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

June Lockhart, who died at the age of 100, started her professional journey in movies, but gained fame after moving almost entirely to TV. Having been given few chances to excel in films from her first appearance as a child in 1938 until 1947, she thrived on TV in many beloved series, most notably in Lassie.

Becoming Ruth Martin on Lassie

Taking over from another actress in 1958, Lockhart remained in the series until 1964. Her role was Ruth Martin, wed to farmer Paul Martin and the foster mother of young Timmy Martin, whose dog was the eponymous hero of the series.

In her part as a housewife, Lockhart somehow managed to avoid being completely overshadowed by the intelligent canine. She described the show as “a fairy tale about families on a rural property in which the canine resolves all the problems in 22 minutes, in time for the last commercial”. After she departed the series, Lockhart remarked: “In six chaste years of playing a country spouse and mother, I was hardly ever allowed to kiss my co-star on the cheek.”

Featuring in Lost in Space

Lockhart went straight into another successful series, 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 played Maureen and John Robinson, two researchers investigating distant planets. Lockhart had to spend the majority of her time skillfully trying to navigate special effects. As the series progressed, the storyline became increasingly less about this space clan and increasingly about the young son and his bond with a robot, and the cowardly villain Dr Zachary Smith.

Start in Show Business

Lockhart’s movie debut, at the age of 13, had come as Belinda Cratchit in A Christmas Carol (1938). In the parts of her parents, Bob and Mrs Cratchit, were her actual parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canada-native Gene were both performers in dozens of movies, as well as on stage, it was almost certain 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-singing role in an opera at the Metropolitan Opera in New York (1931).

Move to Hollywood and Movie Roles

When her parent was offered a deal by a motion picture studio, after his success on Broadway, she moved with her parents to Hollywood, where Gene made around 300 films. After going to school in Beverly Hills, June began her career in films, 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 latter, she is charming as a New Yorker at a family party, whose schedule is filled maliciously to prevent Lockhart interacting with her brother.

More importantly, 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 another actress had played the female character who assists the canine to escape to the family. In the later film, Lockhart played the now adult version.

The affectionate way in which she interacted with both Lassie and her offspring, Laddie, protagonist of a wartime story in enemy-held Norway, was in the minds of the creators when it came to selecting the Lassie TV series 13 years later.

Shift to Television and Broadway Achievement

Although she was offered leading roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her movie career was stagnating and that TV would be the answer. Before embarking in a different direction, she won acclaim on Broadway in For Love or Money (1947), a humorous play for which she won a Tony award as best newcomer.

A further significant run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a doctor and mother figure. She also featured regularly in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic schedule persisted for the next 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 stray collie, and in another sitcom in 1995 as the mother of a dining manager.

Later Career and Legacy

Her final 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 famous actors (1998), she had a holographic cameo as a school principal. She took pleasure in learning how much of an influence the first 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 limited subsequent feature films was the fantasy, Troll (1986) in which she played a witch, with her own daughter, Anne Lockhart, playing her earlier 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 divorce, as did her subsequent marriage, to John Lindsay, an designer.

She is survived by her daughters and four grandchildren.
