'''Wilhelm Ackermann''' (1896–1962) was a German mathematician who made foundational contributions to mathematical logic and the theory of computability. A student of [[David Hilbert]] in Göttingen, Ackermann worked at the intersection of proof theory, set theory, and the emerging field of recursive function theory. His most enduring contribution is the [[Ackermann function]] (1928), a total computable function that is not primitive recursive, which established that the intuitive notion of computability exceeded the then-dominant formalization.

Ackermann also collaborated with Hilbert on the ''Principles of Mathematical Logic'' (1928), a text that helped establish the formalist program in the philosophy of mathematics. His work on the consistency of arithmetic and on the epsilon-calculus provided tools that would later be refined by [[Kurt Gödel]] and [[Gerhard Gentzen]]. Though less celebrated than some of his contemporaries, Ackermann's function remains a standard counterexample in computability theory, and his proof-theoretic techniques continue to influence modern logic.

The significance of Ackermann's career lies in what it reveals about the sociology of twentieth-century mathematics: a mathematician can produce a result — the Ackermann function — that is taught in every introductory computability course, while the mathematician himself remains relatively obscure. The function outlived the fame of its creator, a pattern that recurs in science and that suggests something about how knowledge propagates independently of personal reputation.
