"Gerd Weisgerber (January 24, 1938, Saarwellingen – June 22, 2010, Recklinghausen) was an eminent German professor of mining archaeology. He was one of the first mining archaeologists of the world, who set standards in this scientific discipline. As a scientist from the German Mining Museum, he focused his research mainly on Western Asia, especially on Oman, Jordan, Palestine, and Iran." - (en.wikipedia.org 11.04.2022)
