Mozart by Paul Johnson
There are not many anecdotes about Mozart's personal life, here, although the esteemed historian, Paul Johnson does tell the story of his childhood, his autocratic father and his fight with the nasty archbishop of Salzburg, Colleredo. He also dispels the myth that Constance was not a good wife to Mozart. This is really a biography for musicians. However, Johnson adds enough to make the book more interesting, while covering Mozart's compositions and operas in a thorough and detailed way. The story of the operas, including Don Giovanni and The Magic Flute is especially enjoyable.
I also found the fact that Mozart was a Mason and that he combined this with pious Catholicism interesting. This is highly recommended for anyone who wants to read more about Mozart, although a detailed musical knowledge helps.
