Biography
Vilfredo Pareto was born in 1848 in Paris, the epicenter of people's revolutions of the year. His father was an Italian civil engineer, his mother a French woman. In his childhood, Pareto lived in a middle-class environment, receiving a high standard of education.
In 1870 he gained an engineering degree from what is now the Polytechnic University of Turin. His thesis was entitled "The Fundamental Principles of Equilibrium in Solid Bodies". His later interest in equilibrium analysis in economics and sociology can be traced back to this paper.
For some years after graduation, he worked as a civil engineer, first for the state-owned Italian Railway Company and later in private industry.
In 1886 he became a lecturer on economics and management at the University of Florence. His stay in Florence was marked by political activity, much of it fuelled by his own frustrations with government regulators.
In 1889, after the death of his parents, Pareto changed his lifestyle: he quit his job, and married a Russian, Alessandrina Bakunin. He began writing numerous polemical articles against the government, causing him much trouble.
In 1893 he was appointed as a lecturer in economics at the University of Lausanne in Switzerland where he remained for the rest of his life.
In 1906 he made the famous observation that twenty percent of the population owned eighty percent of the property in Italy, later generalised by Joseph M. Juran and others into the so-called Pareto principle (also termed the 80-20 rule) and generalised further to the concept of a Pareto distribution.
He died at Lausanne, Switzerland, in 1923.
Pareto works and legacy
The Pareto index is a measure of the inequality of income distribution.
The Pareto chart is a special type of histogram, used to view causes of a problem in order of severity from largest to smallest. It is a statistical tool that graphically demonstrates the Pareto principle or the 80-20 rule.
In his Trattato di Sociologia Generale (or The Treatise on General Sociology) first published in English under the title Mind and society, he put forward the first social cycle theory in sociology. His theories influenced Benito Mussolini and the development of Italian fascism.
