The conclusion brings the book full circle and reflects on the wider historical lessons that have been learned in hidden histories of the dead, and cases of disputed bodies after WWII to the present day. It sets out the book’s main research finding that the new case material substantiates the importance of better engaging with a cultural transition in medical research from an older ethics of conviction (patriarchal medical experts, authoritarian and inward looking, prioritising their exclusive research agendas) to a new ethics of responsibility (reflecting much more medicine’s impact on society as a whole, economically, culturally and politically) for a Genome era. Six policy implications are identified from the wealth of new research material, and the conclusion reflects on how we still need to embrace a world in which DNA coding will democratise how we see and interact with a newly visible self. The substantial data employed in this volume has allowed us not only to explore existing historiographical agendas, but also to set new ones. At this research frontier, the old death sentences of the past are being delayed and we stand on the threshold of new scientific eternities that challenge our historical imaginations and patient-practitioner working relationships.
