Herman Hollerith, one of the godfather of computers, developed a mechanical tabulator based on punched cards in order to rapidly tabulate statistics from millions of pieces of data. He died on November 17, 1929 of a heart attack and was buried in the Oak Hill Cemetery.
Large-scale automated data processing of punched cards was performed for the U.S. Census in 1890 by tabulating machines designed by Herman Hollerith and manufactured by the Computing Tabulating Recording Corporation, which later became IBM.
