Chet Van Duzer is a widely published historian who specialises in historic maps, with an emphasis on determining the sources that cartographers used for the texts, images, and geographical features in their works. One part of his work has been recovering information from damaged maps using multispectral imaging. He was the 2012 Kislak Fellow at the Library of Congress and is a Board Member of the Lazarus Project at the University of Rochester, which provides low-cost access to multispectral imaging to institutions and researchers around the world. Chet’s book Sea Monsters on Medieval and Renaissance Maps was published by the British Library in 2013.
