Werner Forssmann, Andre F. Cournand, and Dickinson W. Richards were aw
arded the Nobel Prize in 1956 for seminal work on heart catheterizatio
n, Forssmann for his pioneering self-experiment, and Cournand and Rich
ards for establishing heart catheterization as a standard diagnostic a
nd treatment procedure in cardiology. Forssmann's self-experiment push
ed the boundaries of medicine into a new era and opened the door of mo
dern cardiology. This historical study depicts Forssmann's life narrat
ive and the forces, political and personal as well, that shaped his pe
rsonality. His upbringing in Berlin, his career as a physician, the se
lf-experiment, and his life as a Nobel Laureate will be reviewed. His
preoccupation with euthanasia, and in the scientific community a rathe
r unknown aspect of his intellectual productivity in his late life, wi
ll also be evaluated. (C) 1997 by Excerpta Medica, Inc.
