Theodor Krey

from Wikipedia, the free encyclopedia

Theodor Krey (born August 17, 1910 in Freiburg / Elbe ; † June 15, 1993 in Lehrte ) was a German geophysicist who mainly worked on an application basis.

resume

From 1928 to 1932 he studied mathematics , physics and geography in Göttingen and Munich (among others with Max Born and Arnold Sommerfeld ) and after a few years as a grammar school and secondary school teacher came to Seismos-GmbH , which at the time was one of two companies in Hanover carried out prospecting studies on the existence of minable oil and coal deposits underground using geophysical methods .

Such investigations were carried out in Hungary during the Second World War and in Libya and Saudi Arabia after the war. He was also involved in the preliminary geophysical investigations for the construction of the Aswan Dam in Egypt as an employee of Seismos. He has also worked several times as a geophysical expert for the United Nations in South America, including in Bolivia.

At the beginning of the fifties he became the scientific director of Seismos, and when it was taken over in 1963 by Prakla , the (state!) Competitor in Hanover, he was “bought in”.

In 1965 he received his doctorate (quasi “retrospectively”) at the Ludwig Maximilians University in Munich under Gustav Angenheister .

He received many awards and honors, including 1952 from the Society of Exploration Geophysicists of the USA (SEG) the best paper award for the work "The significance of diffraction in the investigation of faults" (The importance of diffraction in the investigation of layer faults, an application of what he had learned from Sommerfeld in a different context). In 1969 he was President of EAEG, the European Society for Applied Exploration Geophysics. In 1972 he was appointed honorary professor at the University of Hamburg . In 1988 he received an honorary doctorate from the Ruhr University in Bochum , after having become an honorary member of the Hungarian Geophysical Society two years earlier . In 1991 he was awarded the Ewing Medal by the SEG.

Seam waves

After he had made a name for himself in hard coal mining through special extensive investigations on so-called "seam waves", a certain type of such guided sound waves was named after him in 1984.

A year after his death, a colloquium was held in his honor in the Leibniz House in Hanover.
