A. T. Mahan

Alfred Thayer Mahan was a United States Navy (USN) officer and historian whom John Keegan called "the most important American strategist of the nineteenth century." His 1890 book The Influence of Sea Power upon History, 1660–1783 won immediate recognition, especially in Europe, and with the publication of its 1892 successor, The Influence of Sea Power upon the French Revolution and Empire, 1793–1812, he affirmed his status as a globally-known and regarded military strategist, historian, and theorist. Mahan's works encouraged the development of large capital ships—eventually leading to dreadnought battleships—as he was an advocate of the 'decisive battle' and of naval blockades.
