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...

Sista levnadsåret guvernör på S:t Barthelemy. Gift med Kristina Sofia Apelqvist, avliden ej långt efter maken i Gustavia på S:t Barthelemy. Deras son Johan Henrik föddes på S:t Barthelemy 13 oktober 1813. Han återfördes till Sverige av släktingar och genomgick en framgångsrik karriär, rikt dekorerad med utmärkelser, och var krigsminister då St Barthelemy återfördes till Frankrike.

B. Smolenskoye, Vereysky district [now Moscow region], 1716-18; d. St Petersburg, 25 Feb 1770.
Russian draughtsman and engraver. He was the son of a priest, and from 1729 he studied at the St Petersburg Naval Academy. In August 1731 he was transferred to the instrument-making department of the Academy of Sciences, where he helped to make land-surveying instruments, including theodolites (a training that was of value when he later came to sketch views of St Petersburg); he also learnt how to carve moulds for dies under Georg Unfertsagt (1701-67); and he studied drawing under the two members of the Academy staff, Ottmar Elliger II and Elias Grimmel (1703-58). In June 1743 Makhayev was made director of the cartographic and die-carving section of the Academy, and he was employed there for the rest of his life. Together with his pupils he helped to produce the Atlas rossiyskoy imperii ('Atlas of the Russian Empire'; 1740s); in addition, he provided inscriptions for diplomas for honorary members of the Academy, for porcelain snuff-boxes and for a large silver shrine at the tomb of Aleksandr Nevsky (early 175...

GERRITSZ [GERARD, GERARDUS, GHERRITSZOON van ASSUM].
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.
Engraver, cartographer, publisher and bookseller, b. Assum, apprenticed as engraver to Blaeu, Cartographer to Dutch E. India Co. 1617, fl. 1607; from 1612 using sign 'in de Paskaert' or 'sub signo Tabulae Nauticae'.
