June Lockhart, who passed away at the remarkable age of 100, began her professional journey in films, but achieved fame after transitioning almost entirely to TV. Having been given few opportunities to excel in films from her debut as a youngster in 1938 until 1947, she thrived on television in numerous beloved series, especially in Lassie.

Her Memorable Role in Lassie

Stepping in from a previous star in 1958, Lockhart continued in the series until 1964. Her role was Ruth Martin, married to farmer Paul Martin and the foster mother of seven-year-old Timmy Martin, whose collie was the titular star of the series.

In her part as a housewife, Lockhart somehow succeeded to avoid being completely upstaged by the intelligent dog. She described the program 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 commercial”. After she departed the series, Lockhart commented: “In six chaste years of playing a rural wife and mother, I was rarely permitted to kiss my on-screen husband on the face.”

Journey into Lost in Space

Lockhart went directly into a second hit, 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 her co-star portrayed Maureen and John Robinson, two researchers investigating distant planets. Lockhart had to spend most of her time deftly trying to navigate visual effects. As the show continued, the narrative became less and less about this interstellar family and more about the young son and his friendship with a robot, 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 parts of her mother and father, Bob and Mrs Cratchit, were her actual parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canada-native Gene were both performers 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 tender age of six, came in a non-musical role in an musical production at the Metropolitan Opera in New York (1931).

Transition to Hollywood and Film Roles

When her father was offered a contract by a motion picture studio, after his acclaim on Broadway, she moved with her parents to Hollywood, where Gene made around 300 films. After attending school in Beverly Hills, June started her career in films, 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 charming as a New Yorker at a household party, whose schedule is filled spitefully to prevent Lockhart interacting with her brother.

More importantly, although she did not realize it at the time, was Son of Lassie (1945). It was one of several follow-ups to the extremely successful Lassie Come Home (1943), in which a young star had played the female character who assists the canine to return to the owners. In the subsequent film, Lockhart played the now grown-up version.

The loving way in which she interacted with both Lassie and her offspring, Laddie, hero of a wartime story in enemy-held Norway, was in the consideration of the creators when it came to selecting the Lassie TV series 13 years later.

TV 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 getting her nowhere and that TV would be the solution. Before going in a different direction, she won praise 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 doctor and maternal character. She also featured frequently in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy schedule persisted for the following 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 parent of a restaurant manager.

Final Roles and Achievements

Her last 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 starring well-known actors (1998), she had a holographic cameo as a school principal. She took joy in learning how much of an inspiration the original 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 Exceptional Public Achievement Medal.

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

Personal Details

In 1951 she wed John Maloney, a doctor 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 architect.

She is survived by her children and four grandkids.
