Losers in wars and political conflict tend to gravitate to the stamps and postal history of their side as a way to identify with their cause and ameliorate their sense of loss. Baltic States philately between WWI and WWII, when these countries had been absorbed by the Soviet Union, is a case in point. Confederate States philately has always enjoyed great popularity in the south as kind of rebellion by proxy – collecting those stamps gave old time Confederate collectors succor for their sense of loss of what they called their old life and their peculiar institution.
Dietz was a lifelong collector of Confederate States stamps who died in 1963. His knowledge of Confederate States philately was legendary. He lived all his life in Richmond, the capital of the Confederacy and had access to the records and archives of most of the printers for the stamps of the Confederate States. Further, in his youth he met with and interviewed many of the confederate states postal officials and had an understanding, first hand, of these stamps that would be impossible today.
