June Lockhart, who passed away at the age of 100, started her professional journey in films, but achieved recognition after transitioning almost exclusively to television. Having been given few opportunities to excel in films from her debut as a child in 1938 until 1947, she excelled on television in many beloved series, especially in Lassie.

Her Iconic Role in Lassie

Stepping in from a previous star in 1958, Lockhart continued in the series until 1964. Her role was Ruth Martin, wed to agriculturalist Paul Martin and the foster mother of seven-year-old Timmy Martin, whose collie was the eponymous hero of the series.

Even with playing a housewife, Lockhart skillfully avoided being overshadowed by the brilliant animal star. She characterized the show as “a fantasy about people on a farm in which the canine solves all the issues in 22 minutes, in time for the last commercial”. After she departed the series, Lockhart remarked: “In six chaste years of playing a country spouse and mother, I was hardly ever permitted to kiss my on-screen husband on the cheek.”

Journey into Lost in Space

Lockhart went directly into a second successful series, Lost in Space (1965-68), a partly comedic sci-fi series targeted mostly at children and based by The Swiss Family Robinson. Lockhart and another actor portrayed Maureen and John Robinson, two researchers exploring alien planets. Lockhart had to spend the majority of her time deftly trying to survive special effects. As the show progressed, the narrative became increasingly less about this space family and more about the boy and his friendship with a robot, and the timid villain Dr Zachary Smith.

Start in Entertainment

Lockhart’s feature film debut, at the 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 British-born Kathleen and Canada-native Gene were both performers in dozens 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 stage appearance, at the tender age of six, came in a non-musical role in an opera at the Metropolitan Opera in New York (1931).

Hollywood Work

When her father was given a contract by a motion picture studio, after his acclaim on Broadway, she moved with her family to Hollywood, where Gene made around 300 films. After going to school in Beverly Hills, June began her career in movies, mostly in small 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 charming as a New Yorker at a household party, whose dance card is filled maliciously to stop Lockhart interacting with her brother.

More importantly, although she did not realize it at the time, was Son of Lassie (1945). It was one of multiple sequels to the extremely successful Lassie Come Home (1943), in which a young star had played the female character who helps the canine to escape to the family. In the later film, Lockhart played the now grown-up version.

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

Transition to Television and Broadway Success

Although she was offered major roles in two suspense films, 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 solution. 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 most promising newcomer.

A further significant run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a doctor and mother figure. She also appeared 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 herself 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 restaurant manager.

Later Roles and Achievements

Her last TV appearance came in 2021 as the narration of Alpha Control in an episode of a digital platform’s new version of Lost in Space. In the movie version featuring famous actors (1998), she had a holographic cameo as a school principal. She took pleasure in learning how much of an influence the original series had been to later astronauts, and often attended the organization’s launches and other events. In 2013 her work as a volunteer representative brought her its prestigious award.

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

Personal Life and Family

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

She is remembered by her children and four grandchildren.
