Neumayr, Melchior (1845-90): passed his early life at Stuttgart, and entered the University of Munich in 1863 with the object of studying law, but he soon gave up legal studies for Geology and Palaeontology. In 1873 he was recalled from Heidelberg, where he held a post as Privatdocent, to occupy the newly created Chair of Palaeontology in Vienna. Dr. Neumayr was a successful and popular writer, as well as "one of the best and most scientific palaeontologists"; he was an enthusiastic supporter of Darwin's views, and he devoted himself "to tracing through the life of former times the same law of evolution as Darwin inferred from that of the existing world."
