Gerda Henkel Visiting Professorship Lecture. Coffee, one of the most important global commodities since the late 19th century, has connected very different physical, social and symbolic worlds. The project Dorothee Wierling will present and discuss in her talk, focuses on one group of actors, those engaged in the overseas trade of the unfinished product: the coffee merchants as agents of globalisation. The talk will explore the economic, social and political frameworks in which those merchants acted and, in doing so, hopes to come up not only with a case study on the interaction of the global and the local, but also with the social and cultural history of an elite, which went through significant changes during the "age of extremes". The lecture was given on 22 October 2013 at the German Historical Institute London.
