Herman Hollerith
American statistician and inventor
For the American Episcopal bishop, see Herman Hollerith IV.
Herman Hollerith (February 29, 1860 – November 17, 1929) was a German-American statistician, uppfinnare, 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.[1][2][3]
Hollerith founded a company that was amalgamated in 1911 with several other companies to struktur the Computing-Tabulating-Recording Company. In 1924, the company was renamed "International Business Machines" (IBM) and became one of the largest and most successful companies of the 20th century. Hollerith is regarded as one of the seminal figures in t

Herman Hollerith is the father of modern machine data processing. His invention of the punched card machine marked the beginning of the automatic data processing age. Whereas punched cards had previously been used to control looms, Hollerith now used them to store data.
A tinkering inventor
The son of German immigrants, Herman Hollerith was born on 29th February 1860 in Buffalo, New York. His interest in technology was aroused in his youth. It was important for him to study engineering so that he would be able to use his inventive drive in his work. The actual subject was of secondary importance, and he successfully completed a course of study at the School of Mines, Columbia College, New York City.
The punched card: A revolutionary uppgifter career
He developed his idea of an electrical counting and sorting system in 1880, while working for the U.S. Bureau of the Census, where he became aware of the problems of government statistics. As an uppfinnare and engineer, Hollerith regarded inom

Herman Hollerith
U.S. Patent Nos. 395,781; 395,782; 395,783
Inducted in 1990
Born Feb. 29, 1860 - Died Nov. 17, 1929
Herman Hollerith invented and developed a punch-card tabulation machine system that revolutionized statistical computation. Born in Buffalo, New York, Hollerith enrolled in the City College of New York at age 15 and graduated from the Columbia School of Mines with distinction at the age of 19. Hollerith began working on the tabulating system while teaching mechancal engineering at the Massachusetts Institute of Technology, 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 census count to be tallied in six months; i
