# Mathematician:Giuseppe Peano

## Contents

## Mathematician

Italian mathematician who contributed significantly to the founding of the fields of mathematical logic and set theory.

Invented many of the symbols used today in these fields.

Worked on the axiomatization of mathematics, and contributed greatly towards the method of mathematical induction.

Invented Latino sine flexione, a simplified version of Latin, intended as an international language. Peano's view was that Latin was already a universally-used international language, and there was no need to invent further such languages.

The recent ubiquity of English in its many forms has since rendered his argument obsolete.
