Siegfried Gottwald
Siegfried Johannes Gottwald (born 30 March 1943 in Limbach, Saxony) is a German mathematician, logician and historian of science.
Life and work
From 1961 to 1966, Gottwald studied mathematics at the University of Leipzig, where he was awarded his doctor title in 1969 and his habilitation in 1977.
He is tenured professor of non-classical and mathematical logic at University of Leipzig where he taught from 1972 to his retirement in 2008. His main research areas are fuzzy sets and fuzzy methodologies, many-valued logic and history of mathematics.
He has published several books on many-valued logic, fuzzy sets and their applications, co-authored a textbook on calculus and a reader in the history of logic. He also contributed to the German biographical dictionary of mathematicians, Lexikon berühmter Mathematiker.
Professor Gottwald was Vice-Dean of the Faculty of Social Sciences and Philosophy at University of Leipzig for several years. He is married with three children.
