June Lockhart, who died at the remarkable age of 100, began her career in movies, but achieved recognition after moving almost exclusively to TV. Having been offered limited opportunities to excel in films from her debut as a child in 1938 until 1947, she thrived on TV in many beloved series, especially in Lassie.

Becoming Ruth Martin on Lassie

Taking over from another actress in 1958, Lockhart remained in the series until 1964. She played Ruth Martin, married to farmer Paul Martin and the foster mother of young Timmy Martin, whose dog was the titular star of the series.

Despite playing a housewife, Lockhart skillfully avoided being outshone by the brilliant dog. She characterized the show as “a fairy tale about people on a farm in which the dog resolves all the issues in 22 minutes, in time for the last advertisement”. After she left the series, Lockhart remarked: “In six sexless years of playing a country spouse and mother, I was hardly ever permitted to kiss my on-screen husband on the face.”

Journey into Lost in Space

Lockhart went straight into a second successful series, Lost in Space (1965-68), a semi-spoof sci-fi series targeted primarily at young audiences and inspired by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two scientists investigating alien planets. Lockhart had to spend most of her time skillfully trying to survive visual effects. As the series progressed, the storyline became less and less about this interstellar clan and more about the young son and his friendship with a mechanical being, and the timid villain Dr Zachary Smith.

Early Career and Family Influence

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 parents, Bob and Mrs Cratchit, were her actual 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 join show business.

Her first stage appearance, at the tender age of six, came in a non-singing role in an opera at the Metropolitan Opera in New York (1931).

Hollywood Career

When her parent was offered a deal by a motion picture studio, after his success on Broadway, she relocated with her family to Hollywood, where Gene made approximately 300 films. After attending school in Beverly Hills, June started her professional life in movies, 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 schedule is filled maliciously to prevent Lockhart dancing with her brother.

More importantly, although she did not realize it at the time, was Son of Lassie (1945). It was one of multiple sequels to the extremely successful Lassie Come Home (1943), in which another actress had played the female character who assists the canine to return to the owners. In the later film, Lockhart played the now grown-up character.

The affectionate way in which she handled both Lassie and her son, Laddie, protagonist of a wartime adventure in enemy-held Norway, was in the consideration of the producers when it came to casting the Lassie TV series 13 years later.

Television and Stage Work

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 stagnating and that television would be the solution. 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 significant run came with Petticoat Junction (1968-70), set in a country 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 workload persisted for the next 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 lost collie, and in another sitcom in 1995 as the mother of a restaurant manager.

Final Career and Legacy

Her last TV credit came in 2021 as the narration of Alpha Control in an episode of a digital platform’s new version of Lost in Space. In the big screen version featuring famous actors (1998), she had a digital cameo as a school principal. She took pleasure in learning how much of an inspiration 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 unpaid representative brought her its prestigious award.

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

Personal Life and Family

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

She is remembered by her daughters and four grandchildren.
