Johann Jakob Scheuchzer (born August 2nd 1672 - died June 23rd 1733). Swiss traveller naturalist and geologist. Contemporary Folio size Portrait copper engraving at 59 years old (1731) from Physica Sacra. His best known scientific works are his paleontological Lithographia Helvetica (1726) and his Physica Sacra, a massively scientifically illustrated Biblical History. In both books he states fossils as evidences of the Biblical flood. Notoriously he illustrated Homo Diluvii testis as a human victim of the flood. It was only identified correctly as a giant fossil salamander by Cuvier in 1811.
