The first automatic data processing system. Developed by Herman Hollerith, a Census Bureau statistician, the machine was first used to count the U.S. census of 1890.

In 1911, his company merged with another company that was later renamed IBM. Following is the sequence of steps used to count the 1890 census. See punch card.
