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

June Lockhart, who died at the age of 100, started her professional journey in movies, but achieved fame after transitioning almost entirely to TV. Having been offered few chances to excel in films from her first appearance as a child in 1938 until 1947, she thrived on TV in numerous beloved series, especially in Lassie.

Her Iconic Role in Lassie

Taking over from a previous star in 1958, Lockhart continued in the series until 1964. Her role was Ruth Martin, married to agriculturalist Paul Martin and the adoptive mother of young Timmy Martin, whose collie was the eponymous hero of the series.

Even with playing a mother figure, Lockhart adeptly avoided being overshadowed by the brilliant animal star. She described the show as “a fairy tale about people on a farm in which the dog resolves all the problems in 22 minutes, in time for the last commercial”. After she left the series, Lockhart remarked: “In six sexless years of playing a country wife and mother, I was rarely permitted to peck my co-star on the face.”

Adventure into Lost in Space

Lockhart went straight into another successful series, Lost in Space (1965-68), a semi-spoof science fiction series aimed mostly at young audiences and inspired by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two scientists exploring alien planets. Lockhart had to spend the majority of her time skillfully trying to navigate special effects. As the series continued, the narrative became increasingly less about this space family and increasingly about the young son and his friendship with a robot, 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 roles of her mother and father, Bob and Mrs Cratchit, were her real-life parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canadian-born Gene were both performers in many of films, as well as on theater, it was almost certain that June, who was born in New York, would join show business.

Her first stage appearance, 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 Work

When her father was given a deal by a film studio, after his acclaim on Broadway, she moved 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 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 family party, whose dance card is filled spitefully to prevent Lockhart interacting with her sibling.

More importantly, although she did not know it at the time, was Son of Lassie (1945). It was one of multiple sequels 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 affectionate way in which she interacted with both Lassie and her son, Laddie, protagonist of a World War II adventure in enemy-held Norway, was in the consideration of the creators when it came to casting the Lassie TV series 13 years later.

Transition to Television and Stage Success

Although she was offered leading roles in two thrillers, 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 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 best newcomer.

A additional significant run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a doctor and mother figure. She also appeared regularly in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic schedule persisted for the following five decades, with a recurring role in General Hospital between 1984 and 1998. Among her many guest appearances were as herself in a 1988 episode of a comedy series, where the presenter finds a stray collie, and in another sitcom in 1995 as the parent of a restaurant manager.

Final Roles and Contributions

Her last TV credit came in 2021 as the voice of Alpha Control in an episode of a digital platform’s new version of Lost in Space. In the big screen version featuring 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 participated in the agency’s launches and other events. In 2013 her work as a unpaid spokesperson brought her its prestigious award.

Among her few subsequent feature films was the fantasy, Troll (1986) in which she played a witch, with her own daughter, Anne Lockhart, playing her earlier self.

Personal Life and Family

In 1951 she married John Maloney, a physician and former Navy medical officer. In addition to Anne, they had a second daughter, June. That marriage ended in divorce, as did her second marriage, to John Lindsay, an designer.

She is remembered by her children and four grandchildren.
