Camper Angle, defined by the 18th-century Dutch physician and biologist Petrus Camper, by two lines on the profile of a human face: one from the most prominent point of the forehead to the anterior part of the alveolar rim of the upper jaw and the other horizontal from the ear to the wing of the nose. Camper determined that the Europeans had an angle of 80 degrees while the Africans only 70. The Nazis used this angle to select Aryan individuals.
