Alfred Thayer Mahan
He was born in West Point, New York on December 27, 1840. His dad, Dennis Hart Mahan, was a professor at the United States Military Academy. His mom was Mary Helena Mahan. He first attended St. James School in western Maryland, but then transferred to the Naval Academy, where he graduated second in his class. In 1861 he fought in the Civil War for the Union. He was an officer on the USS Worcester, Congress, Pocahontas, and James Adger. After the Civil War, he was commander of USS Wachusett, and was stationed in Peru to protect american interests in the War of the Pacific. He was appointed lecturer at the Naval War College where he met Theodore Roosevelt, the future president. While he was at the College he developed ideas about the Navy. He helped established the U.S. Navy's Great White Fleet. He died on December 1, 1914, from heart failure.
His ideas has enormous impact on navies around the world. He has been called the most important american strategist of the 19th century. The Ideas Mahan had are still apart of the U.S. Navy Doctrine today.
I think Mahan changed the U.S. Navy because of all of his ideas. If the ideas are still around today, they must've been good ideas. I think he showed the world of the U.S. naval power because he presented the Great White Fleet to the world by sailing them around the world.
