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 article explains the device’s design, function and impact on information technology.
