During the years following the Second World War, there were efforts in several European countries to grasp the opportunity to re-imagine "school" created through the need to rebuild on a mass scale. This article examines in detail an episode in the exchange of knowledge between English and Danish architects and educators during a period of intensive activity. Through a micro-study of documents that have survived in archives in both countries, the study tour is revealed as a key agent of exchange and as such a mapping of sites of specific interest in two countries is discussed. The origins of English-Danish exchanges are explored in the context of the rise of the modernist movement and its relationship with progressive education. A prosopographical perspective is used to understand the complexities of the social and professional relationships underpinning these exchanges. This is pursued through a detailed discussion of the meetings and site visits made during the study tours in Denmark and England during 1954. Finally, the impact of the various exchanges is assessed.
