His famous Oedipal interpretation of Hamlet depended on the idea that the play was in part a response to the death of Shakespeare's father; when it turned out the father had died after the writing of Hamlet, Freud changed the history underlying his reading, not the reading itself – he bought into the theory that the play's author was an English aristocrat whose father had died in the right time frame. As a Freud biographer put it, Freud wished that "a certain part of reality could be changed."
