Passage Saulnier has been changed into Rue S. in 1902. Have a look here:
Volker Dehs, Eisenbahnstr. 9, D-37073 Göttingen.

Betreff: 18 Passage Saulnier
When Jules Verne celebrated his first success as a novelist he was occupying a flat at 18 Passage Saulnier (V.Dehs, Jules Verne. Biographie, 2005, page 117. W.Butcher, Jules Verne. The Definitive Biography, revised 2008, page 334).
There is no such street in Paris at present. What about Rue Saulnier which can be found on Google Maps? Is this the new name for the old passage or is it located elsewhere?
Does any member of the forum know?
