Pedro Reinel was a Portuguese cartographer. Between 1485 and 1519 Reinel served three Portuguese kings: João II, Manuel I and João III. He and his son, Jorge Reinel, were among the most renowned cartographers of their era, a period when European knowledge of geography and cartography were expanding rapidly. There is some evidence he was of African descent. Historian Rafael Moreira believes Reinel's father was an ivory carver brought from West Africa to serve in the royal workshops.
