Hollerith Electric Tabulating System (HETS)
The engineer Herman Hollerith designed his legendary counting machine in the mid-1880s, which was then used on a large scale for the first time in the US Census in 1890. This film explains how this came about and then uses the replica of history@IBM to explain how this important invention works.
