June Lockhart, who died at the remarkable age of 100, began her professional journey in films, but gained recognition after transitioning almost exclusively to TV. Having been offered limited opportunities to shine in films from her first appearance as a child in 1938 until 1947, she thrived on television in numerous beloved series, most notably in Lassie.

Portraying Ruth Martin on Lassie

Taking over from a previous star 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 eponymous hero of the series.

In her part as a housewife, Lockhart somehow managed to avoid being totally upstaged by the clever dog. She characterized the show as “a fairy tale about people on a rural property in which the canine solves all the issues in 22 minutes, in time for the last commercial”. After she departed the show, Lockhart remarked: “In six sexless years of playing a rural spouse and mother, I was hardly ever allowed to kiss my co-star on the face.”

Adventure into Lost in Space

Lockhart went straight into a second successful series, Lost in Space (1965-68), a semi-spoof science fiction series targeted primarily at young audiences and inspired by The Swiss Family Robinson. Lockhart and another actor portrayed Maureen and John Robinson, two researchers exploring distant planets. Lockhart had to spend most of her time deftly trying to survive visual effects. As the series continued, the storyline became increasingly less about this interstellar clan and more about the young son and his friendship with a robot, and the timid antagonist Dr Zachary Smith.

Start in Entertainment

Lockhart’s feature film debut, at the young age of 13, had come as Belinda Cratchit in A Christmas Carol (1938). In the roles of her mother and father, Bob and Mrs Cratchit, were her real-life parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canadian-born Gene were both performers in dozens of movies, as well as on stage, it was nearly inevitable that June, who was born in New York, would enter the entertainment industry.

Her first theatrical appearance, 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 motion picture studio, after his acclaim on Broadway, she moved with her parents to Hollywood, where Gene made approximately 300 films. After attending school in Beverly Hills, June started her career in films, mainly in minor 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 schedule 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 sequels 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 character.

The affectionate way in which she handled both Lassie and her son, 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.

Transition to Television and Broadway Achievement

Although she was offered leading roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her film career was stagnating and that television would be the answer. Before embarking in a new direction, she won acclaim on Broadway in For Love or Money (1947), a comedy for which she won a Tony award as most promising newcomer.

A additional substantial run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a physician and maternal character. 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 continued 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 restaurant manager.

Later Career and Legacy

Her final TV appearance came in 2021 as the narration of Alpha Control in an episode of a streaming service’s new version 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 inspiration the original series had been to later 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 few later feature films was the fantasy, Troll (1986) in which she portrayed a sorceress, with her own daughter, Anne Lockhart, playing her younger self.

Personal Life and Family

In 1951 she married 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 second marriage, to John Lindsay, an designer.

She is survived by her children and four grandchildren.
