Belle Mayer of New York was a prosecutor on the team that tried I.G. Farben, one of Nazi Germany’s largest government contractors, which had a large stake in creating the Zyklon-B poison used in death-camp gas chambers.

During a well-known case involving German industrialists who reaped enormous profits providing armaments to the Nazi regime with the help of slave labor at concentration camps, the defendants faced Cecelia Goetz -- the only woman ever to deliver an opening statement at the Nuremberg Trials.

As a lawyer at the Nuremberg Trials, Harriet Zetterberg made breakthrough discoveries. But as the only woman on the prosecutorial staff, she had to look on as male members of the team presented her work.

During the trials, she worked as a research analyst. Her command of the English and German languages made her an invaluable resource to the prosecution.
