Launching her career in cinema, June Lockhart, who passed on aged 100, found her greatest success after switching largely to the small screen. Having been offered few chances to excel in movies from her debut as a youngster in 1938 until 1947, she excelled on television in numerous beloved series, most notably in Lassie.

Portraying Ruth Martin on 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 dog was the eponymous star of the series.

Even with playing a housewife, Lockhart skillfully avoided being overshadowed by the smart dog. She described the show 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 parent, I was rarely permitted to kiss my co-star on the cheek.”

Adventure into Lost in Space

Lockhart went directly into a second successful series, Lost in Space (1965-68), a semi-spoof science fiction series targeted primarily at children and based by The Swiss Family Robinson. Lockhart and her co-star portrayed Maureen and John Robinson, two scientists exploring distant planets. Lockhart had to spend most of her time deftly trying to survive visual effects. As the series progressed, the narrative became increasingly less about this space family and increasingly about the young son and his bond with a robot, and the timid antagonist Dr Zachary Smith.

Start in Show Business

Lockhart’s feature film 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 Canadian-born Gene were both actors in dozens of films, as well as on stage, it was nearly certain that June, who was born in New York, would join the entertainment industry.

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).

Move to Hollywood and Movie Roles

When her parent was given a deal by a motion picture studio, after his acclaim on Broadway, she relocated with her family 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 latter, she is charming as a New Yorker at a family party, whose dance card 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 multiple follow-ups to the hugely successful Lassie Come Home (1943), in which a young star had played the female character 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 wartime adventure in enemy-held Norway, was in the consideration of the creators when it came to casting the Lassie TV series 13 years later.

Transition to Television and Broadway Achievement

Although she was given major 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 TV would be the answer. Before going 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 substantial run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a physician and mother figure. She also appeared frequently in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy schedule continued for the following five decades, with a recurring role in General Hospital between 1984 and 1998. Among her many one-off appearances were as the actress in a 1988 episode of a talkshow, where the host finds a lost collie, and in another sitcom in 1995 as the parent of a dining manager.

Final Roles and Contributions

Her last TV credit came in 2021 as the narration of Alpha Control in an episode of a digital platform’s remake of Lost in Space. In the movie version featuring well-known actors (1998), she had a digital cameo as a school principal. She took pleasure in learning how much of an inspiration the first series had been to later astronauts, and often participated in the agency’s launches and other events. In 2013 her work as a volunteer representative brought her its prestigious award.

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

Personal Information

In 1951 she married John Maloney, a physician 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 architect.

She is survived by her daughters and four grandkids.
