This essay examines the life and work of Professor Chris Wrigley, a leading historian of British labour history, modern biography, and the modern industrial relations. It suggests that he has not only been a prolific researcher and writer but that he has also influenced a whole generation of historians, including all the contributors to this volume. In particular, it suggests that his work on industrial relations, trade unionism, and biography has been seminal in shaping current thinking. Chris Wrigley has widened our understanding of how British industrial relations have worked since the nineteenth century and examined the increasing democratisation of trade unionism. He has also examined British history through the prism of biography.
