Starting her career in cinema, June Lockhart, who died aged 100, found her greatest success after shifting largely to television. Having been offered few chances to excel in movies from her debut as a child in 1938 until 1947, she thrived on television in many popular series, especially in Lassie.

Becoming Ruth Martin on Lassie

Stepping in from another actress in 1958, Lockhart continued in the show until 1964. She played Ruth Martin, married to farmer Paul Martin and the foster mother of young Timmy Martin, whose collie was the eponymous hero of the series.

Despite playing a housewife, Lockhart skillfully avoided being overshadowed by the brilliant animal star. She described the show as “a fairy tale about people on a farm in which the dog resolves all the problems in 22 minutes, in time for the last commercial”. After she departed the show, Lockhart commented: “In six sexless years of playing a country spouse and parent, I was rarely allowed to peck my on-screen husband on the cheek.”

Starring in Lost in Space

Lockhart went directly into another hit, Lost in Space (1965-68), a partly comedic science fiction series aimed mostly at young audiences and based by The Swiss Family Robinson. Lockhart and her co-star portrayed Maureen and John Robinson, two scientists investigating alien planets. Lockhart had to spend the majority of her time skillfully trying to survive special effects. As the series progressed, the narrative became less and less about this space family and increasingly about the young son and his bond with a robot, and the cowardly villain Dr Zachary Smith.

Beginnings in Show Business

Lockhart’s movie 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 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 stage, it was nearly inevitable that June, who was born in New York, would join show business.

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 parent was given a contract by a film studio, after his acclaim on Broadway, she relocated with her parents to Hollywood, where Gene made around 300 films. After attending school in Beverly Hills, June started her career in movies, 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 arranged maliciously to stop Lockhart dancing 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 another actress had played the girl who assists the canine to escape to the owners. In the subsequent film, Lockhart played the now adult character.

The affectionate 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 creators when it came to casting the Lassie TV series 13 years later.

TV and Theater Work

Although she was given major roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her film career was getting her nowhere and that TV would be the solution. Before going in a different direction, she won acclaim on Broadway in For Love or Money (1947), a humorous play for which she won a Tony award as best newcomer.

A additional significant run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a doctor and maternal character. She also appeared frequently in TV westerns 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 recurring role in General Hospital between 1984 and 1998. Among her many guest appearances were as the actress in a 1988 episode of a talkshow, where the host finds a stray collie, and in another sitcom in 1995 as the mother of a dining manager.

Later Roles and Achievements

Her final TV credit came in 2021 as the narration of Alpha Control in an episode of a streaming service’s new version of Lost in Space. In the big screen version starring famous actors (1998), she had a holographic cameo as a school principal. She took joy in learning how much of an inspiration the first series had been to later astronauts, and often attended the agency’s launches and other events. In 2013 her work as a unpaid representative brought her its prestigious award.

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

Personal Information

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

She is survived by her daughters and four grandkids.
