A Pascaline signed by Pascal in 1652 Top view and overview of the entire mechanism. This version of Pascaline was for accounting. [1]The pascaline (also known as the arithmetic machine or Pascal's calculator) is a mechanical calculator invented by Blaise Pascal in 1642.
Blaise Pascal [a] (19 June 1623 – 19 August 1662) was a French mathematician, physicist, inventor, philosopher, and Catholic writer. Pascal was a child prodigy who was educated by his father, a tax collector in Rouen .
Two decades after Schickard, in 1642, Blaise Pascal invented another mechanical calculator with better (but still not perfect) tens-carry. [2] Co-opted into his father's labour as tax collector in Rouen, Pascal designed the calculator to help in the large amount of tedious arithmetic required; [3] it was called Pascal's Calculator or Pascaline.

View through the back of Pascal's calculator. 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.
Around 1640, Blaise Pascal, a leading French mathematician, constructed a mechanical adding device based on a design described by Greek mathematician Hero of Alexandria. [16] Then in 1672 Gottfried Wilhelm Leibniz invented the Stepped Reckoner which he completed in 1694. [17]
French polymath Blaise Pascal invented the mechanical calculator. [23] Called machine arithmétique , Pascal's calculator and eventually Pascaline , its public introduction in 1645 started the development of mechanical calculators first in Europe and then in the rest of the world.
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 ...
