'''Lauge Koch''' (5 July 1892 – 5 June 1964) was a Danish geologist and Arctic explorer.
==Biography== Lauge Koch was born in 1892 to Karl and Elisabeth Koch. His development as a scientist was greatly influenced by his father's second cousin Johan Peter Koch - a polar explorer, a member of several Greenland expeditions, including Ludvig Mylius-Erichsen's and Alfred Wegener's (in the latter's expedition (1912-1913) to cross Greenland, he led a sledging party).{{sfn|Hansen|2012|p=1104}} He received his higher education at the University of Copenhagen, where he began his studies in 1911, in 1920 he received a master's degree,<ref name="EA">{{cite encyclopedia|url=https://collections.dartmouth.edu/arctica-beta/html/EA15-42.html|title=Lauge Koch|author=Hobbs W.

Beginning in December 1935 a bitter conflict arose between Koch and eleven of the most prominent Danish geologists of the day, including O. B. Bøggild, director of The Mineralogical Museum and professor at the Geological Institute of Copenhagen University, and {{Interlanguage link multi|Victor Madsen|2=sv|3=Victor Madsen (geolog)|preserve=1}}, head of the Geological Survey of Denmark.
Controversy started with a review of the Lauge Koch book ''Geologie von Grönland'' (1935) written by ‘the eleven’ and accusing Koch of poor and improper scientific practice.<ref Name="Ries">{{cite web|last=Christopher Jacob Ries, Roskilde University|title=The Lauge Koch Controversy: International Cooperation and intra-national conflict in Danish arctic research 1930-1940|work=Ideologies and Controversies in 20th Century Scientific Exploration|publisher=Steno Institute|year=2007|url=http://www.si.au.dk/arrangementer/kolf07/210507|format=web|access-date=2008-01-05|url-status=dead|archive-url=https://archive.today/20070610165038/http://www.si.au.dk/arrangementer/kolf07/210507|archive-date=2007-06-10}}</ref><ref Name="Bravo">{{cite book|author1=Michael Bravo|author2=Sverker Sörlin|title=Narrating the Arctic: A Cultural History of Nordic Scientific|publisher=Science History Publications/USA|year=2002|pages=197|url=https://books.google.com/books?id=6wjlteumklQC&q=%22lauge+koch%22|isbn=0-88135-385-X}}</ref> Relating to the years 1921–23 in which Lauge Koch conducted the Bicentenary Jubilee Expedition to North Greenland in the year of the bicentennial jubilee of Hans Egede's landing in Greenland, Koch made a sledge journey along the north coast of Greenland, round Peary Land and back across the Inland Ice. On this journey Koch discovered a depression which in his opinion was the one that Robert Peary in 1892 had mistaken for a channel —the so-called "Peary Channel". Koch's observations of the interior of Independence Fjord led to considerable cartographic changes compared with the Peter Freuchen map of 1912.<ref>[http://www2.kb.dk/kb/dept/nbo/kob/danmarkskort/eng.jubie.htm The Bi-centennary (sic) Jubilee Expedition 1920-23] at eng.jubie</ref>
In 1922 he mapped Hiawatha Glacier, and noted that the glacier tongue extended into Lake Alida (near Foulk Fjord).<ref>{{cite web|url=http://hydrologie.org/redbooks/a058/05813.pdf|title=The recent regimen of the ice cap margin in North Greenland|last1=Davies|first1=William E.|last2=Krinsley|first2=Daniel B.|publisher=International Association of Scientific Hydrology, Commission of Snow and Ice|year=1962|page=124|access-date=2018-11-16|archive-date=2021-06-25|archive-url=https://web.archive.org/web/20210625040947/http://hydrologie.org/redbooks/a058/05813.pdf|url-status=dead}}</ref>
In 1938, Lauge Koch found in the mountains west of Jameson Land, near Scoresby Sound, the skeleton of a huge extinct mammal similar to the head of a gigantic animal with huge teeth found by Professor Selim Hassan in 1935 near the pyramid of Chephren. The skeleton found by Koch was displayed at the museum in Copenhagen.<ref Name="Wilkins">{{cite book|last=Wilkins|first=Harold T.|title=Secret Cities of Old South America|publisher=Adventures Unlimited Press|year=1998|pages=326|url=https://books.google.com/books?id=hkRHSzwIU2oC&q=1935+%22lauge+koch%22&pg=PA326|isbn=0-932813-55-0}}</ref>
Amongst his other contributions to the sciences, in the mid-1930s Koch established a network of field stations and traveling huts in Central East Greenland. This establishment of a permanent infrastructure in the field caused a change in the whole culture and organization of Danish Arctic exploration.<ref>{{cite web|last=Christopher J.

His last expedition was the 1956-58 Expedition to East Greenland in which he used helicopters. But the Danish government cut funding in mid-expedition and Koch's career as expedition leader was terminated.<ref>[https://www.erudit.org/revue/scientia/2010/v33/n2/1006149ar.pdf Matthias Heymann, Henrik Knudsen, Maiken L.

==Legacy== The mineral kochite which is found in Mt Hvide Ryg, Werner Bjerge, and the former Greenland county of Tunu was named for Koch in honor of his explorations in the same areas.<ref>[https://webmineral.com/data/Kochite.shtml Kochite Mineral Data]</ref><ref>[http://www.mindat.org/min-25598.html Kochite]</ref><ref>[http://www.mindat.org/locentry-194984.html Kochite from Mt Hvide Ryg (north slope), Werner Bjerge, Tunu (East Greenland) Province, Greenland]</ref>
The coelacanth ''Laugia'' from the Early Triassic of Greenland is named in his honor.
