Who started a school for navigators helping to advance map making by using the printing press

Prince Henry the Navigator

Explanation:

Prince Henry the Navigator, a Portuguese prince, started school to teach the sailors about the Oceanic exploration at Sagres, Portugal around 1418. In this school, sailors trained by studying science, navigation, and map-making, to sail in unknown places. Prince Henry the Navigator is known for his supporting the exploration along the west coast of Africa. Because of Henry patronage, sailors were able to establish colonies outside Europe. With the enthusiasm of conducting voyage for exploration, Portuguese established trade with India, Africa, and Orient for spices, gold, porcelain, and silk.

after defeating german forces in north africa allied leaders turned their attention to "italy," since this was the location that made the most geographic sense before invading northern europe via france.
