Active in the late nineteenth and early twentieth centuries, Hendrik Petrus Berlage was an outstanding personality in twentieth-century Dutch architecture. His designing career consisted of extraordinary constructive achievements: the Amsterdam Stock Market, which recaptures romanesque forms by the austere simplicity of its volumes and its use of exposed brick; urbanistic plans for Amsterdam, The Hague, Rotterdam and Utrecht, based on highly unitary compositional designs in open contrast with contemporary trends; as well as extremely controversial works such as the Christian Science church and the City Museum of The Hague. The book fills in the gaps in the architect's bibliography, focusing on the less explored areas, and offers a systematic index along with a catalogue of his writings, an ample selection of archive images and a largely unpublished photographic survey.
