Alonso Fernández de Avellaneda

Alonso Fernández de Avellaneda is the pseudonym of a man who wrote a sequel to Cervantes' Don Quixote. The identity of Avellaneda has been the subject of many theories, but there is no consensus on who he was. It is not clear that Cervantes knew who Avellaneda was although he knew that it was a pseudonym and that the volume's publication information was false. One theory holds that Avellaneda's work was a collaboration by friends of Lope de Vega. Another theory is that it was by Gerónimo de Passamonte, the real-life inspiration for the character Ginés de Pasamonte of Part I.
