Wilhelm Ostwald, 1853 (Riga, Latvia) – 1932 (Leipzig, Germany) was one of the founders and the organizer of the discipline ‘physical chemistry’ at the end of the 19th century. He worked from 1887 until 1906 as professor in Leipzig, received the 1909 Nobel Prize in chemistry for his work on catalysis, equilibria and rates of chemical reactions.
Especially after his retirement he developed broad and multifaceted interests as well as wrote numerous publications in philosophy (of nature), history (of science) as well as color theory and the international organization of scholarly work e.g. through promoting an artificial language.
