Starting her career in films, June Lockhart, who died aged 100, achieved her biggest success after switching largely to television. Having been given limited opportunities to shine in films from her first appearance as a child in 1938 until 1947, she thrived on television in numerous beloved series, most notably in Lassie.

Portraying Ruth Martin on Lassie

Stepping in from a previous star 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 dog was the eponymous star of the series.

Even with playing a housewife, Lockhart skillfully avoided being outshone by the smart animal star. 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 left the show, Lockhart commented: “In six chaste years of playing a rural wife and mother, I was rarely allowed to kiss my on-screen husband on the face.”

Starring in Lost in Space

Lockhart went directly into a second successful series, Lost in Space (1965-68), a partly comedic sci-fi series targeted mostly at children and inspired by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two researchers investigating alien planets. Lockhart had to spend the majority of her time deftly trying to navigate special effects. As the series progressed, the storyline became increasingly less about this space clan and increasingly about the boy and his friendship with a mechanical being, 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 mother and father, Bob and Mrs Cratchit, were her real-life parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canadian-born Gene were both performers in dozens of films, as well as on stage, it was nearly inevitable that June, who was born in New York, would enter the entertainment industry.

Her first stage appearance, at the age of six, came in a non-singing role in an opera at the Metropolitan Opera in New York (1931).

Cinema Work

When her father was given a deal by a film 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 began her career in films, mostly 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 latter, she is delightful as a New Yorker at a family party, whose dance card is arranged spitefully to prevent Lockhart dancing with her sibling.

More significantly, although she did not realize it at the time, was Son of Lassie (1945). It was one of multiple 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 owners. In the subsequent film, Lockhart played the now adult version.

The loving way in which she interacted with both Lassie and her offspring, Laddie, hero of a wartime story in Nazi-occupied Norway, was in the minds of the producers when it came to casting the Lassie TV series 13 years later.

Transition to Television and Stage Achievement

Although she was given major roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her movie career was stagnating and that television would be the answer. Before going in a new direction, she received acclaim 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 rural hotel, where Lockhart is a doctor and mother figure. She also featured frequently in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic workload continued for the following 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 talkshow, where the host finds a lost collie, and in another sitcom in 1995 as the mother of a dining manager.

Later Career and Legacy

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 starring famous actors (1998), she had a digital cameo as a school principal. She took joy in learning how much of an influence 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 representative brought her its prestigious award.

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

Private Details

In 1951 she wed John Maloney, a doctor and former Navy medical officer. In addition to Anne, they had another daughter, June. That union ended in separation, as did her subsequent marriage, to John Lindsay, an architect.

She is survived by her daughters and four grandkids.
