Pascal's calculator (also known as the arithmetic machine or Pascaline) is a mechanical calculator invented by Blaise Pascal in 1642. Pascal was led to develop a calculator by the laborious arithmetical calculations required by his father's work as the supervisor of taxes in Rouen . [ 2 ]
For 40 years, [58] the arithmometer was the only mechanical calculator available for sale and was sold all over the world. By 1890, about 2,500 arithmometers had been sold [59] plus a few hundreds more from two licensed arithmometer clone makers (Burkhardt, Germany, 1878 and Layton, UK, 1883). Felt and Tarrant, the only other competitor in true ...
The arithmometer (French: arithmomètre) was the first digital mechanical calculator strong enough and reliable enough to be used daily in an office environment. This calculator could add and subtract two numbers directly and could perform long multiplications and divisions effectively by using a movable accumulator for the result.
The Arithmometer, invented in 1820 as a four-operation mechanical calculator, was released to production in 1851 as an adding machine and became the first commercially successful unit; forty years later, by 1890, about 2,500 arithmometers had been sold [16] plus a few hundreds more from two arithmometer clone makers (Burkhardt, Germany, 1878 ...
In St. Petersburg, Russia, Wilgott Theophil Odhner invented his arithmometer in 1874 and in 1890 [7] it became the first pinwheel calculator to be mass-manufactured. Its industrial production started in Odhner's workshop: W.T. Odhner, Maschinenfabrik & Metallgiesserei and then moved to the Odhner-Gill factory (фабрика Однера ...
Blaise Pascal and Wilhelm Schickard were the two original inventors of the mechanical calculator in 1642. [1] For Pascal, this was an adding machine that could perform additions and subtractions directly and multiplication and divisions by repetitions, while Schickard's machine, invented several decades earlier, was less functionally efficient ...
Pascal invented his machine in 1642. In 1642, while still a teenager, Blaise Pascal started some pioneering work on calculating machines and after three years of effort and 50 prototypes [18] he invented a mechanical calculator. [19] [20] He built twenty of these machines (called Pascal's calculator or Pascaline) in the following ten years. [21]
The first model of the Arithmometer was introduced in 1820, and as a result Thomas was made Chevalier of the Legion of Honor in 1821. [2] [3] Despite this, Thomas spent all of his time and energy on his insurance business, therefore there is a hiatus of more than thirty years in before the Artitometer's commercialization in 1852.
