Starting her career in cinema, June Lockhart, who died aged 100, found her biggest success after switching largely to television. Having been offered few chances to excel in movies from her first appearance as a youngster in 1938 until 1947, she excelled on TV in many popular series, most notably in Lassie.
Becoming Ruth Martin on Lassie
Stepping in from another actress in 1958, Lockhart continued in the series until 1964. Her role was Ruth Martin, wed to agriculturalist Paul Martin and the adoptive mother of seven-year-old Timmy Martin, whose dog was the titular hero of the series.
Even with playing a housewife, Lockhart adeptly avoided being outshone by the smart dog. She described the program as “a fantasy about families on a rural property in which the canine resolves all the issues in 22 minutes, in time for the last advertisement”. After she departed the show, Lockhart remarked: “In six sexless years of playing a rural spouse and mother, I was rarely allowed to peck my co-star on the cheek.”
Adventure into Lost in Space
Lockhart went straight into a second successful series, Lost in Space (1965-68), a partly comedic science fiction series aimed mostly at children and inspired by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two researchers investigating alien planets. Lockhart had to spend most of her time deftly trying to navigate special effects. As the show progressed, the narrative became less and less about this interstellar family and more about the young son and his bond with a mechanical being, and the cowardly villain Dr Zachary Smith.
Initial Career and Family Influence
Lockhart’s movie debut, at the 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 British-born Kathleen and Canada-native Gene were both actors in many of movies, as well as on theater, it was nearly inevitable that June, who was born in New York, would enter show business.
Her first theatrical appearance, at the tender age of six, came in a non-musical role in an opera at the Metropolitan Opera in New York (1931).
Move to Hollywood and Film Roles
When her father was offered a deal by a film studio, after his success 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 professional life in movies, mainly in minor 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 filled spitefully 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 multiple follow-ups to the extremely 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 interacted with both Lassie and her son, Laddie, protagonist of a World War II adventure in Nazi-occupied Norway, was in the minds of the creators when it came to selecting the Lassie TV series 13 years later.
TV and Stage Work
Although she was given major roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her movie career was stagnating and that television would be the answer. Before going in a different direction, she won praise 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 rural hotel, where Lockhart is a doctor and mother figure. She also featured frequently in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy workload continued for the following five decades, with a regular role in General Hospital between 1984 and 1998. Among her many guest appearances were as the actress in a 1988 episode of a comedy series, where the host finds a stray collie, and in another sitcom in 1995 as the mother of a restaurant manager.
Later Career and Impact
Her final TV credit came in 2021 as the voice of Alpha Control in an episode of a streaming service’s new version of Lost in Space. In the movie version featuring famous actors (1998), she had a holographic cameo as a school principal. She took pleasure in learning how much of an influence the first series had been to later astronauts, and often attended the organization’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 sorceress, with her own daughter, Anne Lockhart, playing her earlier self.
Personal Details
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 daughters and four grandchildren.
