Street names as a base for a history book

Lingua Franca - 21/01/2006: Does The World Need Esperanto?

Reading the above article on Esperanto reminded me of Ludwig Zamenhof street, near our blocks of flats in Bulgaria. This lead to the idea that since people had a reason to call a street what it is, it may be interesting to share it with others. Hence, imagine a book or a tourist tour around this notion.
