General Sir Albert Houtum-Schindler (1846-1916) was a scholar of Persia and an employee of he Persian government. He was heavily involved with the turquoise mines of Nishapur Khorassan (present day Iran). The turquoise mines were the principal turquoise deposits in the world at this time. Until the publication of Schindler’s report very little was known about them. Since 1882 the mines had been in the hands of a Persian company which held a concession from the Shah for fifteen years and Schindler was the manager until 1883. He describes the mines, veins and provides details on the three grades of turquoise acquired from the veins.
