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

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 Ludwig-Maximilians-Universität in Munich. Bauer received his doctorate 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 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 privatdozent at Ludwig-Maximilians-Universität 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 Technical University of Munich. He retired in 1989.

Bauer's early work involved the construction of computing machinery (e.g. the logical relay computer STANISLAUS from 1951-1955). In this context, he was the first to propose the widely used stack method of expression evaluation. Bauer also worked in the committees that developed the imperative computer programming languages ALGOL 58 and its successor ALGOL 60, important predecessors to all modern imperative programming languages. In 1968, Bauer coined the term Software Engineering which has been in widespread use since.

Bauer was an influential figure in establishing computer science as an independent subject in German universities.

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 Manfred Broy, David Gries, Manfred Paul, Gerhard Seegmüller, Josef Stoer, Peter Wynn, and Christoph Zenger.

Friedrich Bauer was married to Hildegard Bauer-Vogg. He was the father of three sons and two daughters.

Definition of software engineering

Bauer was a colleague of the German Representative the NATO Science Committee. In 1967, NATO had been discussing 'The Software Crisis' and Bauer had suggested the term 'Software Engineering' as a way to conceive of both the problem and the solution.

In 1972, Bauer published the following definition of software engineering:
"Establishment and use of sound engineering principles to economically obtain software that is reliable and works on real machines efficiently."
