June Lockhart, who passed away at the age of 100, started her professional journey in movies, but achieved recognition after transitioning almost exclusively to TV. Having been given few opportunities to shine in movies from her debut as a child in 1938 until 1947, she thrived on TV in numerous 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, married to agriculturalist Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose collie was the titular hero of the series.

In her role as a housewife, Lockhart somehow managed to avoid being completely upstaged by the clever canine. She described the show as “a fantasy about families on a farm 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 country wife and mother, I was hardly ever permitted to peck my co-star on the face.”

Featuring in Lost in Space

Lockhart went straight into another successful series, Lost in Space (1965-68), a semi-spoof science fiction series aimed primarily at young audiences and based by The Swiss Family Robinson. Lockhart and her co-star portrayed Maureen and John Robinson, two scientists exploring alien planets. Lockhart had to spend most of her time deftly trying to survive special effects. As the series continued, the storyline became less and less about this interstellar clan and increasingly about the boy and his friendship with a mechanical being, and the timid antagonist Dr Zachary Smith.

Initial Career and Family Background

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 real-life parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canadian-born Gene were both actors in dozens of films, as well as on stage, it was almost certain that June, who was born in New York, would join the entertainment industry.

Her first stage 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 deal by a film studio, after his success on Broadway, she moved with her parents to Hollywood, where Gene made approximately 300 films. After going to school in Beverly Hills, June began her career in movies, 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 last one, she is delightful as a New Yorker at a household party, whose schedule is filled spitefully to stop Lockhart interacting with her sibling.

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 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 subsequent film, Lockhart played the now adult version.

The affectionate way in which she handled both Lassie and her offspring, Laddie, protagonist of a World War II story in enemy-held Norway, was in the minds of the producers when it came to casting the Lassie TV series 13 years later.

Television and Stage Career

Although she was given leading roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her film career was stagnating and that TV would be the solution. Before going 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 best newcomer.

A further substantial run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a doctor and mother figure. She also featured frequently in TV westerns 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 guest appearances were as herself in a 1988 episode of a comedy series, where the presenter finds a lost collie, and in another sitcom in 1995 as the parent of a dining manager.

Final Roles and Achievements

Her final TV appearance 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 starring famous actors (1998), she had a digital cameo as a school principal. She took joy in learning how much of an inspiration 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 unpaid representative brought her its prestigious award.

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.

Personal Life and Family

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

She is remembered by her children and four grandkids.
