Der Enzyklopädist der Technischen Mechanik des 19. Jahrhunderts – Zum 200. Geburtstag von Julius Weisbach (1806–1871)

Encyclopaedist of 19th century applied mechanics – Commemorating Julius Weisbach's 200th birthday. With his two‐volume “Lehrbuch der Ingenieur‐ und Maschinen‐Mechanik” (Textbook of engineering and machine mechanics) (1845–1887), his handbook “Der Ingenieur” (The Engineer) und the journal “Der Civilingenieur” (The Civil Engineer), Julius Weisbach (1806–1871) created an image of applied mechanics reflecting the state of the industrial revolution in Germany in content and form. For the first time, he subjected the whole ‘artefact world’ of the contemporary engineer to a simple and comprehensible analysis based on applied mechanics. With his encyclopaedic publication system Weisbach succeeded in providing a valid representation of the historical/logical middle of the discipline formation period of applied mechanics (1825–1900).
