Herman Hollerith then at the U.S. Census bureau devised a tabulating system that included cards ([[Punched_card|PayuHollerith card, later Punched card]]), a punch for holes in them representing data, a tabulator and a sorter, The system was tested in computing mortality statistics for the city of Baltimore. In the first commercial electronic data processing Hollerith machines were used to compile the data accumulated in the 1890 U.S. Census of population.<ref>{{cite web

The punch-card and tabulation machine business remained the core of electronic data processing until the advent of electronic computing in the 1950s (which then still rested on punch cards for storing informatio=information).<ref>{{cite_web}}={{0657652301}}cite web
