On April 5th, 2011, Baruch Blumberg passed away. Barry was a founding member of the Association of Mars Explorers. All of us here wish to express our grief at his passing, and our gratitude for the years Barry was in our lives. Baruch Blumberg’s life story is remarkable. A scientist who seemed unbridled by convention, Barry moved easily from groundbreaking work in virology (where he won his Nobel Prize) to the young science of astrobiology. Whether serving with the US Navy during WWII or later contributing to his beef farm in Maryland, Barry’s enthusiasm for life permeated everything he touched. He will be greatly missed by all those who knew him.
