Gemma Frisius
08.12.1508 - 25.05.1555
Gemma Frisius, born Jemme Reinerszoon Frisius, was a Dutch mathematician, physician, cartographer, philosopher, engraver, and master of astronomical instruments.
He taught mathematics and medicine at the University of Leuven and applied his mathematical knowledge to astronomy, geography, and map-making. Frisius participated in the creation of the latest globes and used mathematics in geodesy and navigation in new ways and invented or improved many instruments, including the cross staff, the astrolabe, and the astronomical rings (also known as "Gemma rings"). He ran a workshop for making such instruments.
Frisius is credited with being one of the founders of the Dutch school of cartography.
