I still remember some pathology lectures I heard, as a green freshman at NYU School of Medicine, in the fall of 1965 by a Venezuelan-born immunologist. They were brilliant and lucid. Baruj Benacerraf died in Boston on August 2.
A refugee in New York, he graduated Columbia in 1942. "Instead of joining the family business as his parents had hoped, he made plans to study medicine. But every medical school he applied to rejected him — because, he suspected, he was both foreign-born and a Jew."
