Johannes Greenland

Johannes Grönland , also Groenland, in France also Jean Groenland, (born April 8, 1824 in Altona , † February 13, 1891 in Dahme / Mark ) was a German botanist ( bryologist , lichenologist ), gardener and microscopist. Its official botanical author's abbreviation is " Groenland ".

Life

Greenland was the son of an organist and music teacher and trained as a pharmacist in Altona, where Karl Moritz Gottsche introduced him to bryology. Later he worked in a pharmacy in Jena, where he also heard Matthias Jacob Schleiden's lectures on botany. In 1849 he fought against Denmark in the Schleswig-Holstein uprising . After the peace treaty he stayed as a pharmacist in Schleswig-Holstein until 1853 and also studied the local flora and published about Zostera marina . He then went to Paris as an assistant to the gardener Louis de Vilmorin . For this he later published a German edition of the gardener's manual with Theodor Rümpler . He was sponsored by the botanist Jacques Étienne Gay and introduced into the botanical circles in Paris. Greenland lived in Paris as a botanist for almost twenty years. He was an employee of the Revue horticole and a founding member of the French botanical society and was known for breeding experiments, particularly of hybrids of aegilops and wheat, to clarify the then current research question of the origin of wheat. He carried out the experiments with the Vilmorins and later at the Jardin des Plantes . He published microscopic botanical preparations for the trade and, with colleagues, wrote a textbook about their preparation, which at the time was a standard work in microscopy. In the Franco-Prussian War he left France in 1871 (during the siege of Paris he had to endure in the city with his wife) and moved to Dahme, where he was a professor at the agricultural college and at the agricultural chemical research station for 19 years.

He did research especially on liverworts , sea ​​grasses and sundew (whose glands he examined microscopically). After returning to Germany, Greenland was active in the Botanical Association of the Province of Brandenburg. In 1858 he became a member of the Leopoldina .

Honors
