Scientist of the day - Baruj Benacerraf

Baruj Benacerraf was a Venezuelan-born American immunologist who was one of the co-recipients of the 1980 Nobel Prize in Physiology or Medicine. His most significant contribution is the identification of gene groups called ‘major histocompatibility complexes’ and understanding their capacity to control immune responses. Though born into a family with a business background, he was interested in pursuing science and graduated with a Bachelors degree in Science from Columbia University and a Doctor of Medicine degree from the Medical College of Virginia. He served in the US Army for a year after which he began his career as a researcher. As a researcher, he had the opportunity to work on various areas like structure of antibodies, tumor specific immunity, immunochemistry, immune complex diseases and so on. He worked in collaboration with renowned scientists like William Paul, Victor Nussenzweig, Gerald Edelman and Zoltan Ovary among many others. He was jointly awarded the 1980 Nobel Prize in Physiology or Medicine with immunologist Jean Dausset and geneticist George D. Snell.
