M. Widor.  ‘While Schweitzer – for he was the pupil – explained them to me one after the other, I made the acquaintance of a Bach of whose existence I had previously had only the dimmest suspicion.  In a flash it became clear to me that the cantor of St. Thomas’s was much more than an incomparable contrapuntist to whom I had formerly looked up as one gazes up at a colossal statue, and that his work exhibits an unparalleled desire and capacity for expressing poetic ideas and for bringing word and tone into unity.’ (from Preface to the German Edition of 1908)
