Friedrich L. Bauer

Friedrich Ludwig "Fritz" Bauer (10 June 1924 – 26 March 2015) was a German pioneer of computer science and professor at the Technical University of Munich.

Life Bauer earned his Abitur in 1942 and served in the Wehrmacht during World War II, from 1943 to 1945. From 1946 to 1950, he studied mathematics and theoretical physics at the Ludwig-Maximilians-Universität München. Bauer received his Doctor of Philosophy (Ph.D.) under the supervision of Fritz Bopp for his thesis Gruppentheoretische Untersuchungen zur Theorie der Spinwellengleichungen ("Group-theoretic investigations of the theory of spin wave equations") in 1952. He completed his habilitation thesis Über quadratisch konvergente Iterationsverfahren zur Lösung von algebraischen Gleichungen und Eigenwertproblemen ("On quadratically convergent iteration methods for solving algebraic equations and eigenvalue problems") in 1954 at the Technical University of Munich. After teaching as a privatdozent at the Ludwig-Maximilians-Universität München from 1954 to 1958, he became extraordinary professor for applied mathematics at the University of Mainz. Since 1963, he worked as a professor of mathematics and (since 1972) computer science at the Technical University of Munich. He retired in 1989.

His scientific contributions spread from numerical analysis (Bauer–Fike theorem) and fundamentals of interpretation and translation of programming languages, to his later works on systematics of program development, especially program transformation methods and systems (CIP-S) and the associated wide-spectrum language system CIP-L. He also wrote a well-respected book on cryptology, Decrypted secrets, now in its fourth edition.

He was the doctoral advisor of 39 students, including Rudolf Berghammer, Manfred Broy, David Gries, Manfred Paul, Gerhard Seegmüller, Josef Stoer, Peter Wynn, and Christoph Zenger.

Friedrich Bauer was one of the 19 founding members of the German Informatics Society.
