June Lockhart, who passed away at the remarkable age of 100, started her career in films, but gained fame after moving almost exclusively to TV. Having been offered limited opportunities to shine in movies from her debut as a child in 1938 until 1947, she thrived on television in numerous beloved series, especially in Lassie.

Becoming Ruth Martin on Lassie

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

Despite playing a mother figure, Lockhart adeptly avoided being overshadowed by the brilliant dog. She characterized the show as “a fantasy about families on a rural property in which the dog resolves all the problems in 22 minutes, in time for the last advertisement”. After she departed the series, Lockhart remarked: “In six chaste years of playing a country spouse and mother, I was rarely permitted 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 semi-spoof science fiction series aimed mostly 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 deftly trying to navigate visual effects. As the show progressed, the storyline became increasingly less about this interstellar family and more about the boy and his friendship with a robot, and the timid 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 parents, Bob and Mrs Cratchit, were her real-life parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canada-native Gene were both actors in many 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 stage performance, at the age of six, came in a non-singing role in an opera at the Metropolitan Opera in New York (1931).

Hollywood Career

When her parent was given a contract by a film studio, after his success on Broadway, she moved with her family to Hollywood, where Gene made around 300 films. After attending school in Beverly Hills, June started her career in movies, mostly 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 charming as a New Yorker at a household party, whose schedule is filled spitefully to prevent Lockhart interacting with her brother.

More importantly, 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 escape to the owners. In the later film, Lockhart played the now grown-up version.

The loving way in which she handled both Lassie and her offspring, Laddie, protagonist of a World War II story in enemy-held Norway, was in the consideration of the creators when it came to selecting the Lassie TV series 13 years later.

Shift to Television and Stage 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 solution. Before embarking in a different direction, she won praise on Broadway in For Love or Money (1947), a humorous play for which she won a Tony award as most promising newcomer.

A further significant run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a physician and mother figure. She also featured regularly in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy workload persisted for the next five decades, with a regular role in General Hospital between 1984 and 1998. Among her many guest appearances were as the actress in a 1988 episode of a comedy series, 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 last TV appearance came in 2021 as the narration of Alpha Control in an episode of a digital platform’s remake of Lost in Space. In the big screen version starring well-known actors (1998), she had a digital cameo as a school principal. She took pleasure in learning how much of an inspiration 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 representative brought her its prestigious award.

Among her limited later feature films was the fantasy, Troll (1986) in which she played 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 a second daughter, June. That union ended in separation, as did her second marriage, to John Lindsay, an designer.

She is remembered by her daughters and four grandkids.
