Iron Empires: Robber Barons, Railroads, and the Making of Modern America

To add some that haven't already been listed here: - The Billion Dollar Molecule: story of Vertex pharmaceuticals and their new approach to drug design - The Double Helix: story of the discovery of the structure of DNA by one of the principal scientists involved (Watson) More of a business/economic history but if you liked Titan by Chernow you would probably also like "Iron Empires: Robber Barons, Railroads, and the Making of Modern America" which is the about the history of the railroad industry in America.
