Herman Hertzberger is a Dutch architect born in 1932 in Amsterdam. As a disciple of Aldo van Eyck, he was one of the main influences behind the Dutch structuralism movement. His theoretical contribution to the movement came from the Participation movement initiated in 1961 by John Habraken and his book Supports: an Alternative to Mass Housing. The theoretical ideas were translated into practical, architectural, spatial terms, such as participation, small scale, crossing disciplines, and the integrated approach to a neighbourhood. He doesn’t want to provide a complete solution, but to provide a spatial framework to be filled in by the users, it’s the Structure and Infill principle. However only his first projects will have a worldwide impact. The best known being the Diagoon Houses in Delft (1971), often considered to be the most functional structuralist housing project.
