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...

Holländsk kartgravör. Inga övriga upplysningar hittade.
Holländsk bok- och karthandlare i början av 1700-talet. 1721 ingick han kompanjonskap med Cornelius Mortier (se denne) och fortsatte under firmanamnet Cóvens et Mortier Pieter Mortiers (se denne) affär i Amsterdam. Firman gav ut flera stora atlaser, i de flesta fallen sammansatta med kartor utförda av flera kartritare under en relativt lång tid. Förutom ett par odaterade verk kan nämnas 'Nouvel Atlas' (ca. 1735) och 'Nieuve Atlas' (1730-39). 1761 kom 'Atlas nouveau' med kartor så långt bak i tiden som 1683. Firman fanns kvar till 1817.
