June Lockhart: A Lifetime of Television Success from Lassie to Lost in Space

Launching her career in cinema, June Lockhart, who passed on aged 100, achieved her biggest success after switching largely to television. Having been offered few chances to shine in films from her debut as a youngster in 1938 until 1947, she excelled on television in many beloved series, most notably in Lassie.

Her Memorable Role in Lassie

Stepping in from a previous star in 1958, Lockhart remained in the series until 1964. Her role was Ruth Martin, wed to agriculturalist Paul Martin and the adoptive mother of young Timmy Martin, whose dog was the titular hero of the series.

Despite playing a housewife, Lockhart adeptly avoided being outshone by the smart dog. She described the show as “a fairy tale about families on a farm in which the dog solves all the issues in 22 minutes, in time for the last advertisement”. After she departed the show, Lockhart remarked: “In six chaste years of playing a rural wife and mother, I was hardly ever permitted to peck my co-star on the cheek.”

Adventure into Lost in Space

Lockhart went straight into another successful series, Lost in Space (1965-68), a semi-spoof sci-fi series aimed primarily at children and inspired by The Swiss Family Robinson. Lockhart and her co-star played Maureen and John Robinson, two scientists exploring distant planets. Lockhart had to spend most of her time skillfully trying to navigate special effects. As the series progressed, the narrative became less and less about this space clan and increasingly about the young son and his friendship with a robot, and the timid villain Dr Zachary Smith.

Initial Career and Family Background

Lockhart’s feature film debut, at the young age of 13, had come as Belinda Cratchit in A Christmas Carol (1938). In the parts of her mother and father, Bob and Mrs Cratchit, were her actual parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canada-native Gene were both actors in many of films, as well as on stage, it was almost inevitable that June, who was born in New York, would enter show business.

Her first stage performance, at the tender age of six, came in a non-musical role in an musical production at the Metropolitan Opera in New York (1931).

Transition to Hollywood and Film Roles

When her parent was offered a deal by a film studio, after his acclaim on Broadway, she relocated with her family to Hollywood, where Gene made around 300 films. After going to school in Beverly Hills, June began her professional life in movies, mainly in small 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 maliciously 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 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 escape to the owners. In the later film, Lockhart played the now adult version.

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 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 offered major roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her film career was getting her nowhere and that TV would be the answer. Before going in a new direction, she received 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 doctor and maternal character. She also appeared frequently in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic workload continued for the next five decades, with a recurring role in General Hospital between 1984 and 1998. Among her many guest appearances were as the actress in a 1988 episode of a talkshow, where the host finds a stray collie, and in another sitcom in 1995 as the parent of a restaurant manager.

Later Career and Impact

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 starring famous actors (1998), she had a digital cameo as a school principal. She took joy 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 unpaid representative brought her its prestigious award.

Among her limited later feature films was the fantasy, Troll (1986) in which she portrayed a witch, with her own daughter, Anne Lockhart, playing her younger 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 union ended in divorce, as did her subsequent marriage, to John Lindsay, an designer.

She is survived by her daughters and four grandchildren.
