This dissertation intends to propose a theorical reflection about de discourse of biographies and its aplication by producting a biography. In order to do this, the dissertation has two parts. In the first one, we expose the theorical references that try to map the complexy of this kind of discourse construction, taking the account that we are working with multiplies and flexives nets of interpretation and discussion. In the second part, we ve made a fractal biography of Adolph Bloch, with the intention of study the multiples and complex identities of him. Our porpouse wants to escape from the ineficience of the total and unilateral explanations, and bases its references in the complexity of the interpretations.
