Paul Karl Wilhelm Scheerbart was a German author of speculative fiction literature and drawings. He was also published under the pseudonym Kuno Küfer and is best known for the book "Glasarchitektur" (1914). Scheerbart was associated with expressionist architecture and one of its leading proponents, Bruno Taut. He composed aphoristic poems about glass for the Taut's Glass Pavilion at the Werkbund Exhibition (1914). After writing in different publications he produced his first novel "Die große Revolution" ("The Great Revolution", 1902), which was published by the Insel-Verlag. The young Ernst Rowohlt published Scheerbart's bizarre poem collection "Katerpoesie" (1909) and became his friend.
