Herman Hollerith/Inventions

Herman Hollerith is the father of modern machine data processing. His invention of the punched card machine marked the beginning of the automatic data processing age. Whereas punched cards had previously been used to control looms, Hollerith now used them to store data.

How did Hollerith tabulating machine work?

A pantograph used to create punch cards. To begin tabulating data, census information had to be transferred from the census schedules to paper punch cards using gang punches and pantographs. Using this equipment, Census Bureau clerks “punched” each card to represent specific data on the census schedule.

What is Hollerith machine?

A Hollerith machine is a specific type of electromechanical design that served as an information-processing resource throughout the early 20th century. The machine used a system of electrical and mechanical signals, and a set of wires positioned over pools of mercury, to incrementally count data on paper punch cards.
