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.
John Dewey was born in Burlington, Vermont, on October 20, 1859. He was the third of four sons (the eldest had already died of injuries incurred by accident). His father, Archibald, and his mother, Lucina Rich, were both descended through long lines of Vermont farmers, though his mother's roots were considerably more socially and politically important than those of his father.
