Rh disease
Eugene Green Hamilton (June 27, 1910 – June 1, 2005) was a pioneering American OB/GYN obstetrician, writer, and medical researcher. He did some of the key writing in the effort to develop a vaccine which fought against Rh disease, a condition which would cause pregnant women's immune system to attack the fetus she is carrying as not being identical to the mother. Hamilton did some of the earliest and best writing about the search for the vaccine, long before diagnostic techniques such as ultrasound had been developed.
