The German Archaeological Institute was established in Berlin in AD 1832 and is directed by the Foreign Office of Germany with offices around the world in Athens, Baghdad, Cairo, Damascus, Istanbul, Madrid, Rome, Tehran, and Sana'a.
Dr. Reinder Neef, on staff who has an extensive seed collection of both green and carbonized seeds that he can use to identify plant materials from Archaeological sites. Then he can use that information to identify what they were eating and also study trade between different production areas.
