1900 Hollerith Tabulator and Sorter

The Census Bureau used versions of the Hollerith Tabulators (left) and Sorters (right) to tabulate census data from 1890 until replaced by computers. This tabulator, used following the 1900 census, displayed data "read" from punch cards on the tabulation dials.

Year: 1900
