Oscar Gelbfuhs (9 November 1852 in à  ternberk, Moravia â 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). Gelbfuhs invented and proposed an auxiliary scoring method for tie breaking (SonnenbornâÂÂBerger) there. A simpler version the "Neustadtl Score" later became widely used.
