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...

Fransk kartograf, son till ROBERT DE VAUGONDY, GILLES. Han verkar ha gått i sin fars fotspår som kunglig geograf och hade dessutom titeln 'censeur royal'. Förutom nyutgåvor av faderns olika atlaser gav han 1785 ut 'Atlas de la France et de l'Europe'. Robert de Vaugondys atlas blev senare reviderad och utgiven på nytt av C. F. Delamarche.
