June Lockhart, who died at the remarkable age of 100, started her professional journey in movies, but gained fame after transitioning almost exclusively to TV. Having been given few chances to excel in movies 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

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

Even with playing a housewife, Lockhart skillfully avoided being overshadowed by the smart animal star. She characterized the show as “a fairy tale about families on a farm in which the dog solves all the issues in 22 minutes, in time for the last commercial”. After she left the series, Lockhart remarked: “In six sexless years of playing a rural wife and mother, I was hardly ever permitted to peck my on-screen husband on the face.”

Journey into Lost in Space

Lockhart went directly into a second successful series, Lost in Space (1965-68), a semi-spoof science fiction series targeted mostly at young audiences and based by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two researchers exploring distant planets. Lockhart had to spend most of her time skillfully trying to navigate special effects. As the series continued, the storyline became less and less about this space clan and more about the young son and his friendship with a mechanical being, and the cowardly antagonist Dr Zachary Smith.

Beginnings in Show Business

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 mother and father, Bob and Mrs Cratchit, were her real-life parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canadian-born Gene were both performers in many of films, as well as on stage, it was almost inevitable that June, who was born in New York, would enter show business.

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

Move to Hollywood and Movie Roles

When her parent was given a deal by a film studio, after his acclaim on Broadway, she moved with her parents to Hollywood, where Gene made approximately 300 films. After going to 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 latter, she is charming as a New Yorker at a household party, whose schedule is arranged spitefully to prevent Lockhart dancing with her brother.

More importantly, although she did not realize it at the time, was Son of Lassie (1945). It was one of several follow-ups to the extremely successful Lassie Come Home (1943), in which a young star had played the female character who helps the dog to escape to the family. In the subsequent film, Lockhart played the now adult character.

The loving way in which she interacted with both Lassie and her son, Laddie, hero of a wartime story in enemy-held Norway, was in the consideration of the creators when it came to casting the Lassie TV series 13 years later.

Transition to Television and Broadway Achievement

Although she was given leading roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her film career was stagnating and that TV would be the answer. Before embarking in a new direction, she won praise on Broadway in For Love or Money (1947), a comedy for which she won a Tony award as most promising newcomer.

A additional substantial run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a physician and mother figure. She also appeared frequently in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic workload continued for the next five decades, with a regular role in General Hospital between 1984 and 1998. Among her many guest appearances were as herself in a 1988 episode of a comedy series, where the presenter finds a stray collie, and in another sitcom in 1995 as the parent of a dining manager.

Final Roles and Contributions

Her final TV credit came in 2021 as the voice of Alpha Control in an episode of a digital platform’s remake of Lost in Space. In the movie version starring famous actors (1998), she had a holographic cameo as a school principal. She took joy in learning how much of an influence the first series had been to later astronauts, and often attended the organization’s launches and other events. In 2013 her work as a volunteer spokesperson brought her its Exceptional Public Achievement Medal.

Among her limited subsequent feature films was the fantasy, Troll (1986) in which she portrayed 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 subsequent marriage, to John Lindsay, an designer.

She is remembered by her daughters and four grandkids.
