The theory of indifference curves was developed by Francis Ysidro Edgeworth, who explained in his book " Mathematical Psychics: an Essay on the Application of Mathematics to the Moral Sciences ”, 1881, the mathematics needed for its drawing ; later on, Vilfredo Pareto was the first author to actually draw these curves, in his book " Manual of Political Economy ", 1906 ; and others in the first part of the 20th century.
