Pedro Loureiro papersPedro Loureiro is an historian who has concentrated much of his research on pre-War Japanese espionage and relations with the United States. In the course of his research, he applied for and gathered a sizable collection (24,000+ pages) of declassified documents from such agencies as the Asiatic Fleet, the 4th Marine Regiment (the "China Marines"), American Naval Attaches in Peiping (Beijing) and Tokyo and the Federal Bureau of Investigation. The collection documents many details of the political, economic, military and social conditions in East Asia during the 1920s and 1930s.
