If Professor Pleischner from the popular Russian TV show about Soviet intelligence activities in Nazi Germany, Seventeen Moments of Spring (1973), had really been in Bern during the 1940s, he would not have found Blumenstrasse because such street never existed in the Swiss capital. If this story had taken place today, Professor Pleischner would have rather been very surprised to find Tumarkinweg, a street named after a Russian woman, Anna Tumarkin. Who is Anna Tumarkin, and why is Switzerland so proud of her?
