Tabulator

TabulatorCalculating machines performing basic arithmetic operations became quite widespread at the end of the 19th century. A new tendency was started by the introduction of a computing machine for simplifying data collection and processing in statistics. This machine was called TABULATOR.An American-German statistician Herman Hollerith was the first to introduce such machine. He decided to make the device being motivated by the U.S. census that was taking place at the beginning of the 1890s. The main principle of the device was to record data onto a punch card and then read it with the help of a special mechanism. Previously statistical calculations had to be done for several years. But with the help of the tabulator this could be done in several weeks. The next model of a statistical machine called tabulator used the electric current for registering data on the card. The device became very successful and was recognized worldwide. The first tabulators in Russia were bought in 1897, also for population census. Hollerith's company later merged with Computer Tabulation Recording. It got the name which now everybody knows - International Business Machines Corporation, or IBM for short.
