Enceladus [SEP] discoverer or inventor
, tectonically deformed terrains.
Enceladus was discovered on August 28, 1789, by William Herschel, but little was known about it until the two Voyager spacecraft, "Voyager 1" and "Voyager 2", passed nearby in the early 1980s. In 2005, the "Cassini" spacecraft started multiple close flybys of Enceladus, revealing its surface and environment in greater detail. In particular, "Cassini" discovered water-rich plumes venting from the south polar region. Cryovolcanoes near the south pole shoot geyser-like jets
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.
