Whose map first labeled America as a separate landmass?

German cartographer Martin Waldseemüller created a world map in 1507 that is the first known to apply the name America to the newly recognized western lands. He based the name on Amerigo Vespucci, whose accounts suggested the lands were not Asia but a separate continent. Waldseemüller's map was highly influential in the history of cartography. Later, the name America became standard for the continents. The map is a landmark in the history of geography and exploration.
