Starting her career in films, June Lockhart, who passed on aged 100, achieved her biggest success after shifting predominantly to television. Having been offered few opportunities to shine in films from her debut as a child in 1938 until 1947, she thrived on television in many popular series, especially in Lassie.

Becoming Ruth Martin on Lassie

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

In her role as a housewife, Lockhart somehow succeeded to avoid being totally upstaged by the intelligent canine. She described the program as “a fairy tale about families on a rural property in which the canine solves all the problems in 22 minutes, in time for the last commercial”. After she left the show, Lockhart remarked: “In six chaste years of playing a country spouse and parent, I was rarely permitted 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 aimed 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 skillfully trying to survive special effects. As the series progressed, the storyline became less and less about this space clan and more about the young son and his friendship with a mechanical being, and the timid villain Dr Zachary Smith.

Early Career and Family Background

Lockhart’s movie first role, 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 UK-native Kathleen and Canadian-born Gene were both performers in dozens of movies, as well as on stage, it was nearly certain that June, who was born in New York, would join show business.

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

Move to Hollywood and Film Roles

When her parent was given a contract 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 movies, mainly 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 delightful as a New Yorker at a household party, whose dance card is arranged maliciously to prevent 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 multiple follow-ups to the hugely successful Lassie Come Home (1943), in which another actress had played the girl who helps the dog to return to the owners. In the later film, Lockhart played the now grown-up character.

The affectionate way in which she handled 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 selecting the Lassie TV series 13 years later.

Shift to Television and Broadway Success

Although she was offered leading roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her film career was getting her nowhere and that television would be the solution. Before embarking 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 best newcomer.

A additional significant run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a doctor and mother figure. She also featured frequently in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic 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 host finds a lost collie, and in another sitcom in 1995 as the mother of a dining manager.

Final Career and Impact

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 movie 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 first series had been to future astronauts, and often participated in the organization’s launches and other events. In 2013 her work as a volunteer spokesperson brought her its Exceptional Public Achievement Medal.

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

Private Details

In 1951 she married John Maloney, a doctor and former Navy doctor. In addition to Anne, they had a second daughter, June. That union ended in divorce, as did her subsequent marriage, to John Lindsay, an designer.

She is remembered by her daughters and four grandkids.
