IBM, Dehomag and Technology under Nazi Rule
A historical look at punched-card technology, IBM’s German subsidiary and the ethical responsibility of technology companies.
Punched cards before modern computing
Before digital databases, punched-card systems enabled organisations to sort and tabulate large quantities of information. Such systems were used by governments, businesses and census offices around the world.
IBM and Dehomag
Dehomag, a German subsidiary associated with IBM, supplied punched-card equipment and services in Nazi Germany. Historians have examined how these technologies supported administrative record-keeping and population classification.
Evidence and historical debate
The relationship between IBM headquarters, its subsidiary and the Nazi state has been the subject of extensive historical research and debate. Claims about direct knowledge, control and particular uses of equipment should be distinguished from the well-documented existence of the business and technology.
Why this history matters
Information systems are not neutral in their consequences. They can help institutions deliver services, but they can also enable surveillance, exclusion and persecution when deployed by oppressive authorities.
Responsibility today
Modern technology companies should examine how products are used, establish safeguards and be transparent about high-risk customers and applications. The lesson is to assess the human consequences of data processing rather than celebrate technical capability alone.
