June Lockhart: Remembering the Iconic Star of Lassie and Lost in Space

June Lockhart, who passed away at the remarkable age of 100, began her career in movies, but gained fame after transitioning almost exclusively to television. Having been given limited opportunities to excel in films from her debut as a child in 1938 until 1947, she excelled on television in numerous popular series, especially in Lassie.

Her Memorable Role in Lassie

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

In her role as a homemaker, Lockhart somehow managed to avoid being totally overshadowed by the intelligent dog. She characterized the show as “a fairy tale about families on a rural property in which the dog resolves all the problems in 22 minutes, in time for the last advertisement”. After she departed the series, Lockhart commented: “In six sexless years of playing a rural spouse and mother, I was hardly ever permitted to peck my on-screen husband on the face.”

Starring in Lost in Space

Lockhart went straight into a second successful series, Lost in Space (1965-68), a semi-spoof sci-fi series aimed primarily at children and inspired by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two scientists exploring alien planets. Lockhart had to spend the majority of her time skillfully trying to navigate special effects. As the series continued, the narrative became less and less about this space family and more about the boy and his bond with a robot, and the cowardly villain Dr Zachary Smith.

Initial Career and Family Background

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 British-born Kathleen and Canada-native Gene were both performers in many of movies, as well as on stage, it was almost inevitable that June, who was born in New York, would enter show business.

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

Transition to Hollywood and Movie Roles

When her father was given a deal by a film studio, after his success on Broadway, she relocated with her parents to Hollywood, where Gene made around 300 films. After attending school in Beverly Hills, June began her professional life in films, 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 latter, she is delightful as a New Yorker at a family party, whose schedule is arranged spitefully to prevent Lockhart interacting 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 extremely successful Lassie Come Home (1943), in which another actress had played the girl who helps the canine to escape 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, protagonist 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 Success

Although she was given leading roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her film career was stagnating and that TV would be the answer. Before going in a different direction, she received acclaim 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 maternal character. She also featured frequently in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy workload continued for the following five decades, with a regular 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 presenter finds a lost collie, and in another sitcom in 1995 as the mother of a restaurant manager.

Later Roles and Achievements

Her final TV appearance came in 2021 as the voice of Alpha Control in an episode of a streaming service’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 original series had been to future astronauts, and often participated in the organization’s launches and other events. In 2013 her work as a unpaid representative brought her its prestigious award.

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

Private Details

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 remembered by her daughters and four grandchildren.
