The history of computer dates back a lot longer than the 1900s, in fact computers have been around for over 5000 years.In ancient time a "computer", (or "computor") was a person who performed numerical calculations under the direction of a mathematician.
Some of the better known devices used are the Abacus or the Antikythera mechanism.
Around 1725 Basile Bouchon used perforated paper in a loom to establish the pattern to be reproduced on cloth. This ensured that the pattern was always the same and hardly had any human errors.
Later, in 1801, Joseph Jacquard (1752 - 1834), used the punch card idea to automate more devices with great success.
The First computers?
Charles Babbage's. (1792-1871), was ahead of his time, and using the punch card idea he developed the first computing devices that would be used for scientific purposes. He invented the Charles Babbage's Difference Engine, which he begun in 1823 but never completed. Later he started work on the Analytical Engine, it was designed in 1842.Babbage was also credited with inventing computing concepts such as conditional branches, iterative loops and index variables.
Ada Lovelace (1815-1852), was a colleague of Babbage and founder of scientific computing.
Many people improved on the Babbage inventions, George Scheutz along with his son, Edvard Scheutz, began work on a smaller version and by 1853 they had constructed a machine that could process 15-digit numbers and calculate fourth-order differences.
On of the first notable commercial use, (and success), of computers was the US Census Bureau, which used punch-card equipment designed by Herman Hollerith to tabulate data for the 1890 census.
To compensate for the cyclical nature of the Census Bureau's demand for his machines, Hollerith founded the Tabulating Machine Company (1896), which was one of three companies that merged to form IBM in 1911.
