The authority for Haydn's life is the biography begun by the late Dr Pohl, and completed after his death by E.V. Mandyczewski. To this work, as yet untranslated, every subsequent writer is necessarily indebted, and the present volume, which I may fairly claim to be the fullest life of Haydn that has so far appeared in English, is largely based upon Pohl. I am also under obligations to Miss Pauline D. Townsend, the author of the monograph in the "Great Musicians" series. For the rest, I trust I have acquainted myself with all the more important references made to Haydn in contemporary records and in the writings of those who knew him. Finally, I have endeavoured to tell the story of his career simply and directly, to give a clear picture of the man, and to discuss the composer without trenching on the ground of the formalist.
