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

Starting her career in cinema, June Lockhart, who passed on aged 100, found her biggest success after shifting predominantly to television. Having been given limited opportunities to excel in films from her debut as a child in 1938 until 1947, she thrived on TV in numerous popular series, especially in Lassie.

Her Iconic Role in Lassie

Taking over from a previous star in 1958, Lockhart remained in the show until 1964. She played Ruth Martin, wed to agriculturalist Paul Martin and the foster mother of seven-year-old Timmy Martin, whose dog was the titular hero of the series.

In her role as a homemaker, Lockhart somehow managed to avoid being completely upstaged by the clever canine. She described the program as “a fairy tale about people on a farm in which the canine resolves all the issues in 22 minutes, in time for the last commercial”. After she departed the series, Lockhart commented: “In six sexless years of playing a rural wife and parent, I was rarely allowed to peck my co-star on the face.”

Starring in Lost in Space

Lockhart went directly into another successful series, Lost in Space (1965-68), a partly comedic sci-fi series targeted mostly at children and based by The Swiss Family Robinson. Lockhart and another actor portrayed Maureen and John Robinson, two researchers investigating distant planets. Lockhart had to spend the majority of her time deftly trying to navigate visual effects. As the show continued, the storyline became less and less about this space clan and more about the boy and his friendship with a robot, and the timid antagonist Dr Zachary Smith.

Initial Career and Family Background

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 Canadian-born Gene were both performers in dozens of movies, as well as on theater, it was almost inevitable that June, who was born in New York, would enter show business.

Her first stage performance, 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 offered a deal 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 professional life in films, mostly 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 latter, she is delightful as a New Yorker at a household party, whose dance card is filled maliciously 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 multiple follow-ups to the hugely successful Lassie Come Home (1943), in which another actress had played the girl who assists the dog to escape to the family. In the subsequent film, Lockhart played the now grown-up version.

The loving way in which she interacted with both Lassie and her son, Laddie, protagonist of a World War II adventure in enemy-held Norway, was in the minds of the creators when it came to casting the Lassie TV series 13 years later.

Shift to Television and Stage Success

Although she was offered leading roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her movie career was getting her nowhere and that TV would be the solution. Before embarking in a different 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 country hotel, where Lockhart is a doctor and maternal character. She also featured frequently in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic schedule continued for the following 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 dining manager.

Later Career and Impact

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 pleasure 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 spokesperson brought her its prestigious award.

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

Personal Life and Family

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

She is survived by her children and four grandchildren.
