The third volume of Alexander Wheelock Thayer's monumental biography of Ludwig van Beethoven, edited and completed by Henry Edward Krehbiel, enters the composer's most dramatic and poignant years. It follows Beethoven from the turmoil of 1819 through the final struggles of his life, where family conflict, legal battles, illness, and creative triumph unfold side by side. The guardianship fight over his nephew Karl becomes a central domestic drama, revealing Beethoven at once fiercely devoted, wounded, controlling, and convinced that only he can shape the boy's moral future. As magistrates, tutors, and patrons intervene, the conflict deepens into a painful contest over education, inheritance, and authority. Alongside this private turmoil, the biography traces Beethoven's late masterpieces, including the Mass in D, the Ninth Symphony, and the final string quartets, as well as his dealings with publishers, admirers, and fellow musicians. Deafness makes the Conversation Books essential to his daily life, and the volume uses them to illuminate his later years with unusual intimacy. It also highlights his growing dependence on Karl Holz, whose loyalty and practical help earn Beethoven's remarkable endorsement as a future biographer. The result is a vivid portrait of genius under pressure, ending with decline, death, burial, and the lasting struggle over his legacy.
