Thibaudeau classification
In typography, the Thibaudeau Classification is a way to group typefaces into four general families, according to shape and serif character. Invented in 1921 by the French typographer Francis Thibaudeau, it was expanded by Maximilien Vox in 1954, and again in 1962 by Association Typographique Internationale into the VOX-ATypI classification of 11 families. The Thibaudeau system is nevertheless still beneficial in that it is simple to comprehend. Thibaudeau later supplemented the classification by adding the category of the Écritures and the Fantaisies.Elzévirs
