June Lockhart, who passed away at the remarkable age of 100, began her career in movies, but gained fame after moving almost exclusively to TV. Having been offered limited chances to shine in movies from her debut as a youngster in 1938 until 1947, she thrived on television in numerous popular series, especially in Lassie.

Her Memorable Role in Lassie

Taking over from a previous star in 1958, Lockhart remained in the show until 1964. Her role was Ruth Martin, wed to farmer Paul Martin and the adoptive mother of young Timmy Martin, whose collie was the titular star of the series.

Even with playing a mother figure, Lockhart adeptly avoided being outshone by the smart animal star. She characterized the program as “a fairy tale about people on a farm in which the dog solves all the issues in 22 minutes, in time for the last commercial”. After she departed the series, Lockhart remarked: “In six sexless years of playing a rural wife and mother, I was hardly ever allowed to peck my co-star on the face.”

Journey into Lost in Space

Lockhart went directly into another successful series, Lost in Space (1965-68), a partly comedic sci-fi series targeted primarily at young audiences and based by The Swiss Family Robinson. Lockhart and her co-star portrayed Maureen and John Robinson, two scientists investigating distant planets. Lockhart had to spend most of her time deftly trying to navigate visual effects. As the show progressed, the storyline became increasingly less about this interstellar clan and increasingly about the boy and his friendship with a robot, and the timid antagonist Dr Zachary Smith.

Initial 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 mother and father, Bob and Mrs Cratchit, were her real-life parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canadian-born Gene were both performers in dozens of films, as well as on theater, it was almost inevitable 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).

Cinema Work

When her father was offered a contract by a film studio, after his acclaim on Broadway, she relocated with her family to Hollywood, where Gene made around 300 films. After attending school in Beverly Hills, June began 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 importantly, although she did not realize it at the time, was Son of Lassie (1945). It was one of several sequels to the hugely successful Lassie Come Home (1943), in which another actress had played the girl who assists the canine to escape to the family. In the later film, Lockhart played the now grown-up character.

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

Television and Stage Career

Although she was offered leading roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her movie career was stagnating and that TV would be the answer. Before embarking in a new direction, she won 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 rural hotel, where Lockhart is a physician 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 workload 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 herself in a 1988 episode of a comedy series, where the host finds a lost collie, and in another sitcom in 1995 as the parent of a dining manager.

Later Roles and Contributions

Her final TV credit came in 2021 as the voice of Alpha Control in an episode of a streaming service’s remake of Lost in Space. In the big screen version starring famous actors (1998), she had a holographic cameo as a school principal. She took joy in learning how much of an influence the first series had been to later 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 portrayed 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 marriage ended in divorce, as did her second marriage, to John Lindsay, an architect.

She is survived by her daughters and four grandkids.
