Launching her career in cinema, June Lockhart, who passed on aged 100, found her biggest success after switching largely to television. Having been given few chances to shine in movies from her first appearance as a child in 1938 until 1947, she thrived on TV in numerous popular series, especially 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 farmer Paul Martin and the adoptive mother of young Timmy Martin, whose collie was the eponymous hero of the series.
Even with playing a mother figure, Lockhart adeptly avoided being outshone by the smart animal star. She described the show as “a fairy tale about families on a farm in which the dog resolves all the issues in 22 minutes, in time for the last advertisement”. After she departed the show, Lockhart commented: “In six sexless years of playing a rural wife and mother, I was hardly ever permitted to kiss my on-screen husband on the face.”
Featuring in Lost in Space
Lockhart went straight into another hit, Lost in Space (1965-68), a partly comedic sci-fi series targeted primarily at children and inspired by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two researchers investigating distant planets. Lockhart had to spend the majority of her time deftly trying to survive visual effects. As the show continued, the storyline became increasingly less about this interstellar clan and increasingly about the young son and his friendship with a mechanical being, and the timid villain Dr Zachary Smith.
Initial Career and Family Influence
Lockhart’s feature film debut, at the young age of 13, had come as Belinda Cratchit in A Christmas Carol (1938). In the roles of her parents, Bob and Mrs Cratchit, were her real-life parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canadian-born Gene were both performers in many of films, as well as on stage, it was almost inevitable that June, who was born in New York, would enter show business.
Her first stage appearance, at the age of six, came in a non-musical role in an opera at the Metropolitan Opera in New York (1931).
Hollywood Work
When her father was given a deal by a film studio, after his acclaim on Broadway, she moved with her family to Hollywood, where Gene made around 300 films. After attending school in Beverly Hills, June started her professional life in films, mostly in small 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 household party, whose schedule is arranged spitefully to prevent Lockhart dancing with her brother.
More importantly, although she did not realize 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 another actress had played the female character who helps the canine to escape to the owners. In the later film, Lockhart played the now adult character.
The affectionate way in which she handled both Lassie and her son, Laddie, protagonist of a World War II story in enemy-held Norway, was in the minds of the creators when it came to casting the Lassie TV series 13 years later.
Television and Stage Work
Although she was given leading roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her film career was getting her nowhere and that television would be the answer. Before embarking in a new direction, she received praise on Broadway in For Love or Money (1947), a comedy for which she won a Tony award as most promising newcomer.
A further substantial run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a doctor and maternal character. She also appeared frequently in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic schedule continued for the next 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 comedy series, where the host finds a stray collie, and in another sitcom in 1995 as the parent of a dining manager.
Final Career and Impact
Her last TV credit came in 2021 as the voice of Alpha Control in an episode of a digital platform’s new version of Lost in Space. In the big screen version featuring well-known 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 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 few later feature films was the fantasy, Troll (1986) in which she portrayed 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 a second daughter, June. That union ended in separation, as did her subsequent marriage, to John Lindsay, an designer.
She is survived by her children and four grandchildren.
