This principle was first proposed in 1744 by the French cosmologist Pierre-Louis Moreau de Maupertuis (1698-1759, after settling in Basel, Switzerland), who declared in Essai de cosmologie (1750; “Essay on Cosmology”) that “in all the changes that take place in the universe, the sum of the products of each body multiplied by the distance it moves and by the speed with which it moves is the least [that is] possible.”<ref>https://www.britannica.com/biography/Pierre-Louis-Moreau-de-Maupertuis#ref9124</ref>
