Welcome to season four! To kick it off, we go to the not so distant past to a remarkable archeological find in Bosnia in 2019--a (probably) 14th century sword in the stone! From there, we travel back further into history to meet the inventor of the one of the most disruptive pieces of technology in at the turn of the 20th century--the diesel engine, created by Rudolf Diesel. While crossing the English Channel on an overnight ferry, Diesel disappeared. Was it suicide? Murder? Was the body found (yet not recovered) even his? The questions that swirled around the mysterious circumstances of his disappearance also fueled conspiracy theories that put two of the world's most powerful men as the culprits for his murder--John D. Rockefeller and Germany's Emperor Kaiser Wilhelm II. *~*~*~*~*~ The Socials and Patreon!
