Werner Forssmann (1904-1979) was born and educated in Berlin, Germany. He developed
the first technique for cardiac catheterization, and tested the technique on himself
to prove it worked. In 1929, he put himself under local anesthetic and inserted
a catheter into his own arm. Not knowing when the catheter might pierce a vein,
he risked his own life and was able to pass the catheter into his own heart. He
shared the Nobel Prize in Medicine with Andre Cournand and Dickinson Richards in
1956 for his contribution in developing the technique of cardiac catheterization.
