Nikolaj Hartz

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]

Biography

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]

Personal life

In 1901, he married Anna Berg. Their son was the painter Lauritz Hartz (1903-1987).[6]

Legacy

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]

gollark: I prefer base 16.
gollark: We had that idea yesterday. Keep up.
gollark: It uses some incredibly bizarre mix of bad OOP and just plain imperative programming a lot.
gollark: So actually lots of them are sensible but some of them are just really bad.
gollark: `collections` is okayish maybe, right?
