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

Starting her career in films, June Lockhart, who died aged 100, achieved her greatest success after switching largely to the small screen. Having been offered few opportunities to shine in movies from her debut as a child in 1938 until 1947, she thrived on TV in many beloved series, most notably in Lassie.

Portraying Ruth Martin on Lassie

Taking over from another actress in 1958, Lockhart remained in the show until 1964. Her role was Ruth Martin, married to agriculturalist Paul Martin and the adoptive mother of young Timmy Martin, whose dog was the eponymous hero of the series.

Despite playing a housewife, Lockhart adeptly avoided being outshone by the brilliant dog. She characterized the show as “a fantasy about people on a rural property in which the dog resolves all the problems in 22 minutes, in time for the last commercial”. After she left the show, Lockhart remarked: “In six sexless years of playing a rural wife and parent, I was rarely allowed to kiss my co-star on the face.”

Starring in Lost in Space

Lockhart went directly into another successful series, Lost in Space (1965-68), a partly comedic science fiction series aimed mostly 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 skillfully trying to navigate visual effects. As the show progressed, the narrative became increasingly less about this interstellar family and increasingly about the young son and his friendship with a mechanical being, and the cowardly antagonist Dr Zachary Smith.

Beginnings in Entertainment

Lockhart’s feature film debut, at the young age of 13, had come as Belinda Cratchit in A Christmas Carol (1938). In the roles 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 performers in dozens of films, as well as on stage, it was nearly certain that June, who was born in New York, would join show business.

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

Move to Hollywood and Movie Roles

When her parent was offered a contract by a motion picture studio, after his success on Broadway, she relocated with her parents to Hollywood, where Gene made approximately 300 films. After attending school in Beverly Hills, June started her professional life in movies, mostly 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 charming as a New Yorker at a household party, whose schedule is arranged spitefully to prevent Lockhart interacting 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 extremely successful Lassie Come Home (1943), in which a young star had played the female character who assists the canine to return to the family. In the later film, Lockhart played the now adult character.

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

TV and Theater Career

Although she was offered 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 embarking in a different direction, she won praise on Broadway in For Love or Money (1947), a humorous play for which she won a Tony award as most promising newcomer.

A further significant run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a physician and mother figure. She also featured frequently in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic workload persisted 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 comedy series, where the host finds a lost collie, and in another sitcom in 1995 as the parent of a restaurant manager.

Final Roles and Achievements

Her final TV credit came in 2021 as the narration of Alpha Control in an episode of a streaming service’s remake of Lost in Space. In the big screen version featuring famous actors (1998), she had a digital 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 spokesperson brought her its prestigious award.

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

She is remembered by her children and four grandchildren.
