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...

Biografiska uppgifter:Hessel 1581-1632.
Gerritsz was apprenticed to W. J. Blaeu as an engraver before starting in business on his own account. He worked closely with Petrus Plancius and his merit may be judged by the fact that he was appointed Cartographer to the Dutch East India Company in preference to Blaeu and subsequently held the same position in a newly formed West India Company. With the new company he came into touch with Johannes de
Laet for whom he prepared a number of new maps of America in the latter's Nieuwe Wereldt published in 1625. His most important early work was a chart showing Henry Hudson's discoveries in his voyage of 1610-11: it is the first to give an outline of Hudson's Bay and indicates Hudson's belief that he had found a way to the North West Passage.
