Reinhold Tüxen

Reinhold Hermann Hans Tüxen (born 21 May 1899 in Ulsnis (Schleswig-Holstein); died 16 May 1980 in Rinteln) was a German botanist and plant sociologist. Along with Erich Oberdorfer, he was one of the early promoters and founders of modern plant sociology in Germany. His botanical author's abbreviation is Tüxen; in plant sociology, the abbreviation Tx. is also in use.

During the Third Reich Tüxen mapped the flora at Auschwitz for the plan of the SS model city of Auschwitz, as a pilot project for the integration of a conquered city. Here "German plants" were to form a border between the residential city and the extermination camp. However, in 1942 he was removed as chairman of the German working group for plant sociology due to a lack of Nazi Party membership and alleged political unreliability.
