June Lockhart: Remembering the Iconic Star of Lassie and Lost in Space

June Lockhart, who died at the age of 100, began her professional journey in movies, but gained fame after moving almost entirely to TV. Having been offered few chances to shine in films from her first appearance as a youngster in 1938 until 1947, she excelled on TV in numerous popular series, most notably in Lassie.

Her Iconic Role in Lassie

Taking over from another actress in 1958, Lockhart continued in the series until 1964. She played Ruth Martin, married to agriculturalist Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose dog was the titular hero of the series.

In her role as a housewife, Lockhart somehow succeeded to avoid being totally overshadowed by the intelligent canine. She characterized the show as “a fantasy about people on a rural property in which the dog solves all the problems in 22 minutes, in time for the last advertisement”. After she departed the show, Lockhart commented: “In six sexless years of playing a country wife and parent, I was hardly ever allowed to peck my co-star on the cheek.”

Starring in Lost in Space

Lockhart went straight into another successful series, Lost in Space (1965-68), a semi-spoof sci-fi series aimed primarily at children and inspired by The Swiss Family Robinson. Lockhart and her co-star played Maureen and John Robinson, two scientists investigating distant planets. Lockhart had to spend the majority of her time skillfully trying to survive visual effects. As the series continued, the storyline became increasingly less about this interstellar family and increasingly about the boy and his bond with a mechanical being, and the timid villain Dr Zachary Smith.

Beginnings in Show Business

Lockhart’s feature film first role, at the young 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 actual parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canada-native Gene were both actors in dozens of movies, as well as on stage, it was almost certain that June, who was born in New York, would join show business.

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

Move to Hollywood and Film Roles

When her father 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 going to school in Beverly Hills, June began her professional life in films, mostly 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 delightful as a New Yorker at a household party, whose dance card is arranged spitefully to stop 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 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 owners. In the subsequent film, Lockhart played the now grown-up character.

The loving way in which she handled both Lassie and her offspring, Laddie, hero of a World War II adventure in Nazi-occupied Norway, was in the consideration of the producers when it came to selecting 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 concluded her film career was getting her nowhere and that TV would be the answer. Before going in a new direction, she received 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 doctor and mother figure. She also appeared regularly in TV cowboy shows 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 recurring role in General Hospital between 1984 and 1998. Among her many one-off appearances were as the actress in a 1988 episode of a talkshow, where the presenter finds a stray collie, and in another sitcom in 1995 as the parent of a dining manager.

Later Roles and Contributions

Her final TV credit came in 2021 as the voice of Alpha Control in an episode of a streaming service’s remake of Lost in Space. In the movie version starring well-known actors (1998), she had a digital cameo as a school principal. She took joy in learning how much of an inspiration the original series had been to future astronauts, and often attended the organization’s launches and other events. In 2013 her work as a unpaid representative 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 Information

In 1951 she wed John Maloney, a physician and former Navy doctor. In addition to Anne, they had a second 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.
