Frisius, Gemma. [Reinerszoon, Jemme.]
9 december 1508 - 25 maj 1555.
Gemma Frisius was a physician, mathematician, cartographer, philosopher, and instrument maker. He created important globes, improved the mathematical instruments of his day and applied mathematics in new ways to surveying and navigation.
Frisius was born in Dokkum, Friesland (present-day Netherlands) of poor parents, who died when he was young. He moved to Groningen and studied at the University in Leuven beginning in 1525. He received the degree of MD in 1536 and remained on the faculty of medicine in Leuven for the rest of his life. His oldest son, Cornelius Gemma, edited a posthumous volume of his work and continued to work with Ptolemaic astrological models.
While still a student, Frisius set up a workshop to produce globes and mathematical instruments. He became noted for the quality and accuracy of his instruments, which were praised by Tycho Brahe, among others. In 1533, he described for the first time the method of triangulation still used today in surveying. Twenty years later, he was the first...

Petrus Bertius grew up in Beveren in Flanders and as a young man travelled widely in Europe. In company with so many of his compatriots he moved to Amsterdam as a refugee from religious persecution and after completing his studies there he was appointed a professor of mathematics and librarian at Leyden University. As well as being a prolific writer on mathematical, historical and theological subjects he is known as a cartographer for his editions of Ptolemy's Geographia (based on Mercator's edition of 1578) and for the miniature atlases detailed below. In 1618 he moved to Paris and became Official Cosmographer to Louis XIII. He was related by marriage to Jodocus Hondius and Pieter van den Keere.

Engelsk kopparstickare och geograf. Han graverade en mängd illustrationer för böcker och tidskrifter, och utförde även kartarbeten för geografiska verk. 1773 gav han ut en 'General Atlas' som till 1804 utkom i 12 utgåvor. Ett annat verk, 'New universal Atlas' kom till 1805 i 7 utgåvor. 1778 gav han ut 'Royal English Atlas' som även innehöll arbeten av andra kartografer. På en karta från 1775 betecknar han sig som 'Hydrographer to His Majesty'.
