To what extent did the debate on the orangutan contribute to the global Enlightenment? This article focuses on the first 150 years of the introduction, dissection, and public exposition of the so-called ‘orangutan’ in Europe, between the 1630s, when the first specimens arrived in the Netherlands, and the 1770s, when the British debate about slavery and abolitionism reframed the boundaries between the human and animal kingdoms. Physicians, natural historians, antiquarians, philosophers, geographers, lawyers, and merchants all contributed to the knowledge of (...) the orangutan, while also reshaping the boundaries of humanity: when the human/animal divide narrowed, the divide between ‘savage’ and ‘civilized’ peoples crystallized, becoming wider than in any previous period.

Craniology – the practice of inferring intelligence differences from the measurement of human skulls – survived the dismissal of phrenology and remained a widely popular research program until the end of the nineteenth century. From the 1970s, historians and sociologists of science extensively focused on the explicit and implicit socio-cultural biases invalidating the evidence and claims that craniology produced. Building on this literature, I reassess the history of craniological practice from a different but complementary perspective that relies on recent developments (...) in the epistemology of measurement. More precisely, I identify two aspects of the measurement culture of nineteenth-century craniologists that are crucial to understand the lack of validity of craniological inference: their neglect of the problem of coordination for their presupposed quantification of intelligence and their narrow view of calibration. Based on my analysis, I claim that these methodological shortcomings amplified the impact of the socio-cultural biases of craniologists, which had a pervasive role in their evidential use of measurement. Finally, my argument shows how the epistemology of measurement perspective can offer useful tools in debates concerning the use of biological evidence to foster social discourse and for analyzing the relationship between theory, evidence, and measurement.

Since the nineteenth century, hominid palaeontology has offered critical information about prehistoric humans and evidence for human evolution. Human fossils discovered at a time when there was growing agreement that humans existed during the Ice Age became especially significant but also controversial. This paper argues that the techniques used to study human fossils from the 1850s to the 1870s and the way that these specimens were interpreted owed much to the anthropological examination of Stone, Bronze, and Iron Age skeletons retrieved (...) by archaeologists from prehistoric tombs throughout Europe. What emerged was the idea that a succession of distinct human races, which were identified using techniques such as craniometry, had occupied and migrated into Europe beginning in the Ice Age and continuing into the historic period. This marks a phase in the history of human palaeontology that gradually gave way to a science of palaeoanthropology that viewed hominid fossils more from the perspective of evolutionary theory and hominid phylogeny.

Between the last decades of the 18th century and the middle of the 19th century, something of paramount importance happened in the history of anthropology. This was the advent of a physical anthropology that was about the classification of ‘human races’ through comparative measurement. A central tool of the new trade was diagrams. Being inherently about relations in and between objects, diagrams became the means of defining human groups and their relations to each other – the last point being disputed (...) between the monogenists and the polygenists. James Cowles Prichard, a proponent of the comparative historical approach, was able to do without images in his pioneering Researches Into the Physical History of Man of 1813, but the third edition, which appeared in five volumes between 1836 and 1847, was richly illustrated with ‘ethnic types’ and skulls, including diagrams. What was happening is a process I engage with in detail for Samuel George Morton, who collected and distributed human skulls as lithographs in Crania americana (1839) and Crania aegyptiaca (1844). Along with the paper skulls travelled detailed instructions of how to look at them through a set of lines and to set their individual parts in relation to each other as well as to those of other types. Drawing on Johann Friedrich Blumenbach and Peter Camper, the Crania thus played a pivotal role in establishing what I call a diagrammatics of race – a diagrammatics that became overtly political with Types of Mankind (1854), which was written in Morton's honour by Josiah Nott and George Gliddon.
