Environmental Geographer – Author ‘The Lost Sea of the Exodus’ A former surgeon, Fritz obtained a PhD in Environmental Geography as part of his quest to investigate the biblical exodus from Egypt. Realizing that the location of the miraculous sea crossing was not only a historical mystery, but the chief clue for the route to Mount Sinai, Fritz pursued the topic for his 2006 doctoral dissertation, entitled The Lost Sea of the Exodus. He has also published The Exodus Mysteries: of Midian, Sinai & Jabal al-Lawz (2019).
