Starting her career in cinema, June Lockhart, who died aged 100, found her greatest success after shifting predominantly to the small screen. Having been given limited chances to excel in films from her debut as a youngster in 1938 until 1947, she excelled on TV in numerous popular series, especially in Lassie.
Her Memorable Role in Lassie
Stepping in from a previous star in 1958, Lockhart remained in the series until 1964. She played Ruth Martin, wed to farmer Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose dog was the titular hero of the series.
In her part as a housewife, Lockhart somehow managed to avoid being totally overshadowed by the intelligent canine. She characterized the show as “a fantasy about families on a rural property in which the dog solves 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 country wife and mother, I was hardly ever allowed to kiss my co-star on the face.”
Featuring in Lost in Space
Lockhart went straight into a second successful series, Lost in Space (1965-68), a partly comedic sci-fi series targeted primarily at young audiences and inspired by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two scientists exploring alien planets. Lockhart had to spend the majority of her time deftly trying to navigate visual effects. As the series continued, the storyline became increasingly less about this interstellar family and increasingly about the young son and his bond with a robot, and the cowardly villain Dr Zachary Smith.
Beginnings in Entertainment
Lockhart’s movie first role, at the 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 real-life parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canada-native Gene were both performers in many of movies, as well as on stage, it was nearly inevitable that June, who was born in New York, would enter show business.
Her first theatrical performance, 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 parent was offered a contract by a motion picture studio, after his success on Broadway, she relocated with her parents to Hollywood, where Gene made around 300 films. After attending school in Beverly Hills, June started her career 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 last one, she is delightful as a New Yorker at a household party, whose dance card is arranged maliciously to prevent Lockhart interacting with her sibling.
More significantly, although she did not know it at the time, was Son of Lassie (1945). It was one of multiple follow-ups to the hugely successful Lassie Come Home (1943), in which a young star had played the female character who assists the canine to return to the family. In the later film, Lockhart played the now grown-up version.
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 minds of the producers when it came to selecting the Lassie TV series 13 years later.
TV and Theater Work
Although she was offered leading 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 answer. Before going in a new 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 further substantial run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a physician and mother figure. She also appeared regularly in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic schedule persisted for the following 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 presenter finds a stray collie, and in another sitcom in 1995 as the parent of a restaurant manager.
Final Roles and Achievements
Her final 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 digital cameo as a school principal. She took pleasure 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 volunteer representative brought her its prestigious award.
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 younger self.
Personal Life and Family
In 1951 she wed John Maloney, a physician and former Navy doctor. In addition to Anne, they had a second daughter, June. That marriage ended in divorce, as did her second marriage, to John Lindsay, an designer.
She is survived by her children and four grandchildren.
