Hello! You have found the address? Is this correct?
Are the photos in the link that you sent me the current building where the bookstore used to be?

I'm sorry I don't speak German - only English!

Gerhard Simon was the youngest brother of my maternal grandmother. Gerhard was born and raised in Gottingen. He died in Russia during World War II - we don't know what happened to him. But ... he was married (I think his wife was Marianne) and he had a child. I want to find a connection to these people!
