Vilfredo Pareto
![Pareto in the 1870s](https://upload.wikimedia.org/wikipedia/commons/f/fd/Vilfredo_Pareto_1870s2.jpg)
He introduced the concept of Pareto efficiency and helped develop the field of microeconomics. He was also the first to claim that income follows a Pareto distribution, which is a power law probability distribution. The Pareto principle was named after him, and it was built on his observations that 80% of the wealth in Italy belonged to about 20% of the population. He also contributed to the fields of sociology and mathematics. Provided by Wikipedia
