Georg Berndt

from Wikipedia, the free encyclopedia

Georg Wilhelm Berndt (born April 22, 1880 in Grabow ; † June 2, 1972 in Dresden ) was a German measurement technician , physicist and university professor .

Life

Georg Berndt was the son of a master locksmith. He first attended elementary school and then from 1886 to 1898 the Schiller Realgymnasium in Stettin . He then studied mathematics and physics at the University of Halle . In 1901 he completed his studies with a doctorate and an examination for a higher teaching post. He completed his habilitation two years later at the University of Breslau with the writing Contributions to the knowledge of the gas spectrum as a physicist. In 1904 he became a lecturer in physics at the Friedrichs-Polytechnikum in Köthen . In 1909 he became a professor at the Physical Institute of the Instituto Nacional del Profesorado Secundario in Buenos Aires.

In 1913 he returned to Germany and initially worked in Berlin for the optical institute CP Goerz , and from 1919 for the Ludwig Loewe machine tool factory . He also taught at the TH Berlin-Charlottenburg , from 1922 as an associate. Professor. At that time he was already considered a specialist in the production and control of measuring tools and standardization.

In 1924 he was a scheduled associate. Professor for measurement technology and scientific principles of the exchange building appointed at the TH Dresden . He set up the institute for measurement technology and scientific principles of the exchange building. He headed this until his retirement in 1955, since 1946 as a full professor.

Since 1919 he was a member of the German Standards Committee. In November 1933 he signed the professors' declaration of Adolf Hitler at German universities and colleges . In 1942 he was awarded the DIN ring of honor by the German Standards Committee for his work on weight tolerances. After 1945 he was actively involved in rebuilding the partially destroyed TH Dresden. In 1953 the building of the Institute for Metrology and Scientific Basics of the Exchange Building was officially renamed Berndt-Bau. Also in 1953 he was awarded the National Prize III. Class Award, 1960 awarded the honorary title " Outstanding Scientists of the people ".

Georg Berndt died in Dresden in 1972, his grave is in the Trinitatisfriedhof there . Part of Georg Berndt's estate is now managed by the TU Dresden archive.

The “ golden rule of precision measurement technology ” goes back to Georg Berndt . It says that “the measurement uncertainty when checking a tolerance T should only be a tenth to a fifth of T”. Berndt established this rule as a rule of thumb in the 1920s and finally substantiated it scientifically in the essay Functional Tolerance and Measurement Uncertainty in 1968.
