Louis Adolf Grossmann

from Wikipedia, the free encyclopedia

Louis Adolf Grossmann (born September 24, 1855 in Brooklyn , † February 9, 1917 in Hamburg ) was a meteorologist .

Live and act

Grossmann was the son of a factory owner and grew up in the USA and later in Silesia . He studied mathematics, physics and astronomy in Berlin and Breslau and completed his military service in 1877/78. He then received his doctorate in 1880 in Breslau with a thesis on the calculation of the constants of the internal and external friction of gases and liquids.

After Grossmann had worked as an assistant at the Eberswalde Forest Academy from April 1880 to July 1886 , he moved to the Deutsche Seewarte in Hamburg. Here he initially worked as a laborer and assistant and received the title of professor in 1904. In 1907 he was appointed head of the department for weather telegraphy, coastal meteorology and storm warning systems . In particular, Grossmann wanted to improve the storm surge warning system, which at that time was still issuing numerous false reports. He described the relationship between storms and storm warnings on the coasts of the German Baltic and North Sea using systematic statistical methods .

Grossmann found precise mathematical formulas for basic meteorological research and entered the specialist literature with Guilbert-Grossmann's rule . The rule describes the reciprocal displacement of high pressure wedges and low troughs. The meteorologist was known to the public due to the daily autographed weather reports from the sea observatory.

Grossman died in February 1917 shortly after the end of a business prompted trip to Kurland at a pneumonia .
