Through a series of merges the company eventually became the IBM Corporation.Ĭalculating device - вычислительное устройство Later Hollerith left the Census Bureau and established his own tabulating machine company. He built one machine to punch the holes and others to tabulate the collected data. Hollerith invented a means of coding the data by punching holes into cards. Herman Hollerith, a young statistician from the US Census Bureau successfully tabulated the 1890 census. He never finished this work, but many of his ideas were the basis for building today's computers.īy the early part of the twentieth century electromechanical machines had been developed and were used for business data processing. This machine, which Babbage showed at the Paris Exhibition in 1855, was an attempt to cut out the human being altogether, except for providing the machine with the necessary facts about the problem to be solved. In 1830 Charles Babbage, a gifted English mathematician, proposed to build a general-purpose problem-solving machine that he called "the analytical engine". The first real calculating machine appeared in 1820 as the result of several people's experiments. Henry Briggs used Napier's ideas to produce logarithm tables which all mathematicians use today.Ĭalculus, another branch of mathematics, was independently invented by both Sir Isaac Newton, an Englishman, and Leibnitz, a German mathematician. J.Napier, a Scotsman, invented a mechanical way of multiplying and dividing, which is now the modern slide rule works.

People went on using some form of abacus well into the 16 th century, and it is still being used in some parts of the world because it can be understood without knowing how to read.ĭuring the 17 th and 18 th centuries many people tried to find easy ways of calculating. This, in fact, is why today we still count in tens and multiples of tens. The very first calculating device used was the ten fingers of a man's hands. Let us take a look at the history of computers that we know today.
