"This is an excellent collection which brings together up-to-date scholarship on internationalism, intellectual transfers and the role of experts therein. It sheds light on the creation of transnational networks and international organizations, and on the individuals or ideas that sustained them....Driven by substantial primary research, the manuscript offers fresh insights and adds flesh to the broader conceptual discussions on 'transnational history'." · Daniel Laqua, Northumbria University "This is an excellent volume in almost every respect....It is an original contribution to the rapidly growing number of books dealing with transnational movements with a focus on social reform movements. It stretches beyond World War I and includes the period up to the 1930s, when every form of internationalism and all transnational movements were in a deep crisis. With 'experts' and 'networks' important themes of various fields of modern historiography are treated." · Martin Geyer, LMU Munich In the second half of the nineteenth century a new kind of social and cultural actor came to the fore: the expert. During this period complex processes of modernization, industrialization, urbanization, and nation-building gained pace, particularly in Western Europe and North America. These processes created new forms of specialized expertise that grew in demand and became indispensible in fields like sanitation, incarceration, urban planning, and education. Often the expertise needed stemmed from problems at a local or regional level, but many transcended nation-state borders. Experts helped shape a new transnational sphere by creating communities that crossed borders and languages, sharing knowledge and resources through those new communities, and by participating in special events such as congresses and world fairs.
