June Lockhart: Celebrating the Iconic Star of Lassie and Lost in Space

Launching her career in films, June Lockhart, who passed on aged 100, achieved her greatest success after switching largely to television. Having been given few opportunities to excel in movies from her first appearance as a youngster in 1938 until 1947, she thrived on television in many beloved series, most notably in Lassie.

Her Iconic Role in Lassie

Stepping in from another actress in 1958, Lockhart continued in the show until 1964. Her role was Ruth Martin, married to agriculturalist Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose dog was the titular hero of the series.

Even with playing a mother figure, Lockhart skillfully avoided being overshadowed by the smart dog. She described the program as “a fantasy about people on a rural property in which the dog solves all the issues in 22 minutes, in time for the last commercial”. After she departed the show, Lockhart commented: “In six sexless years of playing a rural spouse and mother, I was rarely allowed to peck my co-star on the face.”

Featuring in Lost in Space

Lockhart went directly into a second hit, Lost in Space (1965-68), a semi-spoof sci-fi series targeted mostly at children and inspired by The Swiss Family Robinson. Lockhart and her co-star portrayed Maureen and John Robinson, two scientists exploring alien planets. Lockhart had to spend most of her time deftly trying to survive special effects. As the show continued, the storyline became less and less about this space clan and more 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 first role, 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 real-life parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canada-native Gene were both actors in dozens of films, as well as on theater, it was almost inevitable that June, who was born in New York, would join show business.

Her first theatrical 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).

Cinema Career

When her father was given a deal by a film studio, after his acclaim on Broadway, she relocated with her parents to Hollywood, where Gene made approximately 300 films. After attending school in Beverly Hills, June started her professional life 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 charming as a New Yorker at a household party, whose dance card is filled spitefully to stop Lockhart dancing with her brother.

More significantly, although she did not realize 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 girl who helps the canine to return to the owners. In the later film, Lockhart played the now adult version.

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

Shift to Television and Stage Achievement

Although she was offered major roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her film career was stagnating and that television would be the solution. Before going 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 best newcomer.

A further substantial run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a physician and maternal character. She also appeared regularly in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic workload persisted for the following five decades, with a regular role in General Hospital between 1984 and 1998. Among her many one-off 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 mother of a dining manager.

Later Roles and Contributions

Her last TV appearance came in 2021 as the narration of Alpha Control in an episode of a digital platform’s remake of Lost in Space. In the movie version featuring well-known 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 volunteer spokesperson brought her its Exceptional Public Achievement Medal.

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

Private Details

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

She is remembered by her daughters and four grandchildren.
