Siegfried Gottwald

Gottwald was born in Limbach, Saxony in 1943. From 1961 to 1966, he studied mathematics at the University of Leipzig, where he was awarded his doctor title in 1969 and his habilitation in 1977.[1]

He was a tenured professor of non-classical and mathematical logic at the University of Leipzig where he taught from 1972 to his retirement in 2008.[1] His main research areas are fuzzy sets and fuzzy methodologies, many-valued logic and the history of mathematics.[1]

He published several books on many-valued logic and on fuzzy sets and their applications, a co-authored textbook on calculus, and a reader in the history of logic. He also contributed to the German biographical dictionary of mathematicians, Lexikon berühmter Mathematiker.

Gottwald was Deputy Dean of the Faculty of Social Sciences and Philosophy at the University of Leipzig for several years. He was married with three children.
