Lecture, "How Did They Make Those Maps?", given by Dr. Robert Karrow on February 13, 2011 at the McClung Museum. For most people looking at a world map from 1500 that shows land masses more or less the way we know they look, the first question to come to mind is likely to be "How did they do that?" This talk will try to answer that question by examining the basics of earth measurement from antiquity to the 19th century. 

Robert W. Karrow, Jr. is Curator of Maps and Curator of Special Collections at the Newberry Library in Chicago. He has a doctorate in history, has published and lectured widely in the history of cartography and has a particular interest in the history of surveying.
