Passages:
Rear Admiral Patricio Montojo y Pasarón (September 7, 1839 – September 30, 1917) was a career Spanish naval officer who commanded the restored Kingdom of Spain's Pacific Squadron based in the Philippines during the Spanish–American War.  Considered to have been a man of high ability and experience, he was given what was regarded as an impossible task of defending the Spanish Philippines with antiquated ships and low supplies against the more formidable U.S. Asiatic Squadron.  Montojo became known for his defeat at the Battle of Manila Bay (1 May 1898) by U.S. Navy Admiral George Dewey, being a decisive naval battle of the war.  After the conflict, the rear admiral was held accountable for the defeat and was court-martialed, but that was later overturned, though Montojo was still discharged from the Spanish Navy. Luke McNamee (April 4, 1871 – December 30, 1952) was a United States Navy Admiral, businessman, and the 10th and 12th Naval Governor of Guam.  He served in the Navy for 42 years, during which time he held multiple commands.  During the Spanish–American War, he earned the Navy Cross, and later the Legion of Honour.  Earlier on his career, he served as governor, and expanded funding for fighting the infectious diseases running through the native population.  He represented the U.S. Navy as a delegate to the Paris Peace Conference in 1919.  He later became Director of the Office of Naval Intelligence.  He was promoted to full admiral after being placed in charge of the Battle Fleet.  After this command, he served as President of the Naval War College before retiring in 1934.  After leaving the Navy, he became President and Chairman of the Mackay Radio and Telegraph Company, where he aggressively expanded telegraph and radio service overseas. Hispanic Admirals in the United States Navy can trace their tradition of naval military service to the Hispanic sailors, who have served in the Navy during every war and conflict since the American Revolution.  Prior to the Civil War, the highest rank reached by a Hispanic-American in the U.S. Navy was Commodore.  Such was the case of Commodore Uriah Phillips Levy (1792–1862), a Sephardic Jew of Hispanic descent and great grandson of Dr. Samuel Nunez, who served in the War of 1812.  During the American Civil War, the government of the United States recognized that the rapid expanding Navy was in need of admirals therefore, Congress proceeded to authorize the appointment of nine officers the rank of rear admiral.  On July 16, 1862, Flag Officer David Glasgow Farragut became the first Hispanic-American to be appointed to the rank of rear admiral.  Two years later (1864), Farragut became a vice admiral, and in 1866 the Navy's first full admiral.  During World War I, Robert Lopez, the first Hispanic graduate of the United States Naval Academy, served with the rank of commodore in command of the Mare Island Naval Shipyard, and during World War II five Hispanics served with the ranks of rear admiral or above in either the European or Pacific Theater's of the war.  As of April 2007, twenty-two Hispanic-Americans have reached the rank of admiral, and of this number thirteen were graduates of the USNA. David Chanoff is a noted author of non-fiction work.
