Roger W. Barrett, 94, a partner for many years with Mayer Brown, died earlier this year in Rancho Mirage, Calif., of complications from pneumonia.

Mr. Barrett had already started his law carer in Chicago when he joined the Army in 1943. Eventually a captain, he was enlisted for the team led by U.S. Supreme Court Justice Robert Jackson that would prosecute top Nazis in Nuremberg. He was assigned the task of assembling the government's evidence, which included everything from letters and diaries to lampshades made of human skin. He went over some of the evidence with Luftwaffe commander Hermann Goering, who he remembered as highly intelligent, arrogant and amoral. "He said that Goering was completely immoral, there was no sense of right or wrong," said his son, Oliver.
