Dmitri Shostakovich. He's my absolute hero. Aside from being an incredibly gifted composer and pianist, he was a great example of the struggle against censorship in the Soviet era. You can hear all sorts of political hints in his music, as well as a great sense of wit. Because his music was denounced by the Soviet government twice (and a lot of it was even banned), he appeared to submit to them by composing to their standards and wishes, but all the while adding subtle sarcasms and criticisms that they wouldn't detect. It's amazing how he used his medium to pretty much give Stalinism the middle finger, and not get caught. He lived a terrifying life at times, though. Friends and relatives of his would simply disappear due to the Stalinist regime.
He was also a fireman in World War 2, a qualified football referee, and a rather heavy vodka drinker.
