Wilhelm Krüger (civil engineer)

from Wikipedia, the free encyclopedia

Wilhelm Krüger (* 25. February 1871 in Oldenburg ; † 29. February 1940 in Wilhelmshaven ) was a German hydraulic engineering - engineering and construction director from 1933 port in Wilhelmshaven.

Life

Krüger was the son of the Oldenburg cigar dealer Friedrich Krüger (1838–1910) and his wife Catharina Sophie born. Strackerjan (1845-1910). He attended grammar school in Oldenburg and studied civil engineering at the Technical University of Hanover and the Technical University of Charlottenburg . In Hanover he became a member of the Corps Hannovera in 1891 . In 1895 he passed the first state examination to become a government building supervisor and entered the Prussian civil service for railroad training, where he became a government master builder in 1899. In 1901 he worked at the Imperial Shipyard as a civil engineer in civil engineering and hydraulic engineering. in 1907 he was promoted to building officer, in 1911 to senior building officer and in 1933 to port construction director.

In Wilhelmshaven, Krüger was particularly responsible for ensuring that the port access via the Jade Bay did not silt up and that it remained accessible to ships of the Imperial Navy with great drafts, even at low tide .

After preparatory studies in Dresden and Berlin , he set up a hydraulic engineering research institute in Wilhelmshaven in 1907, in which he was able to examine the tidal currents in the area under laboratory conditions. He supplemented these model experiments with geological-hydrographic research in the coastal area and worked closely with the Oldenburg teacher and marsh researcher Heinrich Schütte since 1907 . On the basis of this research, the jade correction was carried out under Krüger's direction between 1909 and 1931 , and with this and the construction of further correction structures at Wangerooge and Minsener Oldeoog, a new, self-regulating fairway was created. With his research, Krüger contributed to laying the foundations for scientific research on the German North Sea coast. He was also committed to the idea of ​​nature conservation and was significantly involved in securing the sea bird sanctuary on the island of Mellum .

In 1926 he was awarded an honorary doctorate from the Natural Science Faculty of the Johann Wolfgang Goethe University in Frankfurt am Main . He was one of the founders of the Working Group of North German Geologists. He retired on June 1, 1936 and died four years later of pneumonia.

Streets in Oldenburg and Wilhelmshaven are named after him. The Wilhelm Krüger hopper excavator, which was commissioned in 1942, is still in use in the Kiel Canal today .

family

Krüger was married to Anna Piesbergen (1879–1951) since 1901.
