Hermann Werner Siemens

from Wikipedia, the free encyclopedia

Hermann Werner Siemens (born August 20, 1891 in Charlottenburg , † December 21, 1969 in Leiden ) was a German dermatologist , twin researcher and university professor at the University of Leiden .

Life

Hermann Siemens graduated from the universities of Munich and Berlin in 1918 in Berlin with a doctorate . After brief employment with Josef Jadassohn in Breslau , he went to the dermatological clinic of the University of Munich in 1921. He was initially a private lecturer , received his habilitation in dermatology in 1923 and became an associate professor in 1927. Since 1929 he was a full professor of dermatology at the University of Leiden in the Netherlands .

With his groundbreaking study The Twin Pathology. Their significance - their methodology - their previous results from 1924, he introduced the widespread "classic twin method ". He was the first to not only use twins for a study (to determine the influence of genes in comparison to the environment on skin changes), but also to differentiate between monozygotic and dizygotic twins and to draw the correct 100% / 50% conclusions about the genetic Noted similarity in relation to these groups.

His influence on the development of twin research is widely not recognized, possibly because he supported the National Socialist "hereditary hygiene" policy . His book Fundamentals of Heredity, Racial Hygiene and Population Policy campaigned for voluntary sterility of "pathological or inferior predisposed people" and contained laudatory mentions of Hitler's ideas on racial hygiene in later editions. On the other hand, he lost his chair at the University of Leiden in 1942 and was even taken hostage for a time because of his resistance to German occupation policy. Shortly after the war, he got his faculty position in Leiden back, which he held until his retirement.

During his temporary compulsory retirement from 1942–1945 he wrote a book about his father-in-law's ancestors, which included well-known Augsburg patrician families on his mother's side: The ancestors of Friedrich von Müller , CH Beck, Munich 1957. Siemens helped Friedrich von during his time in Leiden Müller in the creation of the chapters on constitution and inheritance and basic terms of skin diseases in the paperback of medical-clinical diagnostics . Siemens was also involved in the journal for human inheritance and constitutional theory published by Günther Just and Karl Heinrich Bauer from 1935 onwards .

In 1966 he was elected a member of the Leopoldina .
