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

Starting her career in cinema, June Lockhart, who died aged 100, found her biggest success after shifting predominantly to television. Having been offered few opportunities to excel in films from her debut as a child in 1938 until 1947, she thrived on television in numerous beloved series, especially in Lassie.

Her Memorable Role in Lassie

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

Even with playing a mother figure, Lockhart adeptly avoided being outshone by the brilliant dog. She characterized the program as “a fantasy about families on a farm in which the canine solves all the issues in 22 minutes, in time for the last commercial”. After she left the show, Lockhart remarked: “In six sexless years of playing a country spouse and mother, I was hardly ever permitted to peck my co-star on the cheek.”

Featuring in Lost in Space

Lockhart went straight into another successful series, Lost in Space (1965-68), a semi-spoof sci-fi series aimed mostly at children and based by The Swiss Family Robinson. Lockhart and another actor portrayed Maureen and John Robinson, two researchers exploring distant planets. Lockhart had to spend most of her time deftly trying to survive special effects. As the series progressed, the storyline became increasingly less about this interstellar family and increasingly about the boy and his bond with a robot, and the timid antagonist Dr Zachary Smith.

Early 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 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 actors in dozens of films, as well as on stage, it was almost certain that June, who was born in New York, would enter show business.

Her first stage appearance, at the tender 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 relocated with her family to Hollywood, where Gene made around 300 films. After going to school in Beverly Hills, June began 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 dance card is arranged maliciously 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 extremely successful Lassie Come Home (1943), in which another actress had played the female character who assists the dog to return to the owners. In the later film, Lockhart played the now grown-up character.

The affectionate way in which she handled both Lassie and her offspring, Laddie, hero of a World War II story in Nazi-occupied Norway, was in the minds of the producers when it came to selecting the Lassie TV series 13 years later.

Transition to Television and Broadway Achievement

Although she was offered leading roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her film career was getting her nowhere and that television would be the answer. Before going in a different direction, she received 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 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 hectic workload 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 comedy series, where the host finds a lost collie, and in another sitcom in 1995 as the mother of a restaurant manager.

Final Career and Impact

Her last 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 movie version featuring well-known actors (1998), she had a digital 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 attended the organization’s launches and other events. In 2013 her work as a volunteer representative brought her its prestigious award.

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

Private Details

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

She is survived by her daughters and four grandchildren.
