June Lockhart: Celebrating the Legendary 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 recognition after moving almost exclusively to TV. Having been offered few chances to excel in films from her debut as a child in 1938 until 1947, she thrived on television in numerous popular series, most notably in Lassie.

Portraying Ruth Martin on Lassie

Stepping in from a previous star in 1958, Lockhart continued in the show until 1964. She played Ruth Martin, wed to agriculturalist Paul Martin and the foster mother of young Timmy Martin, whose collie was the eponymous hero of the series.

Even with playing a mother figure, Lockhart skillfully avoided being overshadowed by the brilliant dog. She characterized the program as “a fantasy 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 remarked: “In six sexless years of playing a rural wife and mother, I was rarely permitted to peck my co-star on the cheek.”

Journey into Lost in Space

Lockhart went directly into another successful series, Lost in Space (1965-68), a partly comedic sci-fi series targeted primarily at young audiences and inspired by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two researchers exploring alien planets. Lockhart had to spend most of her time skillfully trying to survive visual effects. As the series progressed, the narrative became less and less about this interstellar family and more about the boy and his friendship with a robot, and the cowardly villain Dr Zachary Smith.

Initial Career and Family Background

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 mother and father, Bob and Mrs Cratchit, were her real-life parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canada-native Gene were both actors in many of movies, as well as on theater, it was almost inevitable that June, who was born in New York, would enter the entertainment industry.

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

Transition to Hollywood and Film Roles

When her father was offered a deal 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 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 last one, she is delightful as a New Yorker at a household party, whose dance card is filled spitefully to stop Lockhart dancing with her sibling.

More significantly, although she did not know 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 girl who assists the dog to return to the owners. In the later film, Lockhart played the now adult version.

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

Television and Stage Work

Although she was offered leading 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 solution. Before embarking 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 doctor and mother figure. She also appeared regularly in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic schedule persisted for the next five decades, with a recurring role in General Hospital between 1984 and 1998. Among her many one-off appearances were as herself in a 1988 episode of a talkshow, where the presenter finds a lost collie, and in another sitcom in 1995 as the parent of a dining manager.

Later Roles and Contributions

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

Among her few 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 Life and Family

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

She is remembered by her daughters and four grandchildren.
