Tabulating Device

                                                            The Tabulating device  

                                         This machine was made by Herman Hollerith. 

in the 1880's-1890's the Tabulating machine was mainly used for the management for medical information throughout the country. This machine was used to record large amounts of information on punch cards. These cards where used to identify a person place or thing, these cards would have small holes punched on them that meant something. For example, one of these cards could have identified whether a person was male or female by just punching a few holes on the card. this with these cards you could find out a persons gender, age, are in which they live... Etc. Hollerith had worked on the census of 1880 and was intrigued in making the process faster, or in this case making it automated. This device was used in the 1890's census in order to gather and organize the nations information. While filling out a census, a person would punch a hole in the car in a specific area, given the information that the people wanted to put in, they would punch a hole in the designated area. The tabulating machine would then recognize where the whiles were and organize them in that order, where the holes where and what they stood for. without the tabulating device, the census would have taken 13+ years. Hollerith and his device where later contracted by IBM and allowed for the mass production of the device, it would later be used for hospitals,schools, companies, and the government.
