Winfield W. Riefler (1897–1974) was an American economist and statistician who helped create the Federal Housing Administration and was instrumental in the 1951 Treasury-Fed Accord Riefler is credited with inventing the modern amortized home mortgage. This new mortgage type was designed to be more stable than the balloon mortgages common during the 1920s, which had led to the National Mortgage Crisis of the 1930s. His Riefler-Burgess framework stood in opposition to the real bills doctrine as a guiding philosophy of U.S. monetary policy in the early 1930s.
