Baruch Samuel Blumberg, American physician and academic, Nobel Prize laureate (d. 2011)
Baruch Samuel Blumberg (July 28, 1925–April 5, 2011) — known as Barry Blumberg — was an American physician, geneticist, and co-recipient of the 1976 Nobel Prize in Physiology or Medicine (with Daniel Carleton Gajdusek), for his work on the hepatitis B virus while an investigator at the NIH. He was president of the American Philosophical Society from 2005 until his death.

Blumberg and Gajdusek received the Nobel Prize for discovering "new mechanisms for the origin and dissemination of infectious diseases." Blumberg identified the hepatitis B virus, and later developed its diagnostic test and vaccine.
