Ludwig van Beethoven (1770-1827) is recognized the world over as a composer of musical masterpieces exhibiting heroic strength, particularly in the face of his increasing deafness from ca. 1798. By 1818, the Viennese composer had begun carrying blank booklets with him, for his acquaintances to jot their sides of conversations, while he answered aloud. Often, he himself used the pocket-sized booklets to make shopping lists and other reminders, including occasional early sketches for his compositions. Today, 139 of these booklets survive, covering the years 1818 up to the composer's death in 1827 and including such topics as music, history, politics, art, literature, theatre, religion, and education as perceived on a day-to-day basis in post-Napoleonic Europe. An East German edition, begun in the 1960s and essentially complete by 2001, represents a diplomatic transcription of these documents. It is a masterpiece of pure scholarship but is difficult to use for anyone who is not a specialist. Moreover, Beethoven scholarship has moved on significantly since the long-ranging genesis of the German edition. --Theodore Albrecht is Professor of Musicology at Kent State University, Ohio.
