[4] He was the renowned leader of 24 Danish government expeditions to Greenland,[3] and the central character in the Lauge Koch Controversy, an international and intra-national conflict.
Beginning in December 1935 a bitter conflict arose between Koch and eleven of the most prominent Danish geologists of the day, including O.
Koch's observations of the interior of Independence Fjord led to considerable cartographic changes compared with the Peter Freuchen map of 1912.
[9] 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.
[11] 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.
