Illustrated with a frontispiece photograph of Herbrand. Edited by Warren D. Goldfarb. A translation of Ecrits Logiques, edited by Jean Van Heijenoort. Dauben 1606. Omega Bibliography, volume III, 351. Herbrand is best known for two important results, the Herbrand theorem in classical logic and (one direction of) the Herbrand-Ribet theorem in class field theory. Herbrand's proof of the former result is included in this book (V. Investigations in Proof Theory (1930)) and is a well-known and significant theorem in mathematical logic (Herbrand shows that certain formulas in first-order logic are reducible to formulas in propositional logic in the sense a first-order formula of the right sort is valid just in case the propositional "translation" formula is valid).
