Rudolf Spielmann (1883-1942) was a Viennese professional chess player. His nickname was "The Last Knight of the King's Gambit" because he played this opening so much. In a tournament a spectator carelessly flicked an ash on Spielmann's pants, which caught on fire. He was so absorbed with the game that he failed to notice he was on fire and had to be rescued by onlookers. He was a true professional chess player who had no work outside chess. He played in over 120 tournaments and over 50 matches in his career. He released his most famous book "Richtig opfern!" (The Art of the Sacrifice) in 1935.
