June Lockhart, who passed away at the age of 100, began her professional journey in movies, but gained recognition after moving almost exclusively to television. Having been given limited opportunities to excel in films from her debut as a youngster in 1938 until 1947, she thrived on TV in many popular series, especially in Lassie.
Her Memorable Role in Lassie
Taking over from another actress in 1958, Lockhart remained in the show until 1964. She played Ruth Martin, married to farmer Paul Martin and the foster mother of seven-year-old Timmy Martin, whose dog was the titular hero of the series.
In her role as a housewife, Lockhart somehow managed to avoid being totally upstaged by the intelligent dog. She characterized the show as “a fairy tale about families on a rural property in which the dog resolves all the problems in 22 minutes, in time for the last commercial”. After she departed the series, Lockhart commented: “In six sexless years of playing a rural spouse and parent, I was rarely allowed to peck my co-star on the cheek.”
Starring in Lost in Space
Lockhart went directly into another hit, Lost in Space (1965-68), a partly comedic science fiction series aimed mostly at children and based by The Swiss Family Robinson. Lockhart and her co-star portrayed Maureen and John Robinson, two researchers investigating distant planets. Lockhart had to spend most of her time deftly trying to navigate visual effects. As the series progressed, the narrative became less and less about this interstellar family and increasingly about the young son and his bond with a robot, and the timid villain Dr Zachary Smith.
Start in Entertainment
Lockhart’s movie debut, at the age of 13, had come as Belinda Cratchit in A Christmas Carol (1938). In the parts of her mother and father, Bob and Mrs Cratchit, were her actual parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canadian-born Gene were both performers in dozens of movies, as well as on stage, it was almost inevitable that June, who was born in New York, would enter show business.
Her first theatrical appearance, at the tender age of six, came in a non-singing role in an musical production at the Metropolitan Opera in New York (1931).
Transition to Hollywood and Film Roles
When her father was given a deal by a motion picture studio, after his success on Broadway, she moved with her parents to Hollywood, where Gene made approximately 300 films. After attending school in Beverly Hills, June started her career in movies, mainly in minor roles in acclaimed 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 family party, whose schedule is filled spitefully to stop Lockhart dancing 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 girl who assists the canine 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 offspring, Laddie, protagonist of a wartime story 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 Broadway Achievement
Although she was given leading roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her movie career was getting her nowhere and that television would be the answer. Before embarking in a different direction, she won 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 doctor and mother figure. She also featured regularly in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic workload persisted 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 talkshow, where the host finds a lost collie, and in another sitcom in 1995 as the mother of a restaurant manager.
Later Career and Impact
Her last TV appearance 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 featuring famous actors (1998), she had a digital cameo as a school principal. She took pleasure in learning how much of an influence the original series had been to later astronauts, and often participated in the agency’s launches and other events. In 2013 her work as a volunteer spokesperson brought her its Exceptional Public Achievement Medal.
Among her few later feature films was the fantasy, Troll (1986) in which she played a witch, 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 medical officer. In addition to Anne, they had a second daughter, June. That union ended in divorce, as did her second marriage, to John Lindsay, an architect.
She is remembered by her children and four grandkids.
