[Eugene Alvin Villar]

http://en.wikipedia.org/wiki/Gerardus_Mercator

Gerardus Mercator was born on March 5, 1512 in Rupelmonde in what is
now Belgium.

He is primarily known as the cartographer who invented the Mercator
projection, of which the spherical variant is used by various online
map websites like Google Maps, Bing Maps, Yahoo Maps, and of course,
OpenStreetMap.

In addition, Merkaartor, one of the main OSM editors is also named after him.
