George Dewey. George Dewey (December 26, 1837 â January 16, 1917) was Admiral of the Navy, the only person in United States history to have attained the rank. He is best known for his victory at the Battle of Manila Bay during the SpanishâAmerican War.
As the Republican candidate for president in 1944, Dewey could not match the wartime incumbents reputation, and the nation reelected Franklin D. Roosevelt. Tenacious and unwavering, however, Dewey was nominated again in 1948, this time running against Vice President Harry S. Truman.
