While the entire world knows Mark Twain as the renowned author of many classic American novels, few people are aware that he was also a highly successful businessman. In fact, more than half of his life was consumed by moneymaking pursuits, which often resulted in writing projects being neglected--but at the same time, these adventures were the inspiration behind many of the characters found in his books.

In Ignorance, Confidence, and Filthy Rich Friends, Peter Krass captures a little-known side of this American icon and details the roller coaster ride of his business ventures in a dramatic, entertaining, and informative narrative style. From Twain''s time as the founder of his own publishing house--where he made a small fortune publishing General Ulysses S. Grant''s memoirs--to his foray into venture capitalism and investment in numerous start-up firms, to his focus on his own inventions, this engaging book reveals the Mark Twain that few of us know: the no-nonsense, successful American businessman.
