Daniel Harrwitz (29 April 1823 – 9 January 1884) was a German master (born in Breslau, Silesia) and world’s best active player in the mid 1850s. He played matches against Staunton, Anderssen, Lowenthal, and lost to Morphy. He became a professional chess player at the Cafe de la Regence in Paris. In 1852, his match with Lowenthal was the first chess match that introduced a time limit. The time limit was 20 minutes per move. In 1853-1854 he founded and edited the British Chess Review. In 1862 he wrote Lehbuch des Schachspiels. He retired in the Austrian Alps (Tyrol), living off his inheritance.
