Herman Hollerith designs tabulating machines for 1890 U.S. Census
The birth of modern data processing began with the U.S. Census of 1890. Tabulating machines were designed by an American inventor, Herman Hollerith. These machines reduced the time it took to count Census data by several years and saved the Census Bureau millions of dollars. The company Hollerith founded to build his electrical tabulating machines would later form the basis of the IBM corporation.
