La Préface

Between the time of carefully written letters and the time of computers, the Museum of the Writing and Calculating Machine invites you to discover old machines, to listen to them working, and to observe their mechanism
It is impossible to list all the brands of these typewriters, but some of them may evoke memories: Japy, Hermes, Olivetti, Olympia, Remington, Underwood...
And what about the calculating instruments presented: from abacuses to Neper's sticks through Thomas de Colmar's or Payen's arithmometers, you will find the famous slide rule which, in the twinkling of an eye, proves to be as precise as our calculators
Among these different instruments, some of them will even allow those who do not have a knack for math to understand some calculation methods!
