Throughout 1936 and 1937, Kirchner began to experience health problems and was prescribed Ovaltine and Eukodal by his doctors. In 1937, the Degenerate Art Exhibition took place in Germany; a total of 639 works by Kirchner were taken out of museums and 25 were displayed in the exhibition. The Academy of Arts in Berlin expelled Kirchner as a member. Kirchner continued to work and organised a major exhibit in Basle, which received mixed reviews.
