Morton-Tiedemann-Gould

Speaking of Race

In this episode we talk with Paul Wolff Mitchell, of the Department of Anthropology at the University of Pennsylvania, about the skull measurements of 19th century founding father of the American School of Anthropology, Samuel George Morton. Morton used his skull measurements to provide scientific support for polygenism (multiple origins of human races), slavery, and the ranking of races (as we discussed in earlier episodes: Monogenism and Polygenism and Morton and Gould--Polygeny Side B). Mitchell has analyzed Morton’s handwritten notes in an attempt to shed further light on the issue of Morton’s bias which was initially raised by Stephen Jay Gould in his 1978 article (Gould, 1978) and elaborated in his book, The Mismeasure of Man (Gould, 1981, 1996). Mitchell uses Morton’s contemporary, Friedrich Tiedemann, as an exemplar of someone using cranial measurements to come to the exact opposite conclusion, that the races were equal (Tiedemann, 1836).
