star had played the female character who assists the dog to return to the owners. In the later film, Lockhart played the now grown-up character.
The loving way in which she interacted with both Lassie and her son, Laddie, protagonist of a World War II adventure in Nazi-occupied Norway, was in the consideration of the creators when it came to selecting the Lassie TV series 13 years later.
TV and Stage Career
Although she was given major roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her movie career was getting her nowhere and that TV would be the solution. 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 additional significant run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a physician and maternal character. She also featured frequently in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic schedule 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 herself in a 1988 episode of a talkshow, where the host finds a lost collie, and in another sitcom in 1995 as the mother of a restaurant manager.
Later Roles and Achievements
Her last TV appearance came in 2021 as the voice of Alpha Control in an episode of a streaming service’s remake of Lost in Space. In the big screen version featuring famous actors (1998), she had a digital cameo as a school principal. She took joy in learning how much of an influence 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 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 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 marriage ended in separation, as did her second marriage, to John Lindsay, an designer.
She is survived by her daughters and four grandchildren.
