One of the greatest mathematicians of the 18th century, Leonhard Euler was responsible for important advancements in a number of different areas, especially number theory. There are Euler theorems, Euler numbers and Euler formulas in a different fields, each distinct because Euler contributed to so many specialties.
In the field of philosophy, Leonhard Euler was the first to systematically employ logic diagrams to map out the structure of logical statements and arguments. Circles to represent classes and diagram syllogisms had earlier been used by Leibniz and others, but Euler was the first to explain in detail how the circles can and should be used. This understanding would later be expanded upon by John Venn and such diagrams are now known as Venn Diagrams.
