Oscar Gelbfuhs
From Wikipedia, the free encyclopedia
Oscar Gelbfuhs (9 November 1852 in Šternberk, Moravia – 27 September 1877 in Cieszyn, Austrian Silesia) was a chess master from Austria-Hungary.
He took 11th in the Vienna 1873 chess tournament (Wilhelm Steinitz and Joseph Henry Blackburne won).[1] Gelbfuhs invented and proposed an auxiliary scoring method for tie breaking (Sonnenborn–Berger) there.[2] A simpler version the "Neustadtl Score" later became widely used.[3]
