Starting her career in cinema, June Lockhart, who passed on aged 100, found her greatest success after shifting largely to television. Having been offered few chances to shine in films from her debut as a child in 1938 until 1947, she thrived on television in numerous popular series, especially in Lassie.
Her Iconic Role in Lassie
Stepping in from another actress in 1958, Lockhart continued in the show until 1964. She played Ruth Martin, wed to agriculturalist Paul Martin and the foster mother of young Timmy Martin, whose collie was the titular star of the series.
In her part as a homemaker, Lockhart somehow managed to avoid being completely upstaged by the intelligent canine. She described the program as “a fairy tale about families on a farm in which the canine solves all the problems in 22 minutes, in time for the last commercial”. After she departed the series, Lockhart commented: “In six chaste years of playing a country spouse and parent, I was hardly ever allowed to kiss my co-star on the face.”
Journey into Lost in Space
Lockhart went directly into a second successful series, Lost in Space (1965-68), a partly comedic science fiction 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 most of her time deftly trying to navigate visual effects. As the show continued, the narrative became less and less about this interstellar family and more about the young son and his friendship with a robot, and the timid antagonist Dr Zachary Smith.
Beginnings in Show Business
Lockhart’s feature film debut, at the 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 UK-native Kathleen and Canadian-born Gene were both actors in dozens of films, as well as on theater, it was nearly certain 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).
Hollywood Career
When her father was offered a contract by a film studio, after his success on Broadway, she relocated with her parents to Hollywood, where Gene made around 300 films. After going to school in Beverly Hills, June began her professional life in movies, 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 delightful as a New Yorker at a family party, whose schedule is filled spitefully to prevent Lockhart dancing with her brother.
More significantly, although she did not know 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 female character who helps the canine to return to the family. In the subsequent film, Lockhart played the now grown-up character.
The affectionate 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 consideration of the creators when it came to casting the Lassie TV series 13 years later.
Television and Theater Work
Although she was offered major roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her movie career was getting her nowhere and that TV would be the solution. Before embarking in a different direction, she won praise on Broadway in For Love or Money (1947), a comedy for which she won a Tony award as best newcomer.
A additional significant run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a physician 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 busy schedule persisted for the following five decades, with a regular 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 stray collie, and in another sitcom in 1995 as the mother of a dining manager.
Final Roles and Achievements
Her last 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 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 inspiration the first series had been to later astronauts, and often participated in the organization’s launches and other events. In 2013 her work as a volunteer spokesperson brought her its prestigious award.
Among her limited subsequent feature films was the fantasy, Troll (1986) in which she portrayed a sorceress, with her own daughter, Anne Lockhart, playing her earlier self.
Personal Details
In 1951 she wed 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 second marriage, to John Lindsay, an designer.
She is remembered by her daughters and four grandchildren.
