It was Wilhelm Schickard, who built the first calculator in 1623, this machine has been destroyed by a fire. He described the machine in a letter to Keppler 1624. Schickard's drawings of the machine have been lost for centuries. They have been discovered in 1960. Engineers built a working replika based on these drawings.

Thank you Roland, indeed it was Wilhelm Schickard who invented the first calculating machine but never used at the time because it was not really perfect...
Only Pascal's machine, although later, was used by many people and was marketed with some success.
And its operation was renowned for being excellent and flawless (today we would rather say "bug")
