Starting her career in films, June Lockhart, who died aged 100, found her biggest success after switching predominantly to the small screen. Having been offered few opportunities to excel in films from her first appearance as a youngster in 1938 until 1947, she thrived on TV in numerous popular series, most notably in Lassie.
Her Iconic Role in Lassie
Taking over from a previous star in 1958, Lockhart remained in the show until 1964. Her role was Ruth Martin, married to farmer Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose dog was the eponymous hero of the series.
In her role as a homemaker, Lockhart somehow managed to avoid being totally upstaged by the clever dog. She described the show as “a fantasy about families on a rural property in which the dog solves all the issues in 22 minutes, in time for the last advertisement”. After she departed the series, Lockhart remarked: “In six chaste years of playing a country spouse and mother, I was hardly ever allowed to peck my on-screen husband on the face.”
Journey into Lost in Space
Lockhart went directly into a second successful series, Lost in Space (1965-68), a partly comedic sci-fi series targeted mostly at children and based by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two researchers exploring distant planets. Lockhart had to spend most of her time deftly trying to navigate visual effects. As the show continued, the narrative became less and less about this interstellar family and increasingly about the boy and his bond with a mechanical being, and the cowardly villain Dr Zachary Smith.
Beginnings in Entertainment
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 mother and father, Bob and Mrs Cratchit, were her actual parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canada-native Gene were both performers in dozens of films, as well as on theater, it was nearly certain that June, who was born in New York, would enter the entertainment industry.
Her first stage appearance, at the age of six, came in a non-singing role in an opera at the Metropolitan Opera in New York (1931).
Cinema Work
When her parent was given a deal by a motion picture studio, after his acclaim on Broadway, she moved with her family to Hollywood, where Gene made approximately 300 films. After going to school in Beverly Hills, June began her career in films, mainly 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 last one, she is delightful as a New Yorker at a household party, whose schedule is filled maliciously to prevent 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 sequels to the hugely successful Lassie Come Home (1943), in which another actress had played the female character who assists the dog to return to the family. In the subsequent film, Lockhart played the now adult character.
The affectionate way in which she handled 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 casting the Lassie TV series 13 years later.
Television and Theater Career
Although she was given leading roles in two suspense films, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her film career was stagnating and that TV would be the answer. Before embarking in a new direction, she received acclaim 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 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 workload persisted 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 comedy series, where the host finds a lost collie, and in another sitcom in 1995 as the parent of a dining manager.
Later Career and Legacy
Her last TV credit came in 2021 as the narration of Alpha Control in an episode of a streaming service’s remake of Lost in Space. In the movie version starring famous actors (1998), she had a holographic cameo as a school principal. She took joy in learning how much of an influence the original series had been to later astronauts, and often participated in 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 played a witch, 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 a second daughter, June. That marriage ended in separation, as did her second marriage, to John Lindsay, an designer.
She is survived by her children and four grandchildren.
