This archive documents what was arguably Franklin D. Roosevelt’s closest personal relationship between 1920 and 1941. While Missy’s official papers long ago moved to the FDR Library in Hyde Park, this collection constitutes the personal letters, signed books, photos and speeches she received from her boss, dating back to the 1920s. . This is the only archive of such a central figure in FDR’s life still in private hands. There will be no other opportunity to acquire such a historic archive from the Roosevelt Era.
