Erich Hecke

Erich Hecke was a German mathematician known for his work in number theory and the theory of modular forms.

Biography

Hecke was born in Buk, [Greater Poland Voivodeship|Buk], Province of Posen, German Empire. He obtained his doctorate in Göttingen under the supervision of David Hilbert.
Kurt Reidemeister and Heinrich Behnke were among his students.
In 1933 Hecke signed the Vow of allegiance of the [Professors of the German Universities and High-Schools to Adolf Hitler and the National Socialistic State|Loyalty Oath of German Professors to Adolf Hitler and the National Socialist State], but was later known as being opposed to the Nazis.
Hecke died in Copenhagen, Denmark.
André Weil, in the foreword to his text Basic Number Theory says: "To improve upon Hecke, in a treatment along classical lines of the theory of algebraic numbers, would be a futile and impossible task", referring to Hecke's book Lectures on the Theory of Algebraic Numbers.

Research

His early work included establishing the functional equation for the Dedekind zeta function, with a proof based on theta functions. The method extended to the L-functions associated to a class of characters now known as Hecke characters or idele class characters; such L-functions are now known as Hecke L-functions. He devoted most of his research to the theory of modular forms, creating the general theory of cusp forms, as it is now understood in the classical setting.

Recognition

He was a Plenary Speaker of the ICM in 1936 in Oslo.
