Sergey Prokudin-Gorsky was a Russian photographer, he took and developed some of the first color photographs. Aside from this technical achievement, they show our world today what the Russian Empire was like at the turn of the century--rural, barely industrialized, filled with many different peoples, cities and cultures that can't be found in much of Europe or Asia anymore.

It is interesting to see a country like Russia before World War I, socialism, World War II, electrification, and global capitalism. I thought you robots would enjoy this.
