Invented by Herman Hollerith, the machine was developed to help process data for the 1890 U.S. Census.

to help his father
He built a "counting" machine for the US census using punched cards and electric contacts. In 1896 he started the Tabulating Machine Company. In 1911, his & 3 other companies formed the Computing Tabulating Recording Company, In 1924 it was renamed International Business Machines Corp (IBM).
Herman Hollerith founded the Computing-Tabulating-Recording Company, or CTR. In 1924 CTR became the International Business Machines Corporation.
The abacus (unknown), slide rule (The Reverend William Oughtred and others ), Pascaline (Pascal), the Stepped Reckoner (German mathematician Gottfried Wilhelm Leibniz), the analytical engine (English engineer Babbage) and the tabulating machine (Herman Hollerith). Finally tabulators such as the 1949 IBM 407 and the 1952 Remington Rand 409 were made and Tabulating machines continued to be used well after the introduction of commercial electronic computers in the 1950s.

IBM
to help his father
IBM was originally called CTR (Computing Tabulating Recording Corporation) before changing to IBM in 1924. The original name comes from the 3 previous companies that were merged together in 1911 to form CTR. These companies were the International Time Recording company, the Tabulating Machine company, and the Computing Scale Corporation.
