On 11 Feb 1809, Robert Fulton patented his steamboat for the first time in the U.S., although he had already made his first successful steamboat trip on the Clermont between New York City and Albany in 1807. Others had harnessed the power of steam on land, but he applied it for propulsion of water transport of passengers. He opened up American rivers for two-way trips.
Fulton's steamboat was one of the most important inventions of his era. To learn more about what was involved in the way of financing, politics and patent litigation, read The First Steamboat.

On 11 Feb 1898, Leo Szilard was born. Today's book pick is: Genius in the Shadows : A Biography of Leo Szilard : The Man Behind the Bomb, by William Lanouette. Szilard is known as a key contributor to the Manhattan project. The author delves into the intriguing details of the ambitions, obsessions, and fears of an intensely adventurous life, and yet an enigmatic personality. The title refers to the shadows that obscured this curious physicist that have been cast by the monuments of the atomic age his work catalyzed: the Cold War, nuclear power and such icons as Robert Oppenheimer. Szilard was at the epicenter of the Manhattan Project, yet remained isolated from celebrity. This book casts light on the physicist's career and character that you may barely have known before, yet feel you must know, since his work and its consequences was so profound.
