Wladimir Koppen

Vladimir Peter Köppen (Russian: Влади́мир Петро́вич Кёппен, Vladimir Petrovich Kyoppen) (September 25, 1846 – June 22, 1940) was a German geographer, meteorologist, climatologist and botanist. After studies in St. Petersburg, he spent the bulk of his life and professional career in Germany and Austria. His most notable contribution to science was the development of the Köppen climate classification system, which, with some modifications, is still commonly used.
