Wilhelm Engerth was born on 26 May 1814 at
Pleß in
Prussian Silesia (present-day
Pszczyna,
Silesian Voivodeship,
Poland). From 1834 Engerth studied at
Vienna - firstly architecture and then mechanical engineering - and then went to
Galicia as an architect, where he was soon entrusted with a lot of work. He returned to Vienna in order to devote himself to engineering, became a teacher of mechanics at the
Polytechnikum, then professor of descriptive geometry and, in 1844, professor of mechanics and engineering principles at the
Joanneum in
Graz. He designed a
tender locomotive for the
Semmering railway (
Semmeringbahn) which met the requirements so well that, since then, his
Engerth system has found many uses. In 1850 Engerth was nominated as the technical director (
Rat) on the executive board for railways, and later took over the Department of Engineering in the Austrian Ministry of Trade. In 1855 he took over as
Zentraldirektor of the Austrian railways and later became its managing director (
Generaldirektor). In 1859 he was a member of the
Zollenquetekommission and in 1860 he left government service. He worked with great circumspection (
Umsicht) on the organisation of technical studies in Austria and was one of the most enthusiastic proponents of regulating the
Danube river. He invented the
Schwimmtor, a barrier for preventing floating ice from entering the Danube canal. At the
Vienna World Exposition in 1873 he acted as the head of engineering and led the construction of the exhibition halls as the chief engineer. He instigated the tunnels through the
Arlberg. In 1874 he was called to the upper house (
Herrenhaus) of the Austrian parliament, the
Reichsrat and, in 1875 awarded a baronetcy. He died on 4 September 1884 in Leesdorf, part of
Baden bei Wien,
Lower Austria. His brother was the artist,
Eduard von Engerth. ==See also==
