Franz Eugen Geinitz (15 February 1854, Dresden – 9 March 1925, Rostock) was a German geologist and mineralogist best known for his geological studies of the Mecklenburg region. He was the son of geologist Hanns Bruno Geinitz.

Biography

In 1876 he obtained his PhD from the University of Leipzig with a dissertation on mineral pseudomorphs. During the following year he received his habilitation from the University of Göttingen, and shortly afterwards, became an associate professor of geology and mineralogy at the University of Rostock. In 1881 he became a full professor and director of the mineralogical-geological institute at Rostock. In 1903/04 he served as
