KREISEL, Georg (1923-2015)

13 offprints relating to mathematical logic and proof theory. 1949-1956.

An important collection of 13 offprints by Wittgenstein’s most respected student. Kreisel was born into a Jewish family in Graz, Austria. In 1938, just before the Anschluss, his family sent him to Britain, where he read mathematics at Trinity College, Cambridge. There he was taught by Wittgenstein, who ‘shocked Rush Rhees by declaring Kreisel to be the most able philosopher he had ever met who was also a mathematician’ (Ray Monk, Wittgenstein: The Duty of Genius, p.498). During World War II he served in the Admiralty where he met Francis Crick, and they became life-long friends. After the war, he taught at the University of Reading 1949-1954, and the majority of the offprints present here come from this period. Kreisel’s work centred on mathematical logic, stemming from Hilbert’s work on consistency in mathematics. Kreisel is probably best known for his so-called ‘unwinding’ program, whose aim was to extract constructive content from superficially non-constructive proofs. The fundamental paper outlining this program is present here in both its offprinted parts: ‘The interpretation of non-finitist proofs’ from The Journal of Symbolic Logic, 1951-2. All the offprints present in this lot are contained in a very worn envelope addressed to E. H. Neville (1889-1961) who was the mathematician who convinced Srinivasa Ramanujan to come to England. After World War I, Neville held the chair of mathematics at Reading University, and therefore was well acquainted with Kreisel.
