Ira Levin decided on a career of a writer at the age of 15. Educated at the elite Horace Mann school, he went on to two years at Drake University in Des Moines, Iowa, before transferring to New York University, where he majored in philosophy and English. He earned his degree in 1950. In 1953 he was drafted into the army. Based in Queens, New York, he wrote and produced training films for Uncle Sam before moving into television, penning scripts for such anthology series as Lights Out (1946) and The United States Steel Hour (1953). He made a bright theatre debut at the age of 25 with an adaptation of Mac Hyman's "No Time for Sergeants" (1955). He went on to write several plays, including the longest-running Broadway mystery to date, "Deathtrap" (1978), and several popular novels.
