Professor Dr. Werner Rodolfo Greuter, (born February 27, 1938) in Genova, Italy, as a Swiss national, is a prominent botanist. He is well known as the chair of the Editorial Committee for the International Code of Botanical Nomenclature (ICBN) - both the previous St Louis Code (2000), and Tokyo Code (1994), but not the current Vienna Code (2006). His proposed policy as regards registration of botanical names proved unpopular and in 1999 he stepped back, not being elected anew: he merely completed his term as chair to be succeeded at Vienna in 2005.
He was appointed on April 1, 1978 to his current position: Professor of biology in the Institute of Biology at the Free University of Berlin, Germany, and First Director of the University's Botanic Garden and Botanical Museum (BGBM) in Berlin.
