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...

CÓVENS, JOHANNES.

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.

L'ENFANT, PIERRE CHARLES.

Biografiska uppgifter:1754-1825.
L'Enfant was born in Paris where he trained to be an architect. He came to America in 1777, and served George Washington as an engineer during the Revolutionary War. In 1791 President Washington asked L'Enfant to design the new capitol city in the District of Columbia. L'Enfant designed a city similar in layout to the then French capitol city of Versailles. The Capitol in Washington sits in a position similar to that of the palace in Versailles, the White House (originally called the President's House) in the position of Grand Trianon, and the Mall is like the Parc. The Commissioners of the City of Washington wanted to have a printed copy of the plan when they began to sell building lots. L'Enfant irritated them by working slowly and releasing only sketchy plans . On instruction from President Washington, Thomas Jefferson on February 27, 1792 wrote a letter to L'Enfant dismissing him as city planner. L'Enfant died penniless and was buried on a friend's estate. In 1909 his remains were moved to Arlington National Cemetery on a hill overlooking the capitol city.
