What was the Hollerith machine used for?
The tabulating machine was an electromechanical machine designed to assist in summarizing information stored on punched cards. Invented by Herman Hollerith, the machine was developed to help process data for the 1890 U.S. Census.

What concept does Herman Hollerith use in tabulating?
Herman Hollerith’s punched card tabulator transformed the census process—and information processing in general—beginning with the 1890 US census. The machine was able to collect and count data more rapidly and accurately than manual processes had allowed in the past.
What machine did Hollerith invented?
tabulating machine
Herman Hollerith, (born February 29, 1860, Buffalo, New York, U.S.—died November 17, 1929, Washington, D.C.), American inventor of a tabulating machine that was an important precursor of the electronic computer.
Why is Hollerith called as father of information processing?
Herman Hollerith is widely regarded as the father of modern automatic computation. He chose the punched card as the basis for storing and processing information and he built the first punched-card tabulating and sorting machines as well as the first key punch, and he founded the company that was to become IBM.
How did Herman Hollerith contribution to the computer?
What did Herman Hollerith accomplish?
Hollerith’s electric counting machines were a great success. In addition to earning the inventor a medal at the 1893 Chicago World’s Fair, the tabulating machines appreciably reduced tabulation time for the 1890 census while providing more statistics at a lower cost for processing.
What are the primary components of Hollerith’s tabulator?
Herman Hollerith’s tabulator consisted of electrically-operated components that captured and processed census data by “reading” holes on paper punch cards. The primary components of the system are explained below. A pantograph used to create punch cards.
What did Herman Hollerith do for the Census Bureau?
Herman Hollerith’s impressive results earned him the contract to process and tabulate 1890 census data. Modified versions of his technology would continue to be used at the Census Bureau until replaced by computers in the 1950s.
How does a Hollerith card reader work?
Each Hollerith tabulator was equipped with a card reading station. The manually-operated card reader consisted of two hinged plates operated by a lever (similar to a waffle iron). Clerks opened the reader and positioned a punched card between the plates.
When did Herman Hollerith invent electronic tabulation?
Modified versions of his technology would continue to be used at the Census Bureau until replaced by computers in the 1950s. Learn more about Herman Hollerith and his inventions at our January 2016 Webpage commemorating his 1889 patent for electronic tabulation.
