Nils Johannsson
Nils Thuresson Johannsson (born August 12, 1893 in Klara parish near Stockholm , † March 18, 1939 in Bromma parish near Stockholm) was a Swedish paleobotanist and botanist.
Johannsson studied at Stockholm University from 1913 to 1917 and was then a teacher in Stockholm until 1935. From 1919 to 1921 he was involved in the investigation of peat deposits for the geological survey of Sweden and from 1920/21 he worked in the palaeobotany department in the Reichsmuseum. He received his doctorate in 1927 and then went on a research trip to Central America and the Caribbean. In 1929 he became a professor of plant physiology at the Forestry School.
At first he dealt with the flora of the Triassic in various coal deposits in Sweden, later with plant physiology, especially with experiments on the respiration of plants. From 1937 he got a new edition of the botany textbook for high schools of his teacher JAO Skärman.
