In 1889, a mechanical engineer named Herman Hollerith persuaded the United States government to use machine‑readable paper punch cards and electric counting machines to conduct the national Census, saving the U.S. Treasury about $5 million in the costs of handling data for 62 million people.

By 1891 Hollerith was designing machines to be used in censuses in Canada, Norway, and Austria, as well as by railroads to tabulate fare information.

As a result, Hollerith’s fledgling company quickly became part of the growing data landscape, and eventually, in 1924, it became the International Business Machines Corporation, or IBM.
