In the second decade of the 20th Century, first under the influence of his friend Ernst Gosebruch, the director of the Essen Museum of Art, Hagemann turned toward painters of Die Brücke and Emil Nolde.
Hagemann's ester, or ethyl-2-methyl-4-oxo-2-cyclohexenecarboxylate, is an organic compound that was first prepared and described in 1893 by German chemist Carl Hagemann.
