June Lockhart: A Century of Television Stardom from Lassie to Lost in Space

Launching her career in cinema, June Lockhart, who died aged 100, found her greatest success after switching largely to the small screen. Having been given limited chances to excel in films from her first appearance as a child in 1938 until 1947, she thrived on television in many beloved series, most notably in Lassie.

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

Despite playing a housewife, Lockhart adeptly avoided being overshadowed by the brilliant animal star. She described the program as “a fantasy about families on a rural property in which the dog solves 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 rural wife and mother, I was hardly ever permitted to kiss my co-star on the cheek.”

Featuring in Lost in Space

Lockhart went directly into a second successful series, Lost in Space (1965-68), a partly comedic science fiction series targeted mostly at children and based by The Swiss Family Robinson. Lockhart and her co-star played Maureen and John Robinson, two researchers exploring alien planets. Lockhart had to spend the majority of her time skillfully trying to survive visual effects. As the show progressed, the storyline became less and less about this interstellar clan and more about the boy and his friendship with a mechanical being, and the cowardly villain Dr Zachary Smith.

Beginnings in Show Business

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 British-born Kathleen and Canada-native Gene were both actors in many of movies, 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 tender age of six, came in a non-singing role in an opera at the Metropolitan Opera in New York (1931).

Transition to Hollywood and Movie Roles

When her parent was offered a contract by a motion picture studio, after his success on Broadway, she relocated with her parents to Hollywood, where Gene made around 300 films. After attending school in Beverly Hills, June began her professional life in films, 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 delightful as a New Yorker at a household party, whose schedule is arranged spitefully to stop 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 several follow-ups to the hugely successful Lassie Come Home (1943), in which another actress had played the girl who helps the canine to escape to the family. In the later film, Lockhart played the now grown-up version.

The loving way in which she handled both Lassie and her son, Laddie, protagonist of a wartime adventure in enemy-held Norway, was in the consideration of the producers when it came to selecting the Lassie TV series 13 years later.

Shift to Television and Stage Success

Although she was given major roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her movie career was stagnating and that TV would be the solution. Before embarking 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 most promising 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 regularly in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy workload 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 host 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 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 inspiration the first series had been to later astronauts, and often participated in the organization’s launches and other events. In 2013 her work as a volunteer spokesperson brought her its prestigious award.

Among her limited subsequent feature films was the fantasy, Troll (1986) in which she played a sorceress, with her own daughter, Anne Lockhart, playing her earlier 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 union ended in separation, as did her subsequent marriage, to John Lindsay, an architect.

She is survived by her children and four grandkids.
