Hessel Gerritsz (1581-1632) was a noted Dutch mapmaker, engraver, and publisher who was also the official hydrographer of the Dutch East India Company. Gerritsz was born in Assum. His first exposure to mapmaking was as an apprentice to Willem Janszoon Blaeu, beginning in 1607. In 1610, Gerritsz began his own publishing business.
Gerritsz’s reputation grew quickly. In 1617, upon the recommendation of Petrus Plancius, Gerritsz was named as the cartographer to the Dutch East India Company (VOC). This meant that Gerritsz had access to the geographical information gathered by VOC navigators, but he could also still sell his own maps to the public. He reviewed the journals of the VOC, then prepared and corrected charts for their ships. In this post, Gerritsz created the first maps to include many new geographic features in the Indian and Pacific Oceans; these included some of the first European encounters with the coast of Australia.
