John Snow (1813 -1858) In a March 2003 survey by Hospital Doctor magazine, John Snow was voted the "greatest doctor" of all time, with Hippocrates (460 -370 BC) coming in second. While the poll was likely biased with over-representation of John Snow supporters, the findings do point to the increased prominence of Dr. Snow among contemporary physicians.

“Spatial thinking serves three purposes. It has (1) a descriptive function, capturing, preserving, and conveying the appearance of and relations among objects; (2) an analytic function, enabling an understanding of the structure of objects; and (3) an inferential function, generating answers to questions about the evolution and function of objects” National Research Council 2006 Matthew Bampton, USM
