The machine also included a sorter, which could select a particular group of cards based on multiple criteria. Before the census, the machine was first tested in several smaller capacities, including the health departments of Baltimore and New York, and the U.
War Department, which marked the first federal use of the device. By the time the census rolled around, the tabulating machine was finely tuned and ready to go. Without the inventions, experts had estimated, the census would have taken 13 years to fully tabulate. With the device in place, the tabulation finished ahead of schedule and under budget. Hollerith then adapted his invention to work in the mercantile areas where years later, it would also give good results. I n Herman Hollerith founds the company Tabulating Machine with which he commercializes his invention and which, together with three technology companies, would become in in the International Business Machine Corporation, known worldwide as IBM.
The function of the tabulating machine was at the beginning, to tabulate the U. When the process was complete, an alarm sounded, and another card had to be inserted. This allowed employees to group the cards according to the information they provided. Its operation was based on the use of cards that could serve as electrical insulators, with the exception of places where these were pierced.
The machine was able to read the information on the cards and process the data inserted. How to cite this article? Tabulating machine. Informatics Tabulating machine. Who invented it?

Description During the s the engineer Herman Hollerith devised a set of machines for compiling data from the United States Census.
Hollerith's tabulating system included a punch for entering data about each person onto a blank card, a tabulator for reading the cards and summing up information, and a sorting box for sorting the cards for further analysis.
The tabulator is shown at the center in the photograph. Hollerith's tabulating system won a gold medal at the World's Fair in Paris, and was used successfully the next year to count the results of the Census. His inventions formed the starting point of a company that would become IBM. Nominate this object for photography. See our privacy policy. Collections Search Search for
