Wilhelm Ackermann In 1928, Ackermann observed that A(x,y,z), the z-fold iterated exponentiation of x with y, is an example of a recursive function which is not primitive recursive. A(x,y,z) was simplified to a function P(x,y) of 2 variables by Rosza Peter whose initial condition was further simplified by Raphael Robinson. This last function is called Ackermann's function in today's textbooks. Also in 1928, Hilbert and Ackermann coauthored the logic book Grundzuege der Theoretischen Logik Among Ackermann's later work there are consistency proofs for set theory, full arithmetic , and type free logic. He also gave a new axiomatization of set theory in 1956, and wrote the book Solvable cases of the decision problem in 1954.

Ackermann war ein Schüler von David Hilbert in Göttingen und wurde berühmt durch die nach ihm benannte Ackermann-Funktion , ein Beispiel für eine rekursive Funktion , die jedoch nicht primitiv rekursiv ist. Von 1929 bis 1948 unterrichtete er am Gymnasium in Burgsteinfurt (Arnoldinum) und danach bis 1961 in Lüdenscheid. Er war korrespondierendes Mitglied der Akademie der Wissenschaften in Göttingen und Honorarprofessor an der Universität Münster . Gemeinsam mit David Hilbert verfasste er 1928 das Buch Grundzüge der theoretischen Logik . Außerdem wurde er durch Arbeiten zum Entscheidungsproblem der Prädikatenlogik , zur Widerspruchsfreiheit der elementaren Zahlentheorie und zur Mengenlehre bekannt.
