June Lockhart, who died at the remarkable age of 100, started her professional journey in films, but achieved recognition after moving almost exclusively to TV. Having been offered limited chances to excel in films from her first appearance as a youngster in 1938 until 1947, she excelled on TV in many popular series, especially in Lassie.
Portraying Ruth Martin on Lassie
Taking over from another actress in 1958, Lockhart continued in the show until 1964. Her role was Ruth Martin, wed to farmer Paul Martin and the foster mother of seven-year-old Timmy Martin, whose collie was the titular star of the series.
In her role as a homemaker, Lockhart somehow succeeded to avoid being completely overshadowed by the intelligent dog. She characterized the program as “a fantasy about families on a rural property in which the dog solves all the problems in 22 minutes, in time for the last commercial”. After she departed the show, Lockhart commented: “In six sexless years of playing a country spouse and parent, I was rarely allowed to kiss my co-star on the cheek.”
Featuring in Lost in Space
Lockhart went straight into another hit, Lost in Space (1965-68), a partly comedic sci-fi series targeted primarily at children and based by The Swiss Family Robinson. Lockhart and her co-star portrayed Maureen and John Robinson, two scientists exploring alien planets. Lockhart had to spend the majority of her time deftly trying to navigate special effects. As the show progressed, the narrative became less and less about this space clan and more about the young son and his friendship with a mechanical being, and the cowardly villain Dr Zachary Smith.
Beginnings in Show Business
Lockhart’s feature film 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 actual parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canadian-born Gene were both actors in many of films, as well as on stage, it was almost inevitable that June, who was born in New York, would join show business.
Her first theatrical appearance, at the tender age of six, came in a non-singing role in an opera at the Metropolitan Opera in New York (1931).
Transition to Hollywood and Film Roles
When her father was offered a contract by a motion picture studio, after his acclaim on Broadway, she relocated with her parents to Hollywood, where Gene made approximately 300 films. After going to school in Beverly Hills, June began her professional life 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 latter, she is delightful as a New Yorker at a family party, whose schedule is filled spitefully to stop Lockhart interacting with her sibling.
More significantly, although she did not know it at the time, was Son of Lassie (1945). It was one of several sequels to the extremely successful Lassie Come Home (1943), in which another actress had played the female character who assists the canine to return to the owners. In the later film, Lockhart played the now grown-up character.
The loving way in which she interacted with both Lassie and her offspring, Laddie, hero of a wartime story in Nazi-occupied Norway, was in the consideration of the creators when it came to casting the Lassie TV series 13 years later.
Shift to Television and Broadway Achievement
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 television would be the answer. Before going in a new 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 additional substantial run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a doctor and mother figure. She also featured frequently in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic schedule continued for the next five decades, with a regular role in General Hospital between 1984 and 1998. Among her many guest appearances were as herself in a 1988 episode of a talkshow, where the presenter finds a stray collie, and in another sitcom in 1995 as the parent of a dining manager.
Later Roles and Achievements
Her last TV appearance 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 first series had been to later astronauts, and often attended the organization’s launches and other events. In 2013 her work as a unpaid spokesperson brought her its prestigious award.
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 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 union ended in separation, as did her subsequent marriage, to John Lindsay, an architect.
She is survived by her children and four grandkids.
