June Lockhart, who died at the remarkable age of 100, started her professional journey in movies, but gained fame after moving almost exclusively to TV. Having been given limited chances to shine in movies from her debut as a child in 1938 until 1947, she excelled on TV in many popular series, most notably in Lassie.
Portraying Ruth Martin on Lassie
Stepping in from another actress in 1958, Lockhart remained in the show until 1964. She played Ruth Martin, married to agriculturalist Paul Martin and the adoptive mother of young Timmy Martin, whose collie was the eponymous star of the series.
In her role as a homemaker, Lockhart somehow managed to avoid being completely upstaged by the intelligent canine. She characterized the program as “a fairy tale about families on a farm in which the dog resolves all the problems in 22 minutes, in time for the last commercial”. After she left the show, Lockhart commented: “In six sexless years of playing a rural wife and parent, I was rarely permitted to kiss my on-screen husband on the face.”
Featuring in Lost in Space
Lockhart went straight into another successful series, Lost in Space (1965-68), a partly comedic sci-fi series aimed primarily at young audiences and based by The Swiss Family Robinson. Lockhart and another actor portrayed Maureen and John Robinson, two scientists exploring alien planets. Lockhart had to spend the majority of her time skillfully trying to survive special effects. As the series continued, the narrative became less and less about this space 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 actual parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canadian-born Gene were both actors in many of films, as well as on stage, it was almost inevitable that June, who was born in New York, would join show business.
Her first stage appearance, at the age of six, came in a non-musical role in an musical production at the Metropolitan Opera in New York (1931).
Move to Hollywood and Film Roles
When her parent was offered a deal by a motion picture studio, after his success on Broadway, she moved with her parents to Hollywood, where Gene made around 300 films. After going to school in Beverly Hills, June started her career in films, mainly 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 charming as a New Yorker at a household party, whose schedule is filled spitefully to prevent Lockhart dancing with her brother.
More importantly, although she did not know it at the time, was Son of Lassie (1945). It was one of several sequels to the hugely successful Lassie Come Home (1943), in which a young star 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, protagonist of a wartime adventure in enemy-held Norway, was in the consideration of the creators when it came to casting the Lassie TV series 13 years later.
TV and Stage Career
Although she was given major roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded 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 additional substantial run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a doctor and mother figure. She also appeared 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 regular 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 host finds a stray collie, and in another sitcom in 1995 as the parent of a restaurant manager.
Final Roles and Contributions
Her last TV credit came in 2021 as the voice of Alpha Control in an episode of a digital platform’s remake of Lost in Space. In the big screen version featuring famous actors (1998), she had a holographic cameo as a school principal. She took joy in learning how much of an influence the original series had been to future astronauts, and often attended the agency’s launches and other events. In 2013 her work as a unpaid spokesperson brought her its Exceptional Public Achievement Medal.
Among her limited 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 Information
In 1951 she wed John Maloney, a doctor and former Navy doctor. In addition to Anne, they had a second daughter, June. That marriage ended in divorce, as did her subsequent marriage, to John Lindsay, an architect.
She is survived by her children and four grandchildren.
