Johann Baptist von Spix, German biologist and explorer (d. 1826)
Johann Baptist Ritter von Spix (9 February 1781 – 13 March 1826) was a German biologist. From his expedition to Brazil he brought to Germany a large variety of specimens of plants, insects, mammals, birds, amphibians and fish. They constitute an important basis for today's National Zoological Collection in Munich. Numerous examples of his ethnographic collections, such as dance masks and the like, are now part of the collection of the Museum of Ethnography in Munich.
