Hollerith tabulating machine

In 1889, Dr. Herman Hollerith received the first US patents for a tabulating machine (No. 395,781, -2, -3) which he called the "Art of Compiling Statistics". His system was designed to record separate statistical items by means of combinations of holes in a punched card to carry information about an individual. The information contained on numerous cards could then be tallied by passing the cards through electrical counters operated by electromagnets. The patent described its application in compilation of the statistics of the population for the U.S. Census. The first extensive application of this system was for the 1890 census counting data items such as age, sex, occupation, etc., of which tallies could be made in combinations such as how many males of certain ages.
