IBM and the Holocaust

This book, written by Edwin Black, documents the business relationship between IBM and the Nazi regime from the early days of the Third Reich to the end of World War II. Black outlines how IBM's technology, including punch cards and data processing systems, was crucial for the Nazi regime's operations, such as national census data, military logistics, and the management of concentration camps.

The book exposes the ongoing business ties between IBM and the Nazi government despite international calls for an economic boycott and the severe repression of political opponents and Jewish populations.

The expanded editions include new evidence, photographs, and internal company correspondence that further substantiate IBM's involvement.
