The Great German Composers

The Great German Composers is a classic music book and a great collection of biographies of great German composers that contains this snippet:
The sketches of composers contained in this volume may seem arbitrary in the space allotted to them. The special attention given to certain names has been prompted as much by their association with great art-epochs as by the consideration of their absolute rank as composers.
The introduction of Chopin, born a Pole, and for a large part of his life a resident of France, among the German composers, may require an explanatory word. Chopin's whole early training was in the German school, and he may be looked on as one of the founders of the latest school of pianoforte composition, whose highest development is in contemporary Germany. He represents German music by his affinities and his influences in art, and bears too close a relation to important changes in musical form to be omitted from this series.
