Alexander Karpinsky
Alexander Petrovich Karpinsky was born in 1847, in Russia's Ural Mountains. The son and grandson of copper mining engineers, he spent his childhood in an area boasting a copper mine from the Bronze Age. The Urals provided Russians with a bounty of riches besides copper: gold, platinum, diamonds, sapphires, emeralds, amethysts, aquamarine, topaz, even chameleonlike alexandrite.
The Urals held other treasures, too, namely fossils.
