Nikolaj Eeg Kruse Hartz (23 August 1867 – 7 May 1937) was a Danish geologist and botanist. He was an important explorer of the flora of Greenland during several expeditions. [1]
Hartz was born in Randers, Denmark. He studied botany at the University of Copenhagen. In 1891-1892 he participated in the expedition to Scoresbysund and Tasiilaq led by Carl Ryder (1858-1923). He graduated in 1895 and obtained a Ph.D. in 1909 with a dissertation about the late-glacial flora and fauna of Denmark. From 1896, Hartz was a researcher at the Geological Survey of Denmark. In 1900 he participated in the Carlsbergfund Expedition to East Greenland under the leadership of G. C. Amdrup (1866-1947). He investigated plant and animal remains in deposits from before, during and after the last glaciation. Together with his colleague Vilhelm Milthers (1865–1962), he investigated a clay pit near Allerød in Denmark and found that a period with milder climate and birch forest – the Allerød oscillation - had interrupted the cold and dry Dryas stadial (Hartz & Milthers 1901). [2] [3] [4]
In 1913, he abandoned his scientific career and became co-director of his brother's firm, Standard Mønsterforretning which had been established in Kristiania, Norway in 1900. [5]
In 1901, he married Anna Berg. Their son was the painter Lauritz Hartz (1903-1987). [6]
The grass species Poa hartzii was described by the French botanist Michel Gandoger (1920), who named it after Hartz because it was based on plants collected by Hartz in "Kordlunguak" at the Sullorsuaq Strait, West Greenland. [7] [8]
Rudkøbing is a town in Denmark, on the western coast of the island of Langeland. It is the seat of Langeland Municipality, in the Southern Denmark Region. The town is located 15 kilometres (9.3 mi) southeast of Svendborg and is connected to Siø through the Siøsund Bridge.
The Bølling–Allerød interstadial, also called the Late Glacial Interstadial, was an abrupt warm and moist interstadial period that occurred during the final stages of the Last Glacial Period. This warm period ran from 14,690 to 12,890 years before the present (BP). It began with the end of the cold period known as the Oldest Dryas, and ended abruptly with the onset of the Younger Dryas, a cold period that reduced temperatures back to near-glacial levels within a decade.

Jens Wilhelm August Lind was a Danish apothecary, botanist and mycologist. He was a pupil of Emil Rostrup and published a full account of all fungi collected in Denmark by Rostrup. These were mainly microfungi, such as plant pathogens. He also wrote accounts on microfungi from Greenland and elsewhere, mainly based on collections made by other persons on expeditions, e.g. Gjøa expedition and the Second Thule Expedition. Combining his pharmaceutical and mycological knowledge, he was early in experimenting on chemical control of plant pathogens and recommending it to other practitioners. He also - together with Knud Jessen - wrote an account on the immigration history of weeds to Denmark.
