Pedro A. Loureiro is a Navy historian, curator, archivist, and USC alum who has concentrated much of his research on pre-war Japanese espionage and relations with the United States. As a graduate student majoring in Asian and Military History at San Diego State University in the 1980s, Loureiro's thesis centered on U.S. Counter-Intelligence against Japanese subversion and espionage in Southern California from 1938 to 1944.

From 1988 to 1995, Loureiro was a student at USC, where he received an M.A. and a Ph.D. His studies focused on Military History, Intelligence studies, Japanese-American History, Modern China and Modern Japan, Records Management, Oral/Video History, and Grant Writing.

During the course of his academic career, Loureiro sought materials from the United States Office of Naval Intelligence. Many of the items he received access to make up this voluminous collection, as well as additional declassified documents obtained from other government agencies, such as the National Security Agency (NSA) -- which declassified 1.3 million pages of cryptologic documents in 1996, making them available to the public -- and the U.S. Department of Justice.

Loureiro has written many journal articles on East Asian and American relations, including "Japanese Espionage and American Countermeasures in Pre-Pearl Harbor California", which was published in the Journal of American-East Asian Relations in 1994.

He was the curator of the Pacific Basin Institute at Pomona College from 1998 to 2009, an archivist at the Defense Imagery Management Operations Center from 2009 to 2016, and currently works as a historian for the U.S. Department of the Navy.

Loureiro will soon be featured on the Smithsonian Channel regarding his collection at USC as well as his academic career as a historian, scholar, and curator.
