Ben Ferencz, the last living prosecutor from the Nuremberg trials, who tried Nazis for genocidal war crimes and was among the first outside witnesses to document the atrocities of Nazi labour and concentration camps, has died. He had turned 103 in March.

Ferencz died Friday evening in Boynton Beach, Florida.  Born in Transylvania in 1920, Ferencz immigrated with his parents to New York to escape rampant antisemitism. After graduating from Harvard Law School, Ferencz joined the U.S. Army and took part in the Normandy invasion during World War II. He then became an investigator of Nazi war crimes against US soldiers.
