Alexander Mactier Pirrie 1882-1907
Alexander Mactier Pirrie came to the Sudan in 1906 to work with the Wellcome Research Laboratories in Khartoum. In 1907 he made an expedition to Southern Sudan that took him as far as the Shilluk territory. He returned to Khartoum with a fever that turned out to be kala-azar: Pirrie died within months.
During the expedition Alexander Pirrie made a lot of photographs to illustrate his descriptions of Sudanese peoples. Although he never had the chance to journey to the Nuba Mountains, he did find some Nuba in Renk. His measurements and notes were worked out by David Waterston in a Report upon the Physical Characters of some of the Nilotic Negroid Types which was published in the Third Report of the Wellcome Laboratories (1908).
