Dutch architect Jaap Bakema (1914-1981) was a central figure within international organisations such as the the avant-gardist CIAM (Congrès Internationaux d’Architecture Moderne) originally founded in 1928, and its successor Team 10. Both organisations can be analysed in terms of networks, with a multiplicity of exchanges between the involved actors. In order to create a picture of the network and explore its connections, an interactive visualisation prototype has been developed on the basis of the correspondence present in the archive of Bakema. The prototype allows visitors to navigate between people, places and archival documents.
