June Lockhart: A Lifetime of TV Stardom from Lassie to Lost in Space

Launching her career in films, June Lockhart, who died aged 100, achieved her biggest success after switching largely to television. Having been offered few opportunities to shine in movies from her debut as a youngster in 1938 until 1947, she thrived on television in many popular series, especially in Lassie.

Portraying Ruth Martin on Lassie

Taking over 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 seven-year-old Timmy Martin, whose dog was the eponymous hero of the series.

In her part as a homemaker, Lockhart somehow managed to avoid being totally overshadowed by the intelligent canine. She characterized the show as “a fantasy about people on a farm in which the canine resolves all the problems in 22 minutes, in time for the last commercial”. After she left the show, Lockhart commented: “In six chaste years of playing a rural wife and mother, I was rarely permitted to kiss my co-star on the cheek.”

Starring in Lost in Space

Lockhart went straight into another hit, Lost in Space (1965-68), a partly comedic science fiction series targeted primarily at children and inspired by The Swiss Family Robinson. Lockhart and another actor portrayed Maureen and John Robinson, two scientists exploring alien planets. Lockhart had to spend the majority of her time skillfully trying to survive visual effects. As the series progressed, the narrative became increasingly less about this space clan and increasingly about the boy and his friendship with a robot, and the timid villain Dr Zachary Smith.

Initial Career and Family Background

Lockhart’s movie first role, 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 Canada-native Gene were both performers in dozens of films, as well as on stage, it was nearly certain that June, who was born in New York, would join the entertainment industry.

Her first theatrical performance, 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 moved with her parents to Hollywood, where Gene made approximately 300 films. After attending school in Beverly Hills, June started her professional life in movies, mainly 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 charming as a New Yorker at a household party, whose schedule is arranged spitefully to prevent Lockhart interacting with her brother.

More significantly, although she did not know it at the time, was Son of Lassie (1945). It was one of several follow-ups to the extremely successful Lassie Come Home (1943), in which a young star had played the female character who assists the canine to return to the owners. In the subsequent film, Lockhart played the now adult version.

The loving way in which she handled both Lassie and her offspring, Laddie, hero of a World War II story in Nazi-occupied Norway, was in the consideration of the producers when it came to casting the Lassie TV series 13 years later.

Television 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 television would be the answer. Before going 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 best newcomer.

A further substantial run came with Petticoat Junction (1968-70), set in a country 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 regular 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 Roles and Achievements

Her final TV appearance came in 2021 as the voice of Alpha Control in an episode of a streaming service’s remake of Lost in Space. In the big screen version featuring well-known actors (1998), she had a holographic cameo as a school principal. She took joy in learning how much of an inspiration 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 volunteer spokesperson brought her its Exceptional Public Achievement Medal.

Among her few subsequent feature films was the fantasy, Troll (1986) in which she played a witch, with her own daughter, Anne Lockhart, playing her earlier self.

Personal Information

In 1951 she married John Maloney, a physician and former Navy doctor. In addition to Anne, they had a second daughter, June. That union ended in divorce, as did her subsequent marriage, to John Lindsay, an designer.

She is survived by her daughters and four grandkids.
