“…While preparing and assembling the pieces of a new hominin skull from the same Koobi Fora strata that had yielded robust australopithecines, Walker realized that it was a specimen of erectine Homo . This discovery demolished the “single‐species hypothesis” of the Michigan school and conclusively proved that multiple hominin species had lived side by side in the past (Leakey & Walker, ).…”

Alan Cyril Walker was born on August 23, 1938 in the industrial city of Leicester in the English Midlands. His relatives on both sides of his fam-Walker was diagnosed with pancreatic cancer 14 months before he died on November 20, 2017. During the last year of his life, he faced his impending death with high-hearted courage, good humor, and a degree of clinical detachment. All of us who knew him as a friend or benefited from his discoveries, knowledge, wisdom, and help will long remember his confident, East Midlands-accented voice and his sudden, slightly crooked grin. We mourn our loss, and perceive that our lives and our profession are diminished by his passing. ORCID Matt Cartmill

“…For reference, australopith brain volumes center around 450 ml, and modern Homo sapiens centers on 1330 ml: Holloway et al 2004). Eventually, Richard Leakey and Alan Walker formally capitulated and allocated all these East Turkana specimens to Homo erectus (Leakey and Walker 1976), despite the fact that the specimens (<1.6 Ma) were not only about a million years older than the Javan type material, but did not share any notable cranial morphologies with them.…”

“…Neanderthals, having attained a cultural capability associated with fully modern brain size, are judged probably equivalent to modern humans in intelligence and hence as belonging to our own species (1967, p. 96). By the second edition of Stages (1979), Brace had abandoned the single species hypothesis in its strict form, due to the demonstrated coexistence of Homo erectus and Australopithecus boisei (Leakey & Walker, ) and the discovery of A. afarensis remains pre‐dating stone tools. Incipient cultural development did not preclude the coexistence of multiple hominid taxa.…”

C. Loring Brace's writings on the concept of race have been among the most influential within anthropology. A review of the development of Brace's perspective on race shows that his philosophical approaches to fossil and modern human variation are consistent and integrated. Brace's views on race are compared with those of Ashley Montagu and Frank Livingstone, who also proposed eliminating "race" from anthropology, and with those of Stanley Garn and Alice Brues, who accepted "racial" subdivisions of humans. Carleton Coon's writings are more divergent; the aftermath of the publication of his Origin of Races highlights significant political tensions of the 1960s that intersected with scientific changes in anthropology emanating from the Evolutionary Synthesis. Recent forensic and "no race" positions are compared to explore their differences and the possibility of reconciliation, and the role of Brace and others in combating proposals of intellectual differences among human groups is discussed. While a spectrum of anthropological opinion regarding race exists, the commonalities are sufficient to allow valuable, united commentary emphasizing the complexity of modern human cultural and biological variation. Another of Brace's valuable contributions to the discipline has been as an historian, and a major focus of his historical research and writing has been an examination of the history of racial categorization.Both historical and scientific considerations led him to advocate an abandonment of the race concept. He was preceded in this view by Montagu (1941Montagu ( , 1942Montagu ( , 1951, who later became his coauthor for a general bioanthropology text (Brace & Montagu, 1965). The second edition of that text (1977) contains a chapter which details the history of the race concept, a chapter which set the foundation for Brace's later writings on the subject.In evaluating the development and influence of Brace's ideas on race, it is helpful to look at the ideas of some of his colleagues who wrote and conducted research in this area. In addition to Montagu, the main researchers targeted here will be Frank Livingstone, Stanley Garn, Carleton Coon, and Alice Brues. Montagu was a student of Boas at Columbia, Livingstone obtained his PhD from the University of Michigan, and Garn, Coon, and Brues all obtained Harvard degrees. The Harvard "bias" is easily explained. Prior to 1950, if one desired to be a biological anthropologist there was no other major institution in the United States in which to matriculate that had an established program 104
