Starting her career in films, June Lockhart, who passed on aged 100, achieved her biggest success after shifting largely to television. Having been given limited opportunities to shine in movies from her first appearance as a youngster in 1938 until 1947, she excelled on TV in numerous beloved series, especially in Lassie.
Her Iconic Role in Lassie
Taking over from a previous star in 1958, Lockhart remained in the series until 1964. She played Ruth Martin, wed to farmer Paul Martin and the foster mother of seven-year-old Timmy Martin, whose dog was the titular star of the series.
Even with playing a mother figure, Lockhart adeptly avoided being overshadowed by the brilliant dog. She described the program as “a fairy tale about families on a farm in which the canine resolves all the problems in 22 minutes, in time for the last advertisement”. After she left the series, Lockhart remarked: “In six chaste years of playing a rural wife and mother, I was rarely allowed to kiss my co-star on the cheek.”
Adventure into Lost in Space
Lockhart went directly into another hit, Lost in Space (1965-68), a partly comedic science fiction series aimed primarily at children and inspired by The Swiss Family Robinson. Lockhart and her co-star played Maureen and John Robinson, two scientists exploring distant planets. Lockhart had to spend the majority of her time deftly trying to navigate visual effects. As the series progressed, the storyline became less and less about this space clan and increasingly about the young son and his bond with a mechanical being, and the timid villain Dr Zachary Smith.
Initial Career and Family Background
Lockhart’s movie 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 actual parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canadian-born Gene were both actors in many of movies, as well as on theater, it was almost inevitable that June, who was born in New York, would enter the entertainment industry.
Her first stage performance, at the tender age of six, came in a non-singing role in an musical production at the Metropolitan Opera in New York (1931).
Transition to Hollywood and Film Roles
When her parent was given a contract by a film studio, after his success on Broadway, she relocated with her family to Hollywood, where Gene made around 300 films. After attending school in Beverly Hills, June started 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 last one, she is charming as a New Yorker at a household party, whose dance card 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 multiple follow-ups to the extremely 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 grown-up character.
The loving way in which she handled both Lassie and her son, Laddie, protagonist of a World War II story in Nazi-occupied Norway, was in the minds of the producers when it came to selecting the Lassie TV series 13 years later.
TV and Stage Work
Although she was offered leading roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart concluded her film career was getting her nowhere and that TV would be the answer. Before going in a new direction, she received praise 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 featured regularly in TV cowboy shows in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her busy workload persisted for the following five decades, with a recurring 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 presenter finds a lost collie, and in another sitcom in 1995 as the parent of a restaurant manager.
Final Roles and Achievements
Her last TV credit came in 2021 as the voice of Alpha Control in an episode of a streaming service’s remake of Lost in Space. In the big screen version featuring famous actors (1998), she had a digital cameo as a school principal. She took pleasure in learning how much of an inspiration the original series had been to future astronauts, and often attended the organization’s launches and other events. In 2013 her work as a volunteer spokesperson brought her its prestigious award.
Among her few 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 Information
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 divorce, as did her second marriage, to John Lindsay, an designer.
She is remembered by her daughters and four grandkids.
