Austrian-American logician whose 1931 incompleteness theorems are among the most significant results in the foundations of mathematics: any consistent formal axiomatic system powerful enough to describe basic arithmetic contains true statements it cannot prove, and such a system cannot prove its own consistency from within itself. The result answered, negatively, the most ambitious form of David Hilbert's program to place all mathematics on one finite, provably consistent foundation. Godel emigrated to the United States in 1940, working at the Institute for Advanced Study in Princeton alongside Einstein, and became increasingly consumed by paranoid fear of being poisoned in his final years, eventually starving himself to death after his wife, who prepared all his food, was hospitalized.

Godel proved in 1940 that the negation of CH cannot be proved from standard ZFC set theory, the first half of the independence result completed by Cohen in 1963 (Cohen has no live entity in this atlas to link to).

Why this is disputed. Godel used one specific instance of this lemma in his 1931 incompleteness paper without naming it as a separate result; Rudolf Carnap, who is not yet a live mathematician entity in this atlas, published the lemma at a general level in 1934, so crediting sole proof to Godel is disputed rather than settled.

Gödel's discoveries in the foundations of mathematics led to the proof of his completeness theorem in 1929 as part of his dissertation to earn a doctorate at the University of Vienna, and the publication of Gödel's incompleteness theorems two years later, in 1931.
