Johann Sigismund Hubert

Johann Sigismund Hubert (1736–1792) was an Austrian hydraulic and cameral engineer who made the first attempts to shield Vienna from the Danube. In 1771 he raised a protection dam almost six metres high below the city, but floods breached it again and again.

In 1785–1786, by order of Emperor Joseph II, he built a left-bank embankment at Floridsdorf to protect the Marchfeld, later named the Hubertusdamm after him. The first large-scale regulation at Vienna followed only in the 1870s.
