charles babbage
I believe he was a mathematician who invented the mechanical adding machine in 1642.
The Turing machine was invented in 1936 by British mathematician Alan Turing.
the mechanical reaper was invented in Virginia.
The Difference Engine and Analytical Engine were invented by Charles Babbage, an English mathematician and inventor. He designed the Difference Engine in the 1820s to automate polynomial calculations and later conceptualized the Analytical Engine in the 1830s as a more general-purpose mechanical computer. Although neither machine was completed during his lifetime, Babbage's designs laid the groundwork for modern computing.
In 1642 Blaise Pascal (a famous French mathematician) invented an adding machine based on mechanical gears in which numbers were represented by the cogs on the wheels.The abacus or counting frame was a device used for calculations that is probably 5000 years old and is still used throughout Asia and Africa.
In 1642 Blaise Pascal who was both a mathematician and a philosopher invented a very basic adding machine
The Threshing Machine was invented by Andrew Meikle, who was a Scottish Mechanical Engineer. The machine was invented in 1784 for the purposes of separating grain from stalks and husks of plants.
The Leibniz calculating machine was invented by Gottfried Wilhelm Leibniz. Leibniz was a German mathematician who was born in the Holy Roman Empire on July 1, 1646.
I am not sure anyone invited it. It was invented by the French mathematician, Blaise Pascal.
The thrashing machine, or, in modern spelling, threshing machine (or simply thresher), was invented in 1886 by Scottish mechanical engineer Andrew Meikle.
Blaise Pascal invented the ancestor of the calculator.
He invented the first mechanical adding machine.
