June Lockhart, who passed away at the remarkable age of 100, began her career in films, but gained recognition after transitioning almost exclusively to television. Having been given few opportunities to excel in movies from her debut as a youngster in 1938 until 1947, she excelled on TV in numerous beloved series, especially in Lassie.

Portraying Ruth Martin on Lassie

Taking over from another actress in 1958, Lockhart continued in the show until 1964. Her role was Ruth Martin, married to agriculturalist Paul Martin and the foster mother of young Timmy Martin, whose dog was the titular star of the series.

In her part as a housewife, Lockhart somehow managed to avoid being completely upstaged by the clever dog. She described the show as “a fantasy about people on a rural property in which the canine solves all the problems in 22 minutes, in time for the last advertisement”. After she left the series, Lockhart commented: “In six chaste years of playing a rural wife and mother, I was hardly ever permitted to peck my co-star on the face.”

Adventure into Lost in Space

Lockhart went directly into another hit, Lost in Space (1965-68), a semi-spoof sci-fi series aimed mostly at children and inspired by The Swiss Family Robinson. Lockhart and her co-star played Maureen and John Robinson, two researchers exploring alien planets. Lockhart had to spend most of her time skillfully trying to navigate visual effects. As the show progressed, the narrative became less and less about this interstellar clan and increasingly about the boy and his bond with a mechanical being, and the cowardly villain Dr Zachary Smith.

Early 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 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 actors in many of movies, as well as on stage, it was almost inevitable that June, who was born in New York, would enter the entertainment industry.

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

Move to Hollywood and Film Roles

When her parent was offered a contract by a motion picture studio, after his success on Broadway, she relocated 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 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 charming as a New Yorker at a household party, whose schedule is arranged spitefully to stop Lockhart interacting 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 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 grown-up character.

The affectionate way in which she interacted with both Lassie and her offspring, Laddie, hero of a World War II adventure in Nazi-occupied Norway, was in the consideration of the producers when it came to casting the Lassie TV series 13 years later.

TV and Stage Work

Although she was offered major roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her film career was stagnating and that TV would be the answer. Before going in a different direction, she received praise 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 rural hotel, where Lockhart is a doctor and maternal character. She also appeared 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 regular 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 presenter finds a lost collie, and in another sitcom in 1995 as the parent of a restaurant manager.

Later Roles and Contributions

Her last TV credit 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 starring well-known actors (1998), she had a holographic cameo as a school principal. She took pleasure in learning how much of an influence the original series had been to future astronauts, and often attended the organization’s launches and other events. In 2013 her work as a volunteer representative brought her its Exceptional Public Achievement Medal.

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

Private Information

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 separation, as did her second marriage, to John Lindsay, an architect.

She is remembered by her children and four grandkids.
