Tatiana Warsher (Moscow 1880 - Rome 1960), a pupil of Michael Rostovtzeff at the University of St. Petersburg, published the guidebook Pompeji, ein F├╝hrer durch die Ruinen in 1925, also translated into other languages. She compiled huge manuscript volumes on Pompeii, including photographs, maps and plans.
