$IBM The Historical Context of the Involvement of IBM that involves Hollerith punch cards (a company that later became IBM). During World War II, the Ñazi regime used these mechanical punch cards to manage data, cross-reference records, and track prisoners throughout the concentration camp system.
Those original punch card registries, hardfiles, and prisoner index cards were recovered by the Allies. They are not stored by IBM today; they are preserved and digitized in a massive historical database containing information on 17.5 million people.
