German chess master; born 1823 in Breslau, Silesia; died Jan. 9, 1884, at Botzen, Tyrol; received most of his chess-training from Anderssen. Harrwitz lived for some time in France, and at intervals in England. His chess career may be said to have begun in Paris in 1845. In the following year he lost a match with Staunton at the odds of a pawn and two moves, but won another at pawn at move. He then defeated Horwitz and Löwenthal in England and De Rivière in Paris. In 1858 he lost a match with Morphy by 2 games to 5; but before the match he won an additional game, thus gaining the rare distinction of winning three games from that distinguished player. In 1862, owing to ill health, Harrwitz was compelled to relinquish active participation in the game. As a giver of odds, he was perhaps the most successful of all chess-players.
In 1853-54 Harrwitz published "The British Chess Review." He was also the author of "Lehrbuch des Schachspiels," Berlin, 1862.
