From 1895 inventor Herman Hollerith wooed the New York Central Railroad as a commercial customer for his tabulating machines. This small paper card records his success. It reports that in April 1904, key punch operators at the Central punched a total of 428,502 cards, averaging 258 cards per clerk per hour. The record for one clerk was 70,535 cards punched, averaging 413 cards per hour.
