The Duisburg Museum of Cultural and City History houses a valuable collection of works by the great cartographer and polymath Gerhard Mercator (1512-1594), who lived in Duisburg for over 40 years. He created the first atlas of the world, developed the Mercator projection - the basis of exact navigation to this day - and also worked as an engraver, globe and instrument maker in his workshop in Oberstraße.
Highlights of the "treasure trove" are certainly the well-preserved pair of terrestrial and celestial globes, the first "atlas" of the world from 1595, the digital world map and the Duisburg map by Mercator's pupil Johannes Corputius from 1566.
