1790-1825. Född i Verdalen, död i Trondheim.
Norsk officer. 1808 blev han officer, 1815 kapten och divisionsadjutant i Trondheim och 1823 major. Under åren 1810-14 utarbetade han en rad kartor över militära områden i Trondheims stift. Dessa kartor, som tidigare aldrig getts ut, ligger till grund för flera senare kartarbeten. Klüwer hade även starka arkeologiska intressen och lade ned ett betydande arbete vid utgrävning och registrering av fornminnen i sitt distrikt. Han var medlem av 'Det kgl. Norske Videnskapbers Selskab' i Trondheim och det svenska sällskapet Götiska förbundet.

Frisius, Gemma. [Reinerszoon, Jemme.]
9 december 1508 - 25 maj 1555.

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...
