To count data in the 1890 census, which could not have been completed on time to meet the requirements of the constitution using traditional hand methods. The tabulator also controlled a sorter so that cards could be separated for appropriate further processing later on other tabulators.
Invented by Herman Hollerith, the machine was developed to help process data for the 1890 U.S. Census.

Herman Hollerith founded the Computing-Tabulating-Recording Company, or CTR. In 1924 CTR became the International Business Machines Corporation.
The Hollerith desk, developed by Herman Hollerith in the late 19th century, was an early data processing machine used for sorting and tabulating data from punched cards. It revolutionized the handling of census data and significantly improved efficiency in data processing. Hollerith's innovations laid the groundwork for the development of modern computing and the founding of IBM. The desk operated by reading the holes in the punched cards to perform calculations and generate reports quickly.
Herman Hollerith invented the tabulating machine to support work in the US 1890 census, tabulating numbers for the count of population in the country.

Herman Hollerith is the founder of The Tabulating Machine Company in 1896 which later became the International Business Machine in 1924, after a few mergers.
Herman Hollerith founded the Computing-Tabulating-Recording Company, or CTR. In 1924 CTR became the International Business Machines Corporation.
It was invented in 1929.
That company eventually became IBM.
The tabulating machine was an electromechanical machine designed to assist in summarizing information and, later, accounting and was developed by Herman Hollerith, the founder of IBM. The modern version is a calculator.
Herman Hollerith was likely the person you're looking for. He invented and was awarded patents for a series of machines that used punched holes for a method of recording data. The true ancestor of our punch cards we think of today such as the IBM type 80. Hope this helps!
