The First Submarines: The Beginnings of Underwater Warfare

Richard Compton-Hall

It includes many wonderful inventions and even more colourful inventors, but focuses primarily on John Philip Holland, the Irish-American genius who took submarine development out of the hands of lunatics and visionaries and turned it into a deadly weapon of war
