Biographies of ‘criminals’ are an immensely popular genre. As ‘true crime’ stories they are generally found on the shelves of fiction literature. In this article the authors examine their cultural criminological significance. First, they examine what makes a ‘good’ biography, analyse how biographical material is used in the work of people like Robert Park and his Chicago School, Michel Foucault and Pierre Bourdieu and indeed historians. Then the authors list different traditions of criminal biographies. They conclude by arguing that ‘good biographies’, i.e. biographies that are both sufficiently emic and offer enough context information, have a lot to offer, because they show ‘the other side’ of criminology, provide information that cannot be obtained through strictly scientific methods and counter the reductionist images prevailing in the discipline.
