52295 Köppen           Discovered 1990 Nov. 15 by E. W. Elst at the European Southern Observatory.
Wladimir Köppen (1846-1940) was a Russian-German botanist-climatologist. He developed the most popular system, still used, for a vegetation-based classification of the climate in different regions, a subdivision of climates into five major types, all but one defined by temperature criteria
