In preparation for the many lectures I have presented to physicans, I prepared two slides based on available laboratory evidence at the FDRL and from information from Howard Bruenn's 1970 paper.
The first slide documents the abrupt rises in hemoglobin level that are absolute confirmation of at least nine transfusions FDR received in 1941. The is no other physiologic explanation. Bruenn's notion that the anemia responded to Iron therapy, like many other of his assertions, is not viable.
The second slide is a chart of FDR's weight in 1944-1945. The solid line is documented in Bruenn's paper. The dotted line is a reasonable estimate based on the countless reports of ongoing weight loss seen during three years of research.
