Ferdinand Dannmeyer

from Wikipedia, the free encyclopedia

Ferdinand Dannmeyer (born August 26, 1880 in Kiel , † November 13, 1959 in Hamburg-Groß Borstel ) was a German meteorologist.

Life

Ferdinand Dannmeyer studied under Paul Stäckel in Kiel and wrote his dissertation in 1904, The Surface and Volume Calculation for Lobatschefskij 's Space, with special consideration of the rotational solids and polyhedra .

During the First World War he was an artilleryman in Flanders .

Then he founded the Institute for Physical-Biological Light Research e. V. to research the effects of light on people, especially the still little-known UV light . There, the physicist developed Franz Skaupy (1882-1969) of the Auergesellschaft the first Vitalux lamp, an incandescent lamp with UV-transmitting glass bulb as a mild Dorno emitters (UV-B).

From 1920 to 1922 he examined the visibility conditions at sea. He was able to follow the haze of the big cities for 100 km to the leeward.

At his suggestion, his colleague Joachim Schubert examined the UV intensity of the sun in Africa and discovered ozone holes .

He supported Hans Ulrich Roll in his long-term research on the formation of ocean waves through the action of wind and made the institute building on Neuwerk available.

In 1926 he made his first trip to Iceland . He made acoustic depth measurements up to a depth of 1500 m. In Iceland he also discovered that the UV radiation of the arctic sky is many times stronger than in his home country - even after sunset ( Dannmeyer phenomenon ). He identified the haze of the Gulf Stream as the cause. When measuring the wind speed at great heights, he discovered the jet stream at a height of 8-14 km .

His daughter Lieselotte married the documentary filmmaker Alfred Ehrhardt around 1938 .

In 1950 he founded the Society of Friends of Iceland in Hamburg and was awarded the Great Knights Cross of the Order of the Falcons by the Icelandic President in 1954 .
