June Lockhart, who passed away at the age of 100, started her professional journey in films, but achieved fame after transitioning almost exclusively to TV. Having been given limited opportunities to excel in films from her debut as a child in 1938 until 1947, she thrived on television in many popular series, most notably in Lassie.

Portraying Ruth Martin on Lassie

Stepping in from another actress in 1958, Lockhart remained in the show until 1964. She played Ruth Martin, married to agriculturalist Paul Martin and the foster mother of young Timmy Martin, whose dog was the titular star of the series.

Even with playing a housewife, Lockhart adeptly avoided being outshone by the brilliant dog. She characterized the program as “a fantasy about people on a farm in which the canine solves all the issues in 22 minutes, in time for the last commercial”. After she departed the show, Lockhart commented: “In six chaste years of playing a country wife and mother, I was rarely permitted to peck my on-screen husband on the cheek.”

Starring in Lost in Space

Lockhart went directly into a second hit, Lost in Space (1965-68), a semi-spoof science fiction series aimed primarily at children and based 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 show continued, the narrative became increasingly less about this space family and more about the boy and his bond with a mechanical being, and the cowardly villain Dr Zachary Smith.

Initial Career and Family Background

Lockhart’s movie first role, at the 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 performers in dozens of movies, as well as on theater, it was almost certain that June, who was born in New York, would enter show business.

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

Move to Hollywood and Film Roles

When her parent was offered 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 attending school in Beverly Hills, June began her career in films, mainly in small 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 charming as a New Yorker at a household party, whose schedule is arranged spitefully to prevent 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 sequels to the extremely successful Lassie Come Home (1943), in which another actress had played the girl who helps the canine to return to the family. In the later film, Lockhart played the now grown-up version.

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

Television and Stage Career

Although she was given major roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her movie career was getting her nowhere and that TV would be the solution. Before embarking in a new 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 further significant run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a doctor and mother figure. She also featured frequently in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy schedule 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 herself in a 1988 episode of a talkshow, where the host finds a stray collie, and in another sitcom in 1995 as the parent of a restaurant manager.

Final Career and Impact

Her final TV appearance 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 movie version featuring famous actors (1998), she had a holographic cameo as a school principal. She took pleasure 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 limited later feature films was the fantasy, Troll (1986) in which she portrayed a witch, with her own daughter, Anne Lockhart, playing her earlier self.

Personal Life and Family

In 1951 she married John Maloney, a physician 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 remembered by her daughters and four grandkids.
