The tabulating machine was an electromechanical machine designed to assist in summarizing information stored on punched cards. Invented by Herman Hollerith, the machine was developed to help process data for the 1890 U.S. Census. Later models were widely used for business applications such as accounting and inventory control.
Learn how Hollerith invented the punch card tabulating machine in 1888, which revolutionized the 1890 census and led to the formation of I.B.M. The device used punch cards, mercury contacts and dials to count and sort data.
Hollerith’s machine was a practical and critical hit. In 1890, the Franklin Institute of Philadelphia awarded Hollerith the prestigious Elliott Cresson Medal for his “machine for tabulating large numbers of statistical data.”
Learn how Herman Hollerith invented and used the first electronic tabulator to process and tabulate census data in 1890. See the components and operations of his system, such as punch cards, card reader, dials, and sorter.
Herman Hollerith (February 29, 1860 – November 17, 1929) was an American statistician, inventor, and businessman who developed an electromechanical tabulating machine for punched cards to assist in summarizing information and, later, in accounting.
In the late 1880s, inventor Herman Hollerith, who was inspired by train conductors using holes punched in different positions on a railway ticket to record traveler details, invented the recording of data on a machine-readable punched card. Hollerith’s cards were used for the 1890 US Census, which finished months ahead of schedule and under ...
