Bruno Taut’s unknown drawing. A history of a design for Monument des Eisens (Monument of Iron) of 1913.

Bruno Taut in his own library used to have a copy of Hendrik Peter Berlage’s well known publication Grundlagen und Entwicklung der Architektur of 1908. The book contains an original hand drawing by Taut, which allows insights into the latter’s design practise. In the picture of a geometrical proportion pattern there is Taut’s pencil drawing from 1913 of the Monument des Eisens errected for Leipziger Baufachausstellung. In the paper the author works out two aspects which are connected with Taut’s drawing. Firstly, Taut’s relation with the Dutch architect is examined. In the second step the significance of the geometrical proportion pattern for the Monuments des Eisens is analysed
