The Sleeper Awakes - H. G. Wells

The Sleeper Awakes is a dystopian novel about a man who sleeps for two hundred years, waking up in a completely transformed London, where, because of compound interest, he has become the richest man in the world. He has been the famous Sleeper for centuries. A fanatic socialist, the main character awakes to see his nightmares realized, and the future revealed to him in all its horrors and malformities. The people adore him, and their masters - the supervisors of his legacy who rule in his name - do not want him breathing. (Summary by Stephan and Wikipedia)
