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

Starting her career in films, June Lockhart, who passed on aged 100, found her biggest success after shifting largely to television. Having been offered limited opportunities to excel in movies from her first appearance as a youngster in 1938 until 1947, she thrived on TV in many popular series, most notably in Lassie.

Her Iconic Role in Lassie

Taking over from another actress in 1958, Lockhart remained in the series until 1964. Her role was Ruth Martin, married to farmer Paul Martin and the foster mother of seven-year-old Timmy Martin, whose dog was the titular star of the series.

Even with playing a mother figure, Lockhart adeptly avoided being overshadowed by the brilliant dog. She characterized the program as “a fantasy about families on a farm in which the dog resolves all the issues in 22 minutes, in time for the last advertisement”. After she left the series, Lockhart commented: “In six sexless years of playing a country wife and mother, I was rarely allowed to kiss my co-star on the face.”

Featuring in Lost in Space

Lockhart went straight into a second hit, Lost in Space (1965-68), a partly comedic science fiction series targeted primarily at young audiences and based by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two scientists investigating distant planets. Lockhart had to spend most of her time deftly trying to survive special effects. As the series continued, the narrative became less and less about this space clan and increasingly about the young son and his friendship with a robot, and the cowardly antagonist Dr Zachary Smith.

Start in Entertainment

Lockhart’s movie first role, at the young age of 13, had come as Belinda Cratchit in A Christmas Carol (1938). In the roles 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 dozens of movies, as well as on theater, it was almost inevitable that June, who was born in New York, would join the entertainment industry.

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).

Cinema Work

When her father was given a contract by a motion picture studio, after his acclaim on Broadway, she relocated with her family to Hollywood, where Gene made around 300 films. After attending school in Beverly Hills, June started 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 family party, whose schedule is arranged spitefully to stop Lockhart interacting with her sibling.

More significantly, although she did not realize it at the time, was Son of Lassie (1945). It was one of several sequels to the hugely successful Lassie Come Home (1943), in which another actress had played the girl who helps the dog to escape to the family. In the later film, Lockhart played the now grown-up character.

The affectionate way in which she handled both Lassie and her offspring, Laddie, protagonist of a wartime adventure in enemy-held Norway, was in the minds of the creators when it came to casting the Lassie TV series 13 years later.

Shift to Television and Stage Achievement

Although she was offered leading roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her film career was stagnating and that television would be the solution. Before going in a different 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 further significant run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a doctor and maternal character. She also appeared regularly in TV westerns 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 regular 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 mother of a dining manager.

Later Career and Legacy

Her last TV appearance 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 featuring well-known actors (1998), she had a holographic cameo as a school principal. She took pleasure in learning how much of an influence the original series had been to future astronauts, and often participated in the agency’s launches and other events. In 2013 her work as a volunteer representative brought her its Exceptional Public Achievement Medal.

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 younger self.

Personal Information

In 1951 she wed John Maloney, a doctor and former Navy doctor. In addition to Anne, they had another daughter, June. That union ended in divorce, as did her second marriage, to John Lindsay, an architect.

She is remembered by her daughters and four grandchildren.
