Herman Hollerith was a German-American statistician, inventor, and businessman who developed an electromechanical tabulating machine for punched cards to assist in summarizing information and, later, in accounting. His invention of the punched card tabulating machine, patented in 1884, marks the beginning of the era of mechanized binary code and semiautomatic data processing systems, and his concept dominated that landscape for nearly a century.
Replica of Hollerith tabulating machine with sorting box, circa 1890. The "sorting box" was an adjunct to, and controlled by, the tabulator. The "sorter", an independent machine, was a later development.
