grandmaster title

The first known use of the term grandmaster in connection with chess was in an 1838 issue of Bell's Life, in which a correspondent referred to William Lewis as "our past grandmaster". Lewis himself later referred to Philidor as a grandmaster, and the term was also applied to a few other players.
In the Ostend tournament of 1907 the term grandmaster (Großmeister in German) was used. The tournament was divided into two sections: the Championship Tournament and the Masters' Tournament. The Championship section was for players who had previously won an international tournament.[2] Siegbert Tarrasch won the Championship section, over Carl Schlechter, Dawid Janowski, Frank Marshall, Amos Burn, and Mikhail Chigorin. These players were described as grandmasters for the purposes of the tournament. ( source: Wikipedia)
