'Beethoven's Hair' was truly a 'good read'. In fact, I thoroughly enjoyed reading how the lock of hair found its way to the auction, and then into the hands of the two researchers. The structure of the book is rather humorous and relates to a musical form, tossing and turning between two different time periods: Beethoven's chronological life, and the modern (including W.W.II) time of research. Indeed, the book gives you plenty of spice and reveals much about Nazism and scientology, specific to the findings in the lock of hair, but be warned... if you expect a biography of Beethoven, the one you'll get is very weak, especially in terms of his compositions. I think, though, that this would suit any reader: teachers, music-listeners, doctors, miners, and literate persons alike that can take an interest in the history of such a great genious.
