Gerardus Mercator
5 March 1512 — 2 December 1594
Gerardus Mercator was a Flemish geographer, cosmographer and cartographer. He is most renowned for creating the 1569 world map based on a new projection which represented sailing courses of constant bearing as straight lines—an innovation that is still employed in nautical charts.
