607 Jenny [SEP] discoverer or inventor
607 Jenny
607 Jenny is a minor planet orbiting the Sun that was discovered by German astronomer August Kopff on September 18, 1906.
Photometric observations of this asteroid at Palmer Divide Observatory in Colorado Springs, Colorado during 2007 gave a light curve with a period of 8.524 ± 0.005 hours and a brightness variation of 0.21 ± 0.03 in magnitude. Results reported in 2003 giving a period of 7.344 hours were deemed the result of a data ambiguity.

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.
