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

Launching her career in cinema, June Lockhart, who died aged 100, achieved her greatest success after switching predominantly to the small screen. Having been offered limited chances to excel in movies from her first appearance as a child in 1938 until 1947, she excelled on television in numerous beloved series, most notably in Lassie.

Becoming Ruth Martin on Lassie

Stepping in from another actress in 1958, Lockhart remained in the series until 1964. Her role was Ruth Martin, married to agriculturalist Paul Martin and the adoptive mother of young Timmy Martin, whose dog was the eponymous hero of the series.

In her part as a homemaker, Lockhart somehow succeeded to avoid being completely overshadowed by the clever canine. She described 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 advertisement”. After she departed the show, Lockhart commented: “In six chaste years of playing a rural spouse and parent, I was rarely allowed to peck my co-star on the face.”

Starring in Lost in Space

Lockhart went directly into another hit, Lost in Space (1965-68), a partly comedic science fiction series aimed mostly at children and based by The Swiss Family Robinson. Lockhart and her co-star portrayed Maureen and John Robinson, two scientists exploring distant planets. Lockhart had to spend most of her time deftly trying to survive special effects. As the show progressed, the narrative became increasingly less about this space family and more about the young son and his friendship with a mechanical being, and the timid villain Dr Zachary Smith.

Beginnings in Entertainment

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 actual parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canadian-born Gene were both actors in many 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 appearance, at the age of six, came in a non-musical role in an musical production at the Metropolitan Opera in New York (1931).

Hollywood Career

When her parent was given a contract by a film studio, after his acclaim on Broadway, she moved with her family to Hollywood, where Gene made approximately 300 films. After going to school in Beverly Hills, June started her career in films, mostly 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 last one, she is delightful as a New Yorker at a family party, whose dance card is arranged spitefully to prevent Lockhart interacting with her sibling.

More importantly, although she did not realize it at the time, was Son of Lassie (1945). It was one of multiple follow-ups to the extremely successful Lassie Come Home (1943), in which a young star had played the girl who assists the canine to return to the owners. In the later film, Lockhart played the now grown-up version.

The affectionate way in which she interacted with both Lassie and her offspring, Laddie, hero of a wartime 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 given leading roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her film career was stagnating and that TV would be the answer. Before embarking 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 most promising newcomer.

A further significant run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a physician and maternal character. She also appeared frequently in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy workload continued for the following five decades, with a recurring 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 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 voice of Alpha Control in an episode of a digital platform’s new version 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 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 spokesperson brought her its prestigious award.

Among her limited subsequent feature films was the fantasy, Troll (1986) in which she portrayed a sorceress, 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 marriage ended in divorce, as did her second marriage, to John Lindsay, an architect.

She is remembered by her children and four grandchildren.
