who initiated the storage of information on punched cards
Punched card Semyon Korsakov was reputedly the first to use the punched cards[citation needed] in informatics for information store and search. Korsakov announced his new method and machines in September 1832; rather than seeking patents, he offered the machines for public use.[6][7]

Punched card Charles Babbage proposed the use of "Number Cards", "pierced with certain holes and stand opposite levers connected with a set of figure wheels ... advanced they push in those levers opposite to which there are no holes on the card and thus transfer that number" in his description of the Calculating Engine's Store.[8]
Herman Hollerith Hollerith initially did business under his own name, as The Hollerith Electric Tabulating System, specializing in punched card data processing equipment.[14] He provided tabulators and other machines under contract for the Census Office, which used them for the 1890 census. The net effect of the many changes from the 1880 census: the larger population, the data items to be collected, the Census Bureau headcount, the scheduled publications, and the use of Hollerith's electromechanical tabulators, was to reduce the time required to process the census from eight years for the 1880 census to six years for the 1890 census.[15]
