In 1798 Franz Xaver Niemetschek published this biography of Mozart - the only one written by an eyewitness and authorized by Mozart's widow Konstanze. It includes a dedication to Haydn and is one of the earliest specimens of musical biography which, compared with other branches of biography, was still in its infancy even in the latter part of the 19th century. This first biography of Mozart is not only an important document of music history but also a loving and intimate portrait of the world-renowned composer. Based on documents, letters and other original sources, Mozart: The First Biography conveys a vivid picture of the social and courtly life that formed the background of Mozart's sheer magical talents as a composer and virtuoso.
