MERCATOR, GERARD (Gerard de Cremere el. Kremer).
5/3 1512- 2/12 1594. Född i Rupelmonde i Flandern, död i Duisburg.
Belgisk-tysk geograf. Från 1530 studerade han vid universitetet i Leuven under astronomen och kartografen Gemma-Frisius (se denne), och var dennes assistent under arbetet med hans jordglob. Hans första självständiga arbete, en Palestinakarta från 1537, finns det idag bara en känd kopia av. Lika sällsynta är flera av hans andra tidigaste arbeten. År 1541 konstruerade han en jordglob över jordklotet och en himmelsglob, båda på uppdrag av kejsare Karl V. År 1552 slog han sig ned i Duisburg där han sedan fortsatte sin verksamhet. 1569 gav han ut en liten bok om kronologi och samma år kom hans framstående världskarta. 1578 gav han ut Ptolemaeus geografi, kompletterad med sina egna kartor. Detta verk kom i 7 nyutgåvor, den senaste 1794. Mercator är ansedd som den mest betydelsefulla geografen sedan Ptolemaeus. Hans främsta verk, 'Atlas, sive cosmographicae meditationes de fabrica mundi' utkom första gången 1585 och slutfördes 1595, en kort tid efter hans död. Detta arbete var epokavgörande och kom fram till 1642 ut...

Became instructor at the pilot school of Karlskrona in 1745. In an official communication pointing out the inadequacy of Swedish sea charts, Wallman called for more astronomical observations and more careful measurements. Appointed commander and director of pilots in 1755, he was handed the opportunity of personally directing marine measurements, principally on the southern coastline. A successor summed up Wallman's career: 'Nobody before or after has made such great personal contribution to the sounding of our coasts'

Knight Leontiy Vassilievich Spafaryev (1765 - 30 January 1847) was a Lieutenant General of the Imperial Russian Navy. Spafaryev was Director of the Lighthouse Administration and cartographer of the Russian Admiralty.
Spafariev was an important contributor to the improvement of navigation along the Russian coasts. The first lighthouses in Russia were built during tsar Peter the Great's drive for reform and modernization at the beginning of the 18th century. However, it was only until the Administration of Lighthouses was created in 1807 that the Russian lighthouse system followed an organized pattern, becoming effective and efficient. This office was established by the Russian Navy and it began under the leadership of Leontiy V. Spafaryev.
As a cartographer, perhaps his most outstanding work is the 'Atlas of the Gulf of Finland', published in 1817. His name is spelt as 'Spafarief' or 'Spafarieff' in the United States.
The Spafaryev Islands in the Sea of Okhotsk and Spafarief Bay in the coast of Alaska were named after Leontiy V. Spafaryev.
