Ma page utilisateur en Français

Hi,

I've been collecting vintage mechanical calculators (machines, books, etc...) for a few years now and I've decided to share my new found knowledge with the Wikipedia community.

Born in France, I am a naturalized US citizen, so whenever I create or modify an article I try to modify both the French and English versions in identical ways.

Here are a few pages that I have created or worked on: Hope to read some of your articles soon ....
 * Arithmaurel
 * Arithmometer
 * Busicom
 * Comptometer
 * Leibniz wheel
 * Odhner Arithmometer
 * Blaise Pascal
 * Pascal's calculator
 * Pinwheel calculator
 * The Millionaire Calculator
 * Thomas de Colmar
 * Wilhelm Schickard
