June Lockhart, who passed away at the remarkable age of 100, started her professional journey in films, but gained recognition after moving almost entirely to TV. Having been offered limited opportunities to shine in films from her first appearance as a youngster in 1938 until 1947, she excelled on television in numerous popular series, especially in Lassie.
Portraying Ruth Martin on Lassie
Taking over from a previous star in 1958, Lockhart remained in the series until 1964. Her role was Ruth Martin, married to farmer Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose dog was the titular hero of the series.
Despite playing a housewife, Lockhart adeptly avoided being outshone by the brilliant dog. She characterized the program as “a fantasy about people on a farm in which the canine solves all the problems in 22 minutes, in time for the last advertisement”. After she left the show, Lockhart commented: “In six sexless years of playing a country spouse and parent, I was hardly ever allowed to peck my co-star on the cheek.”
Starring in Lost in Space
Lockhart went straight into a second hit, Lost in Space (1965-68), a semi-spoof sci-fi series aimed primarily at children and based by The Swiss Family Robinson. Lockhart and her co-star played Maureen and John Robinson, two scientists exploring alien planets. Lockhart had to spend the majority of her time deftly trying to survive special effects. As the series continued, the narrative became increasingly less about this space family and increasingly about the young son and his friendship with a robot, and the timid antagonist Dr Zachary Smith.
Early Career and Family Background
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 actual 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 almost certain that June, who was born in New York, would join show business.
Her first theatrical appearance, at the age of six, came in a non-singing role in an musical production at the Metropolitan Opera in New York (1931).
Move to Hollywood and Film Roles
When her father was given a deal by a film 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 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 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 girl who assists the dog to escape to the family. In the later film, Lockhart played the now grown-up character.
The loving way in which she handled both Lassie and her offspring, Laddie, hero 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.
Shift to Television and Stage Success
Although she was offered major 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 TV would be the solution. Before embarking in a new 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 rural hotel, where Lockhart is a physician and maternal character. She also featured regularly in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy schedule continued for the next five decades, with a recurring 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 mother of a dining manager.
Final Roles and Contributions
Her final 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 movie version featuring famous actors (1998), she had a digital 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 unpaid 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 earlier self.
Personal Information
In 1951 she wed John Maloney, a physician and former Navy medical officer. In addition to Anne, they had a second daughter, June. That marriage ended in separation, as did her subsequent marriage, to John Lindsay, an architect.
She is remembered by her children and four grandchildren.
