Sergei Mikhailovich Prokudin-Gorskii

I've always been fascinated by the work of Gorskii and his photography process. Remember, these are not black-and-white photographs that have been colorized, but rather they're original color pictures arrived at by "Digichromatograpghy" which you can read more about right here.

Here we see a group of young, Jewish children with their teacher in Russia. Keep in mind that this picture was taken...in 1914! (Click picture to enlarge.)
