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. Later models were widely used for business applications such as accounting and inventory control.
Herman Hollerith (February 29, 1860 – November 17, 1929) was an 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 ...
Starting at the end of the nineteenth century, well before the advent of electronic computers, data processing was performed using electromechanical machines collectively referred to as unit record equipment, electric accounting machines (EAM) or tabulating machines. [1][2][3][4] Unit record machines came to be as ubiquitous in industry and ...
IBM 407. A 407 at U.S. Army 's Redstone Arsenal in 1961. The IBM 407 Accounting Machine, introduced in 1949, was one of a long line of IBM tabulating machines dating back to the days of Herman Hollerith. It had a card reader and printer; a summary punch could be attached. Processing was directed by a control panel.
Georgia now becomes the only state in the U.S. to implement such a requirement as part of the normal process of tabulating machine-recorded results, according to Gowri Ramachandran, the director ...
British Tabulating Machine Company. The British Tabulating Machine Company (BTM) was a firm which manufactured and sold Hollerith unit record equipment and other data-processing equipment. During World War II, BTM constructed some 200 "bombes", machines used at Bletchley Park to break the German Enigma machine ciphers.
The system included the whole set of machines, necessary for tabulating, namely, the electric card punch, card verifier, sorting machine, and printing tabulator. Printing tabulator Hollerith's tabulators were non-printing, displaying numbers on a row of mechanical counters.
Hollerith Electronic Computer. The Hollerith Electronic Computer (HEC) was produced by the British Tabulating Machine Company (BTM) and was based on a design by Professor Andrew Booth of Birkbeck College, London. [1] It was Britain's first mass-produced business computer. The prototype first worked at the end of 1951. [1]
