German botanist (1779-1829).
Johann Baptist Ziz (8 October 1779–1 December 1829) was a German botanist, apothecary, and teacher of natural sciences at the Mainz gymnasium. He devoted himself to botanical studies, undertaking field trips across Germany and as far as southern France and the Pyrenees, and compiled a 170-page handwritten botanical notebook documenting the flora of Rheinhessen, the Rheingau, and the Lower Nahe, which remains a valuable primary source despite the destruction of his herbarium during the 1944 air raids on Darmstadt.
