Johann Baptist Homann (1664-1724) was a pivotal German cartographer and publisher from Nuremberg who established one of Europe's most important mapmaking firms in the 18th century, known for detailed, scientifically rigorous, and aesthetically rich geographical and celestial maps, often featuring elaborate title cartouches, significant for ushering in German dominance in map production. His business, continued by his heirs (Homannische Erben) after his death, produced famous works like the Atlas Novus and Atlas Coelestis, making him a key figure in Enlightenment cartography.
