Punch Card Tabulator
Herman Hollerith invented and developed a punch-card tabulation machine system that revolutionized statistical computation.
Hollerith began working on the tabulating system during his days at MIT, filing for the first patent in 1884. He developed a hand-fed 'press' that sensed the holes in punched cards; a wire would pass through the holes into a cup of mercury beneath the card closing the electrical circuit. This process triggered mechanical counters and sorter bins and tabulated the appropriate data.
Hollerith's system-including punch, tabulator, and sorter-allowed the official 1890 population count to be tallied in six months, and in another two years all the census data was completed and defined; the cost was $5 million below the forecasts and saved more than two years' time.
His later machines mechanized the card-feeding process, added numbers, and sorted cards, in addition to merely counting data.
In 1896 Hollerith founded the Tabulating Machine Company, forerunner of Computer Tabulating Recording Company (CTR). He served as a consulting engineer with CTR until retiring in 1921.
In 1924 CTR changed its name to . . . .
