Sondergotik [SEP] discoverer or inventor
Sondergotik
Sondergotik (Special Gothic) is the style of Late Gothic architecture prevalent in Austria, Bavaria, Saxony and Bohemia between 1350 and 1550. The term was invented by art historian Kurt Gerstenberg in his 1913 work "Deutsche Sondergotik", in which he argued that the Late Gothic had a special expression in Germany (especially the South and the Rhineland) marked by the use of the hall church or "Hallenkirche". At the same time the style forms part of the International Gothic style in its origins.

Fritz Klatte
Fritz Klatte (28 March 1880, Diepholz – 11 February 1934) was a German chemist and the discoverer of polyvinyl acetate, with German patent (GP 281687 1912) for its preparation from acetylene gas.
Polyvinyl chloride (PVC) was discovered by French physicist Henri Victor Regnault, and German physicist Eugen Baumann. Klatte designed the production process, although never successfully commercialised it. Klatte is sometimes incorrectly attributed to be the discoverer or inventor of PVC.
