George Davis Snell

George Davis Snell was an American immunologist born on December 19, 1903, who was awarded the Nobel Prize in Physiology or Medicine in 1980 alongside Jean Dausset and Baruj Benacerraf for their contributions to the understanding of the genetic basis of immune response. His discovery of histocompatibility antigens has been pivotal in the field of transplantation, helping to explain why some transplanted organs are accepted while others are rejected by the immune system. Snell's research has had a lasting impact on both immunology and clinical medicine.
