Elmer Belmont "Ned" Potter was an American historian and author. He was the leading naval historian at the United States Naval Academy from the late 1940s to the mid-1970s, and author/editor, in collaboration with Fleet Admiral Chester W. Nimitz, of the Naval Academy's famous textbook on naval history, Sea Power.
This was the textbook for my first naval science class in college over 30 years ago. I found a copy of it at a thrift store for 98 cents, so naturally I had to buy it. It covers the history of naval warfare from earliest times (galley warfare) through the Cold War. As a student of military history, I devoured every page back then, and it is nostalgic going through it now . It contains lots of maps and diagrams of ship formations and has very informative overviews of nearly every major naval engagement in the 200+ year time period from 1750-1980.
