Herman Hollerith (Buffalo, New York, February 29, 1860 – Washington, D.C., November 17, 1929) was a German-American statistician who developed a mechanical tabulator based on punched cards in order to rapidly tabulate statistics from millions of pieces of data.

Hollerith entered the City College of New York in 1875 and graduated from the Columbia University School of Mines with an "Engineer of Mines" degree in 1879.

Columbia University is a private University in the United States and a member of the Ivy League. In 1890, on September 15, he married Lucia Beverley Talcott (December 3, 1865 – August 4, 1944) of Veracruz, Mexico, and they had six children (three sons and three daughters).

Veracruz, formally Veracruz de Ignacio de la Llave is one of the 31 states that constitute the republic of Mexico. The United Mexican States ( or commonly Mexico (ˈmɛksɪkoʊ () is a federal constitutional Republic in North America.  Other than his inventions, Hollerith "was said to cherish three things: his German heritage, his privacy and his cat Bismarck. " He also "liked good cigars, fine wine, Guernsey cows, and money. . . . He disliked property taxes and hard-driving salesmen. "
At the urging of John Shaw Billings, Hollerith developed a mechanism to make electrical connections trigger a counter to record information. Oak Hill Cemetery is a twenty-two Acre (9 ha) historic Cemetery and Botanical garden located in Georgetown Washington D Georgetown is a Neighborhood located in the Northwest quadrant of Washington D John Shaw Billings ( April 12 1838 – March 11 1913) was a Librarian and Surgeon best known as the modernizer of the A key idea was that data could be coded numerically. Hollerith saw that if numbers could be punched in specified locations on a card, in the now familiar rows and columns, then the cards could be counted or sorted mechanically. On January 8, 1889, he was issued , claim 2 of which reads:
The herein-described method of compiling statistics, which consists in recording separate statistical items pertaining to the individual by holes or combinations of holes punched in sheets of electrically non-conducting material, and bearing a specific relation to each other and to a standard, and then counting or tallying such statistical items separately or in combination by means of mechanical counters operated by electro-magnets the circuits through which are controlled by the perforated sheets, substantially as and for the purpose set forth.

Hollerith built machines under contract for the US Census Bureau, which used them to tabulate the 1890 census in only one year. The United States Census Bureau (officially Bureau of the Census as defined in Title) is the government agency that is responsible for the United States Census  The 1880 census had taken eight years. Hollerith then started his own business in 1896, founding the Tabulating Machine Company. Most of the major census bureaus around the world leased his equipment and purchased his cards, as did major insurance companies. To make his system work, he invented the first automatic card-feed mechanism and the first key punch (i. A key punch is a device for entering data into Punched cards by precisely punching holes at locations designated by the keys struck by the operator e. a punch that was operated from a keyboard), which allowed a skilled operator to punch 200–300 cards per hour. There are many types of keyboard, usually differentiated by the Switch technology employed in their operation He also invented a tabulator. See also Unit record equipment The tabulating machine was a machine designed to assist in Tabulations. The 1890 Tabulator was hardwired to operate only on 1890 Census cards. See also Unit record equipment The tabulating machine was a machine designed to assist in Tabulations. To execute instructions a Computer 's Processor must generate the control signals used to perform the processor's actions in the proper sequence A wiring panel in his 1906 Type I Tabulator allowed it to do different jobs without having to be rebuilt (the first step towards programming). A plugboard, or control panel, was a device used to direct the operation of Unit record equipment, some cypher machines and some early computers These inventions were the foundation of the modern information processing industry.
In 1911, four corporations, including Hollerith's firm, merged to form the Computing Tabulating Recording Corporation (CTR). The Computing Tabulating Recording Corporation (CTR was incorporated on June 15 1911 in Endicott New York a few miles west of Binghamton  Under the presidency of Thomas J. Watson, it was renamed International Business Machines Corporation (IBM) in 1924. Thomas John Watson Sr ( February 17, 1874 &ndash June 19, 1956) was the American president of International Business Machines International Business Machines Corporation abbreviated IBM and nicknamed "Big Blue", is a multinational Computer Technology
