June Lockhart, who died at the age of 100, started her professional journey in movies, but gained recognition after moving almost exclusively to television. Having been offered few chances to shine in movies from her first appearance as a youngster in 1938 until 1947, she excelled on television in numerous popular series, especially in Lassie.

Portraying Ruth Martin on Lassie

Stepping in from a previous star in 1958, Lockhart remained in the show until 1964. She played Ruth Martin, wed to farmer Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose collie was the titular star of the series.

In her part as a homemaker, Lockhart somehow succeeded to avoid being completely overshadowed by the intelligent canine. She characterized the show as “a fairy tale about families on a rural property in which the canine resolves all the problems in 22 minutes, in time for the last commercial”. After she left the series, Lockhart remarked: “In six chaste years of playing a rural spouse and parent, I was rarely permitted to kiss my on-screen husband on the cheek.”

Featuring in Lost in Space

Lockhart went directly into another hit, Lost in Space (1965-68), a semi-spoof sci-fi series aimed mostly at children and inspired by The Swiss Family Robinson. Lockhart and her co-star portrayed Maureen and John Robinson, two scientists investigating alien planets. Lockhart had to spend most of her time skillfully trying to navigate special effects. As the show progressed, the narrative became increasingly less about this interstellar family and increasingly about the boy and his bond with a mechanical being, and the cowardly villain Dr Zachary Smith.

Early 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 roles of her mother and father, Bob and Mrs Cratchit, were her real-life 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 inevitable that June, who was born in New York, would join show business.

Her first theatrical appearance, at the 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 given a deal by a motion picture studio, after his success on Broadway, she moved with her family to Hollywood, where Gene made approximately 300 films. After going to school in Beverly Hills, June started her professional life in films, mainly 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 delightful as a New Yorker at a family party, whose schedule is filled spitefully to prevent Lockhart interacting with her sibling.

More importantly, although she did not realize it at the time, was Son of Lassie (1945). It was one of several 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 family. In the later film, Lockhart played the now grown-up character.

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

Transition to Television and Broadway Success

Although she was offered 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 going in a new direction, she won acclaim 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 doctor and maternal character. She also appeared frequently in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy schedule continued 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 presenter finds a lost collie, and in another sitcom in 1995 as the mother of a restaurant manager.

Final Career and Legacy

Her final TV appearance came in 2021 as the voice of Alpha Control in an episode of a streaming service’s new version of Lost in Space. In the big screen version starring well-known actors (1998), she had a holographic cameo as a school principal. She took pleasure in learning how much of an influence the first series had been to future 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 subsequent feature films was the fantasy, Troll (1986) in which she portrayed a sorceress, 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 doctor. 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 grandchildren.
