How a self-taught magician and pianist became a giant of mathematical logic

In short: Raymond Smullyan was a polymath who defied conventional academic paths. A high school dropout who earned his living as a nightclub magician, he eventually became a renowned logician. His journey from composing retrograde chess puzzles to revolutionizing the understanding of Gödelian incompleteness remains one of academia's most unconventional success stories.

Born in 1919, Raymond Smullyan was a child prodigy in both music and science. After leaving high school early to pursue mathematics independently, he spent years oscillating between piano studies and logic. His early intellectual life was defined by a fascination with puzzles, particularly retrograde chess analysis, where one must deduce the history of a game from a final position. This penchant for working backward would later define his approach to formal systems.

Smullyan's academic career was as unorthodox as his interests. He lacked a formal degree for much of his early research life, earning his living by performing magic acts in Greenwich Village and teaching piano. It was only through the intervention of philosopher Rudolf Carnap that he secured a teaching post at Dartmouth College in 1954. Remarkably, the University of Chicago awarded him a B.S. in 1955 by counting a calculus course he had taught but never actually taken as a student.

His contributions to logic were profound. In 1957, he published 'Languages in which self reference is possible,' which demonstrated that Gödelian incompleteness applied to far simpler systems than previously thought. This work, completed while he was still a student, fundamentally shaped the contemporary understanding of Gödel's theorem. By the time he earned his Ph.D. from Princeton in 1959 under Alonzo Church, he had already established himself as a master of recursive set theory, eventually producing what reviewers called the most elegant exposition of the field.
