“My researches had for their object the whole life of Chopin, and his historical, political, artistical, social, and personal surroundings, but they were chiefly directed to the least known and most interesting period of his career—his life in France, and his visits to Germany and Great Britain. My chief sources of information are divisible into two classes—newspapers, magazines, pamphlets, correspondences, and books; and conversations I held with, and letters I received from, Chopin's pupils, friends, and acquaintances."
