Wolfgang Amadeus Mozart is considered one of the greatest geniuses in European history. In this particularly detailed biography from 1927, Otto Keller describes Mozart's extraordinary life and suffering journey. Using original documents such as excerpts from letters, poems, and newspaper articles, Keller narrates Mozart's fascinating story in a polished style. In the subsequent bibliography, he lists relevant literary and historical sources related to the life and work of the virtuoso, who continues to engage researchers to this day. I was primarily concerned with portraying Mozart as a human being, unflinchingly revealing his flaws, for only in this way could the terribly sad end of this artistic career be explained.
