Description:

Who: Herman Hollerith, a former employee of the Census Bureau.
What: The Hollerith Machine was one of the earliest tabulating machines that played an important role in computing history. It was based on the use of punch cards to process and tabulate data, thus enhancing efficiency as well as speed in information processing. The machine had essential parts of a pantograph to make punch cards, card reader, tabulator dials used for data recording and the sorting table.
When: Hollerith’s machine was first applied in a federal government department for 1890 U.S Census data and proved critical herein.
What is the significance of this in CS history? The Hollerith Machine was a great development of technology in the field of data processing. It was a forerunner of modern computing that facilitated the quick and effective processing of large amounts. Hollerith’s machine was a success, which led to the establishment of the Tabulating Machine Company that later became International Business Machines (IBM) and one of pioneers in computing technology.
