Hollerith 1890 tabulating machine with sorting box. [a] Hollerith punched card. The tabulating machine was an electromechanical machine designed to assist in summarizing information stored on punched cards. Invented by Herman Hollerith, the machine was developed to help process data for the 1890 U.S. Census.
To process these punched cards, sometimes referred to as "Hollerith cards", he invented the keypunch, sorter, and tabulator unit record machines. [10] [11] These inventions were the foundation of the data processing industry. The tabulator used electromechanical relays to increment mechanical counters. Hollerith's method was used in the 1890 ...
Herman Hollerith (February 29, 1860 – November 17, 1929) 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.
The company was formed in 1902 as The Tabulator Limited, after Robert Porter obtained the rights to sell Herman Hollerith's patented machines from the US Tabulating Machine Company (later to become IBM). During 1907, the company was renamed the "British Tabulating Machine Company Limited".
The use of punched cards for recording and tabulating data was first proposed and used by Semyon Korsakov around 1805. In 1832 Charles Babbage proposed using similar cards to program and to store computations for his calculating engine. Punched card technology was further developed for data-processing by Herman Hollerith from the 1880s.
Sorting cards became an issue during the 1900 agricultural census, so Herman Hollerith's company developed the 1901 Hollerith Automatic Horizontal Sorter, [4] a sorter with horizontal pockets. [ 5 ] In 1908, he designed the more compact Hollerith 070 Vertical Sorting Machine [ 6 ] that sorted 250 cards per minute.
Commissioned as a publicity stunt by THQ (a video game publisher that has since gone out of business) for Queen Elizabeth II, this gold-plated Wii stands out as a literal gem in gaming history.
In 1890, the government began leasing tabulating machines from Herman Hollerith's Tabulating Machine Company, to more efficiently, expansively, and accurately produce the national census. In 1900, Hollerith raised the lease pricing. This led the newly formed U.S. Census Bureau to seek other suppliers under its new director, Simon North, in 1903.
