Detailed explanation-1: -In an 1888 test against two competing systems, Hollerith’s system won easily, tabulating the census data for over 10, 000 people in 5.5 hours, compared with 44.5 and 55.5 hours for his competitors.
Detailed explanation-2: -Hollerith astounded Census Bureau officials by completing the task in just 5.5 hours! Herman Hollerith’s impressive results earned him the contract to process and tabulate 1890 census data.
Detailed explanation-3: -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.
Detailed explanation-4: -The tabulator is shown at the center in the photograph. Hollerith’s tabulating system won a gold medal at the 1889 World’s Fair in Paris, and was used successfully the next year to count the results of the 1890 Census. His inventions formed the starting point of a company that would become IBM.
Detailed explanation-5: -Hollerith’s device revolutionized census tabulation. The Census Office leased a fleet of the machines for the 1890 census count, which finished months ahead of schedule and far under budget. In 1896, Hollerith founded the Tabulating Machine Company.
