Information About

Dehomag




Under Nazi Germany , Dehomag was the company that leased and maintained the Nazis' collection of punch card machines. The use of this technology increased the efficiency of the Final Solution greatly.

The Hollerith Punch-card system was invented for the U.S. Census Bureau around 1890 by German-American Herman Hollerith. He leased the machines to foreign governments as well for census work, including Russia. Willy Heidinger, an acquaintance of Hollerith's and soon-Nazi supporter, licensed all of Hollerith’s patents in 1910, and created DEHOMAG, leasing Hollerith technology in Germany.
