June Lockhart, who passed away at the remarkable age of 100, began her professional journey in films, but gained recognition after transitioning almost exclusively to TV. Having been offered few opportunities to excel in movies from her debut as a youngster in 1938 until 1947, she excelled on TV in many beloved 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, wed to farmer Paul Martin and the foster mother of young Timmy Martin, whose dog was the titular hero of the series.

Even with playing a mother figure, Lockhart adeptly avoided being outshone by the brilliant animal star. She described the show as “a fairy tale about families on a farm in which the dog solves all the issues in 22 minutes, in time for the last advertisement”. After she left the series, Lockhart remarked: “In six chaste years of playing a country spouse and parent, I was hardly ever allowed to peck my co-star on the face.”

Starring in Lost in Space

Lockhart went straight into a second successful series, Lost in Space (1965-68), a partly comedic sci-fi series aimed mostly at children and based by The Swiss Family Robinson. Lockhart and another actor portrayed Maureen and John Robinson, two researchers investigating alien planets. Lockhart had to spend the majority of her time skillfully trying to survive special effects. As the show progressed, the narrative became increasingly less about this interstellar clan and increasingly about the young son and his friendship with a mechanical being, and the timid villain Dr Zachary Smith.

Beginnings in Show Business

Lockhart’s feature film 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 actual parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canada-native Gene were both performers in dozens 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 stage performance, at the tender age of six, came in a non-musical role in an musical production at the Metropolitan Opera in New York (1931).

Cinema Career

When her parent was given a deal 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 career in movies, mostly 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 latter, she is delightful as a New Yorker at a family party, whose dance card is arranged maliciously to prevent Lockhart interacting with her brother.

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 extremely successful Lassie Come Home (1943), in which another actress had played the female character who helps the dog to escape to the family. In the subsequent film, Lockhart played the now grown-up version.

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

Transition to Television and Stage Success

Although she was given major roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her film career was getting her nowhere and that TV would be the solution. Before embarking in a new direction, she won acclaim on Broadway in For Love or Money (1947), a humorous play for which she won a Tony award as best newcomer.

A additional substantial run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a physician 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 hectic 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 herself in a 1988 episode of a talkshow, where the host finds a lost collie, and in another sitcom in 1995 as the mother of a dining manager.

Later Career and Impact

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

Among her limited later feature films was the fantasy, Troll (1986) in which she played a witch, 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 medical officer. In addition to Anne, they had another daughter, June. That marriage ended in separation, as did her subsequent marriage, to John Lindsay, an architect.

She is remembered by her daughters and four grandkids.
