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.
Its production debut of 1851 [2] launched the mechanical calculator industry [4] which ultimately built millions of machines well into the 1970s. For forty years, from 1851 to 1890, [7] the arithmometer was the only type of mechanical calculator in commercial production, and it was sold all over the world. During the later part of that period ...
In 1820, Thomas de Colmar patented the Arithmometer. It was a true four operation machine with a one digit multiplier/divider (The Millionaire calculator released 70 years later had a similar user interface [79]). He spent the next 30 years and 300,000 Francs developing his machine. [80]
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 ...

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 ...
He also designed a pinwheel calculator in 1775. [7] – Johann-Helfrich Müller built a machine very similar to Hahn's machine in 1783. – Thomas de Colmar invented his Arithmometer in 1820 but it took him 30 years of development before it was commercialized in 1851. It was manufactured until 1915.
Frank Stephen Baldwin (April 10, 1838 – April 8, 1925) was an American who invented a pinwheel calculator in 1875. He started the design of a new machine in 1905 and was able to finalize its design with the help of Jay R. Monroe who eventually bought the exclusive rights to the machine and started the Monroe Calculating Machine Company to manufacture it.
