June Lockhart: A Lifetime of Television Success from Lassie to Lost in Space

Launching her career in films, June Lockhart, who died aged 100, achieved her greatest success after shifting predominantly to the small screen. Having been given few opportunities to excel in movies from her debut as a child in 1938 until 1947, she excelled on television in many beloved series, most notably in Lassie.

Her Memorable Role in Lassie

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

Even with playing a housewife, Lockhart adeptly avoided being outshone by the smart dog. She described the program as “a fantasy about people on a farm in which the dog resolves all the issues in 22 minutes, in time for the last advertisement”. After she left the series, Lockhart remarked: “In six sexless years of playing a rural wife and parent, I was rarely permitted to kiss my co-star on the cheek.”

Starring in Lost in Space

Lockhart went directly into a second hit, Lost in Space (1965-68), a partly comedic sci-fi series targeted primarily at young audiences and inspired by The Swiss Family Robinson. Lockhart and her co-star portrayed Maureen and John Robinson, two scientists investigating alien planets. Lockhart had to spend the majority of her time skillfully trying to navigate visual effects. As the show progressed, the narrative became increasingly 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 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 actual parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canada-native Gene were both actors in dozens of movies, as well as on theater, it was nearly 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).

Transition to Hollywood and Movie Roles

When her parent was offered a deal by a film studio, after his success on Broadway, she moved with her parents to Hollywood, where Gene made around 300 films. After attending school in Beverly Hills, June began her professional life 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 last one, she is delightful as a New Yorker at a family party, whose schedule is filled maliciously to stop Lockhart dancing with her brother.

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

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

Shift to Television and Broadway Success

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

A further significant run came with Petticoat Junction (1968-70), set in a country 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 busy workload continued for the following 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 parent of a dining manager.

Later Career and Impact

Her final TV appearance came in 2021 as the voice of Alpha Control in an episode of a streaming service’s remake of Lost in Space. In the movie 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 original series had been to future astronauts, and often attended the agency’s launches and other events. In 2013 her work as a unpaid representative brought her its prestigious award.

Among her few 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 Life and Family

In 1951 she wed John Maloney, a doctor and former Navy doctor. 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 survived by her daughters and four grandkids.
