Who was Alfred Thayer Mahan?
Alfred Thayer Mahan was a United States naval officer, who became famous as an eminent naval historian and strategist. Born to a noted military theorist, he entered US Naval Academy against his father’s wishes. Although he saw action during the American Civil War and actively served the US Navy for 40 years, his skill as a seaman was not particularly exemplary. Indeed, most ships under his command were involved in collisions. Contrarily, he was a great strategist and author, publishing his first book, ‘The Gulf and Inland Waters’ around the age of 43. Two years later, he was invited to join the newly founded Naval War College as a professor, publishing his college lectures as ‘The Influence of Sea Power upon History, 1660–1783’ at fifty. Six years later, he voluntarily retired to concentrate on writing. Today, he is known as one of the most influential American authors of the 19th century.
