The Second World War provided the impetus for both increased use of drugs and the emergence of an anti-doping response. By the end of the 1950s a new framework of ethics was being imposed on the drugs question that constructed doping in highly emotive terms as an ‘evil’. Alongside this emerged the science and procedural bureaucracy of testing. The years up to 1976 laid the foundations for four decades of anti-doping. This book offers a detailed and critical understanding of who was involved, what they were trying to achieve, why they set about this task and the context in which they worked. By doing so, it reconsiders the classic dichotomy of ‘good anti-doping’ up against ‘evil doping’.
