Bernhard can

from Wikipedia, the free encyclopedia

Bernhard Dose (born October 3, 1884 on Nordstrand , † January 23, 1965 in Husum ) was a mechanical engineer and marine machinist who dealt with mathematics.

Live and act

Bernhard Dose was a son of the blacksmith and mechanical engineer Wilhelm Otto Dose (* 1849) from Cuxhaven and his wife Antje Christine, née Wittrock (* 1859) from Kronprinzenkoog . The father lived in Nordstrand since 1880, where he ran his own workshop and the peninsula's first steam threshing business.

Bernhard Dose first learned in his father's company, but was more interested in mathematics, which he saw as a hobby. He was considered a mathematical genius, albeit a misunderstood one by his environment. He dealt with at least nine mathematical questions, which he either solved himself or contributed to their solution. These included the Dosesche decimal fraction staircase or the approximate constructions for the side of the regular heptagon . The approximate construction appeared in the XLIV annual report of the German Mathematicians Association in 1934 and in English in the USA.

The work and studies left by Dose were taken over by the Schleswig-Holstein State Library .
