 These worked in tandem with scientific discourses that sought to classify and categorize and, in so doing, became methods of normalization.The concept of the "norm" developed in this time period, and is signaled in the work of the Belgian statistician, sociologist, mathematician, and astronomer Adolphe Quetelet, who wrote in the 1830s of l'homme moyen – the average man.Quetelet postulated that one could take the sum of all people's attributes in a given population (such as their height or weight) and find their average and that this figure should serve as a norm toward which all should aspire.
