John Hessler

John W. Hessler is a Fellow of the Royal Geographical Society, and the Curator of the Jay I. Kislak Collection of the Archaeology and History of the Early Americas at the Library of Congress in Washington, DC. He is the founder of The Topology Lab for Applied Computer Vision and Virtual Reality in Archaeology and is on the faculty of the Graduate School of Advanced Studies at Johns Hopkins University where he teaches classes in the Mathematical and Algorithmic Foundations of Computer Vision, and Virtual Reality Simulations. Hessler has given seminars on 3D imaging and the mathematics of computer vision around the world, including to the National Digital Stewardship Fellows in Washington, DC, and at the Kunsthistorisches Institut of the Max-Planck Institut in Florence. He has written extensively on the computational foundations of geographic information sciences and is the author over one-hundred articles and books including, The Naming of America: Martin Waldseemüller’s 1507 World Map and the Cosmographiae Introductio; A Renaissance Globemaker’s Toolbox: Johannes Schöner and the Revolution of Modern Science, 1475-1550; Thoreau on Cape Cod: his journeys and his lost maps; Seeing the World Anew: the radical vision of Martin Waldseemuller’s 1507 and 1516 World Maps; Galileo’s Starry Messenger; Columbus’ Book of Privileges, 1502: the Claiming of a New World and is the senior editor of MAP: Exploring the World, recently published by Phaidon. Much of his past research has concentrated on the use of computer vision and virtual reality in archaeological and geo-simulation and on the mathematical analysis of Roman, medieval and early Renaissance cartography, where he has developed new techniques for historical map geo-rectification and statistical shape analysis. His mathematical and computational studies of virtual and early mapmaking have been featured in numerous national media outlets including the New York Times, the Washington Post, Discover Magazine and most recently by NPR's All Things Considered. Currently, he is at work on a new translation and critical edition of Karl Friedrich Gauss' foundational work in differential geometry, Disquisitiones generales circa superficies curvas (General Investigations of Curved Surfaces), and a book of his collected lectures on computer vision entitled, Reconstructing Lost Worlds: Three-Dimensional Modeling, Computer Vision and Virtual Reality for Cultural Heritage Preservation (2018).
