Friedrich Dessauer (1881-1963): the forgotten medical physicist, politician, and philosopher.

Abstract

Today, the name Friedrich Dessauer is almost forgotten; however, his scientific, social, and political works should not be. Dessauer's professional career began at a young age as a professor of physics in Frankfurt am Main. It is said that he published 400 papers and 65 book chapters and pamphlets. He was a technical inventor who established laws that dealt with theories to explain the limited understanding of the effects of radiation on cells. He advocated for methods to improve the therapeutic ratio. As a devout Catholic politician, Dessauer was an early opponent of National Socialism. This led to him being thrown into prison for political reasons in 1933. He did not leave until 1934, and then for Istanbul, largely thanks to Turkish efforts and his appointment as director of a large new institution. While he was already a well-known physicist in Germany, he had to start from scratch in order to build a modern institute. A recent article in the journal Radiotherapy and Oncology celebrated his important contributions to radiology from Turkey. After his contract in Istanbul expired in 1937, he left for the small University of Fribourg in Switzerland, where he was unfortunately unable to continue his scientific productivity. Dessauer wrote textbooks as well as political and philosophical books, and attempted to bridge the gap between Catholicism and science. Additionally, after the war, he began to teach again in Frankfurt. In photos of Dessauer, radiation-induced skin changes on his face and hands were clearly visible. Towards the end of his life, he received many medals and honors for his achievements in Germany, some of them posthumously.
