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

Her Iconic Role in Lassie

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

In her role as a homemaker, Lockhart somehow succeeded to avoid being completely overshadowed by the intelligent dog. She characterized the show as “a fantasy about families on a farm in which the canine resolves all the issues in 22 minutes, in time for the last commercial”. After she left the series, Lockhart commented: “In six chaste years of playing a rural wife and parent, I was rarely allowed to kiss my co-star on the face.”

Featuring in Lost in Space

Lockhart went straight into a second successful series, Lost in Space (1965-68), a semi-spoof science fiction series targeted mostly at young audiences and inspired by The Swiss Family Robinson. Lockhart and her co-star played Maureen and John Robinson, two researchers investigating alien planets. Lockhart had to spend the majority of her time skillfully trying to navigate special effects. As the series continued, the storyline became increasingly less about this space clan and increasingly about the young son and his bond with a mechanical being, and the timid villain Dr Zachary Smith.

Beginnings in Show Business

Lockhart’s movie debut, at the age of 13, had come as Belinda Cratchit in A Christmas Carol (1938). In the parts of her parents, Bob and Mrs Cratchit, were her real-life parents, Gene and Kathleen Lockhart. As British-born 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 show business.

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

Hollywood Career

When her parent was offered a contract by a film studio, after his acclaim on Broadway, she moved with her parents to Hollywood, where Gene made around 300 films. After going to school in Beverly Hills, June began her career in films, mainly 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 family party, whose dance card is arranged spitefully to stop Lockhart dancing 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 hugely successful Lassie Come Home (1943), in which a young star had played the female character who helps the canine to escape to the owners. In the subsequent film, Lockhart played the now adult version.

The loving way in which she interacted with 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 selecting the Lassie TV series 13 years later.

Shift to Television and Stage Success

Although she was offered major roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her film career was stagnating and that television would be the solution. Before going in a new direction, she received praise on Broadway in For Love or Money (1947), a humorous play for which she won a Tony award as best newcomer.

A additional 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 busy schedule continued for the next five decades, with a regular role in General Hospital between 1984 and 1998. Among her many guest appearances were as the actress in a 1988 episode of a comedy series, where the presenter finds a lost collie, and in another sitcom in 1995 as the mother of a dining manager.

Later Career and Legacy

Her final TV appearance came in 2021 as the voice of Alpha Control in an episode of a streaming service’s new version of Lost in Space. In the big screen version featuring well-known actors (1998), she had a digital 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 agency’s launches and other events. In 2013 her work as a unpaid representative brought her its prestigious award.

Among her limited later 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 wed John Maloney, a physician and former Navy medical officer. In addition to Anne, they had a second daughter, June. That marriage ended in separation, as did her second marriage, to John Lindsay, an architect.

She is remembered by her daughters and four grandkids.
