Starting her career in cinema, June Lockhart, who died aged 100, achieved her greatest success after switching predominantly to television. Having been given few opportunities to shine in films from her debut as a child in 1938 until 1947, she thrived on TV in many popular series, most notably in Lassie.

Her Iconic Role in Lassie

Taking over from another actress in 1958, Lockhart continued in the series until 1964. Her role was Ruth Martin, wed to farmer Paul Martin and the adoptive 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 canine. She described the program as “a fairy tale about people on a farm in which the canine resolves all the problems in 22 minutes, in time for the last advertisement”. After she departed the show, Lockhart commented: “In six chaste years of playing a country spouse and mother, I was hardly ever allowed to peck my co-star on the face.”

Adventure into Lost in Space

Lockhart went directly into another hit, Lost in Space (1965-68), a partly comedic science fiction series aimed primarily at young audiences and based 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 deftly trying to survive special effects. As the series progressed, the storyline became less and less about this space family and increasingly about the young son and his friendship with a robot, and the timid antagonist Dr Zachary Smith.

Initial 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 performers in dozens of movies, as well as on theater, it was nearly inevitable that June, who was born in New York, would enter show business.

Her first stage performance, at the age of six, came in a non-singing role in an opera at the Metropolitan Opera in New York (1931).

Hollywood Career

When her father was offered a contract by a film studio, after his acclaim on Broadway, she relocated with her parents to Hollywood, where Gene made approximately 300 films. After attending school in Beverly Hills, June started her career in movies, 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 latter, she is charming as a New Yorker at a family party, whose dance card is arranged maliciously to stop Lockhart dancing with her brother.

More significantly, 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 another actress had played the girl who helps the canine to return to the family. In the subsequent film, Lockhart played the now adult character.

The loving way in which she interacted with both Lassie and her son, Laddie, hero of a World War II adventure in Nazi-occupied Norway, was in the consideration of the creators when it came to selecting the Lassie TV series 13 years later.

Transition to Television and Stage Achievement

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

A further substantial run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a doctor and mother figure. She also featured regularly in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy workload continued for the next five decades, with a regular role in General Hospital between 1984 and 1998. Among her many guest appearances were as herself in a 1988 episode of a talkshow, where the presenter finds a stray collie, and in another sitcom in 1995 as the mother of a dining manager.

Final Roles and Achievements

Her last TV appearance came in 2021 as the narration of Alpha Control in an episode of a digital platform’s remake of Lost in Space. In the big screen version featuring famous actors (1998), she had a holographic cameo as a school principal. She took joy in learning how much of an inspiration the first series had been to future astronauts, and often attended the agency’s launches and other events. In 2013 her work as a volunteer spokesperson brought her its Exceptional Public Achievement Medal.

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

Private Details

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

She is remembered by her children and four grandkids.
