A scientist or specialist who measures and studies the dimensions and structure of human skulls.
From cranio- + -metrist (one who practices measurement, from Greek metron). The term emerged in 19th-century anthropology as a distinct professional specialty.
Early craniometrists were like the 'skull detectives' of their time, convinced they could read personality and intelligence from bone measurements—a cautionary tale about how measurement can masquerade as science.
