A link to a photographic image of Dr. Landsteiner

Dr. Landsteiner was an austrian immunologist and pathologist, who received the 1930 Nobel Prize for Physiology or Medicine. His primary discovery was of the major human blood groups and development of the ABO system of blood typing. His efforts ended up greatly reducing the risks of surgery and made blood transfusion a routine medical practice. Such blood type analysis proved useful also in genetic and legal applications. He also discovered the Rh factor which explained some complications of pregnancy and birth when the Rh factor of the mother and baby do not match. Dr. Landsteiner was also a ardent pipe smoker.

Put that in your pipe and smoke it!
