Jean-Jacques de Morgan (3 June 1857 – 14 June 1924) was a French mining engineer, geologist, and archaeologist. He was the director of antiquities in Egypt during the 19th century, and excavated in Memphis and Dashur, providing many drawings of many Egyptian pyramids. He also worked at Stonehenge, and Persepolis, and many other sites. He also went to Russian Armenia, as manager of a copper mine at Akhtala. "The Caucasus is of special interest in the study of the origins of metals; it is the easternmost point from which prehistoric remains are known; older than Europe and Greece, it still retains the traces of those civilizations that were the cradle of our own." In 1887-89 he unearthed 576 graves around Alaverdi and Akhatala, near the Tiflis-Alexandropol railway line. Source: Wikipedia (en)
