Today’s picture was taken in 1919, and shows an office worker operating a tabulating machine. The machine was developed by the Census Bureau to help count large numbers of cards. It is interesting that complex mechanical computers were in development all the way back in the 1850′s to try and help the Census Bureau with the large task of counting and tabulating the census.
