 HOLLERITH'S MACHINE

In 1885, Herman Hollerith, a census statistician with U.S Census Bureau, developed a machine run on electricity for the first time for calculating and recording data. Hollerith's machine was capable of  reading both numbers and letters, processing and giving out letters and numbers in the desired form.

The input was in the form of punched cards and the combinations of hole formed the "code" of input data. He invented a machine that punched holes on cards which was called "Tabulator". This machine processed the cards by detecting holes by electronic contents and also performed the function of selecting and sorting the cards this machine solved the information of 60 million people of 1890 U.S. census just in three years. in 1896, 

Hollerith established his own company called Tabulating Machine company (TMC). The same company is today known as "INTERNATIONAL BUSINESS MACHINES CORPORATION" (IBM)
