Seduction of the Innocent is a book by German-American psychiatrist Fredric Wertham, published in 1954, that warned that comic books were a negative form of popular literature and a serious cause of juvenile delinquency. The book was taken seriously at the time, and was a minor bestseller that created alarm in parents and galvanized them to campaign for censorship. At the same time, a U.S. Congressional inquiry was launched into the comic book industry. Subsequent to the publication of Seduction of the Innocent, the Comics Code Authority was voluntarily established by publishers to self-censor their titles.
