Benoit is best known for playing Nancy Remington, the sweetheart and eventual wife of Wally Cox's character on the 1950s NBC sitcom Mister Peepers. The show, broadcast live from a New York theater for three seasons from July 1952 to June 1955, starred Cox (later the voice of the superhero Underdog) as the mild-mannered Robinson Peepers, a science teacher at Jefferson City Junior High. Benoit's Nancy was a nurse and the object of Peepers' awkward affection.
In a highly anticipated television moment, the two were married near the end of the second season, with the new husband and wife on the cover of TV Guide in May 1954.
Born on February 21, 1927, in Fort Worth, Texas, Benoit attended Texas State College before moving to New York City when she was 19.
She studied acting at the American Academy of Dramatic Arts, appeared on a 1950 episode of Believe It or Not and had a career breakthrough when she starred as Melvyn Douglas' long-lost daughter in the 1951-1952 Broadway comedy Glad Tidings.
