Karl Tobias Fischer

from Wikipedia, the free encyclopedia

Karl Tobias Fischer (born January 18, 1871 in Nuremberg , † December 31, 1953 in Munich-Solln ) was a German physicist .

Life

Karl Tobias Fischer was born in Nuremberg as the son of the master locksmith and machine manufacturer Johann Peter Fischer (1826–1873) and Christine Elise (1839–1908), daughter of the businessman and economist Andreas Herzog.

Fischer studied mathematics and physics at the University and Technical University of Munich between 1889 and 1893 . He then worked as an assistant to Walther von Dyck , Leonhard Sohncke and Hermann Ebert . In 1896, he received his doctorate from the University of Munich with the dissertation The smallest thickness of fluid membranes . A year later he completed his habilitation at the Technical University of Munich with the thesis A new barometer . In 1903 he was appointed associate professor .

In addition, Fischer became a member of the Bavarian standard calibration commission in 1907. In 1923 he was appointed head of the Bavarian State Office for Weights and Measures , which he held until 1936 and again for two years after the Second World War . Today's State Office for Weights and Measures in Munich-Nymphenburg , built between 1927 and 1930, is regarded as his work. He himself played a decisive role in the development of the precision measurement of weight, time and temperature. In 1953, Fischer was also recognized as an honorary member of the German Association for the Promotion of Mathematics and Science Education.

He was married to Valentine, the daughter of the flower manufacturer Ludwig Danzer. He was the father of the chemist Ernst Otto Fischer . Karl Tobias Fischer died a few days before he turned 83 in Munich-Solln. He is buried in the Solln cemetery.

Act

Karl Tobias Fischer's work can be divided into three sections:

The first section began with his advocacy - in the spirit of Georg Kerschensteiner - for the promotion of mathematics and science lessons. He put his experiences of trips abroad, 1898/99 England and 1904 USA , to study the teaching conditions there into influential publications .

In the second section, Fischer devoted himself increasingly to the training of physics teachers in secondary schools, with his internship and his collection of physics teaching materials having a decisive influence on two generations of teachers. Fischer continued his lectures until 1952.

The third section included Fischer's research. To this end, Fischer was engaged in experimental work in the areas of molecular physics , heat theory, electrical and magnetic measurements and low temperatures.
