Information on the Pianist

I did research on the Pianist by Wladyslaw Szpillman. It was a very well known book and liked by many people. There was no research that said the author had wrote any other books besides The Pianist which was later made into a movie. I believe the reason he did not write any other books is because the only book he ever wrote was a biography. About his life during World War II and his job as Pianist. Nothing in my research showed that the book received any type of award, but I know the movie won many awards and Adrien Brody won an Oscar for his role in The Pianist. Also it was rated five out of six stars.
