Norman Bates was published by Robert Bloch.
Bloch sums up Norman's multiple personalities in his stylistic form of puns: "Norman", a child needing his mother; "Norma", a controlling, mean-spirited parent figure; and "Normal", a functional adult who goes through the motions of day-to-day life
 Bates (Olivia Hussey) suffered from schizophrenia and borderline personality disorder and passed the illnesses on to her son
