<b>1893 > Bruxelles</b> ° 1.4.1862; + 22.10.1922. Professor of descriptive geometry at the "Université libre de Bruxelles". His friend Victor Horta built him a townhouse at Rue de Turin, 6 (present-day Rue Paul Emile Janson) in 1893, designed on Art Nouveau principles. The building is a landmark in the development of domestic architecture, revolutionary in its use of space, industrial building materials and decoration. It was also constructed to take Tassel's passion for photography (and later cinematography) into account: a darkroom on the entre-sol gave onto an area with a balcony, enabling Tassel to project images onto a screen unfurled below in the ground-floor hallway.
