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

Starting her career in cinema, June Lockhart, who passed on aged 100, found her biggest success after switching predominantly to television. Having been offered limited opportunities to excel in films from her debut as a child in 1938 until 1947, she excelled on TV in many beloved series, especially in Lassie.

Becoming Ruth Martin on Lassie

Stepping in 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 seven-year-old Timmy Martin, whose collie was the eponymous star of the series.

Despite playing a mother figure, Lockhart skillfully avoided being outshone by the smart animal star. She characterized the show as “a fairy tale about families on a farm in which the canine resolves all the issues in 22 minutes, in time for the last advertisement”. After she departed the series, Lockhart commented: “In six chaste years of playing a country wife and parent, I was hardly ever permitted to kiss my co-star on the face.”

Journey into Lost in Space

Lockhart went straight into a second hit, Lost in Space (1965-68), a partly comedic sci-fi series aimed primarily at children and inspired by The Swiss Family Robinson. Lockhart and another actor portrayed Maureen and John Robinson, two scientists exploring distant planets. Lockhart had to spend the majority of her time skillfully trying to navigate special effects. As the show 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.

Initial Career and Family Influence

Lockhart’s feature film first role, at the young 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 actual parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canadian-born Gene were both actors in many of films, as well as on stage, it was almost certain that June, who was born in New York, would enter the entertainment industry.

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

Cinema Work

When her father was given a deal by a film studio, after his success on Broadway, she moved with her family to Hollywood, where Gene made around 300 films. After going to school in Beverly Hills, June started her career in movies, 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 arranged maliciously to prevent 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 multiple sequels to the hugely successful Lassie Come Home (1943), in which another actress had played the female character who assists the canine to return to the family. In the subsequent film, Lockhart played the now adult version.

The loving way in which she handled both Lassie and her son, Laddie, hero of a wartime story in enemy-held Norway, was in the minds of the creators when it came to selecting the Lassie TV series 13 years later.

Transition to Television and Broadway Success

Although she was given major roles in two suspense films, 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 answer. Before embarking in a different direction, she won acclaim on Broadway in For Love or Money (1947), a comedy for which she won a Tony award as most promising newcomer.

A additional significant run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a physician 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 hectic workload continued for the next five decades, with a recurring role in General Hospital between 1984 and 1998. Among her many guest appearances were as herself in a 1988 episode of a comedy series, 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 final TV appearance came in 2021 as the voice of Alpha Control in an episode of a digital platform’s remake 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 first 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 Exceptional Public Achievement Medal.

Among her limited subsequent feature films was the fantasy, Troll (1986) in which she played a witch, with her own daughter, Anne Lockhart, playing her younger 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 union ended in separation, as did her subsequent marriage, to John Lindsay, an architect.

She is remembered by her children and four grandchildren.
