Othmar Ammann, Ammann Family, Schaffhausen, Switzerland, Genealogy
The story of the Ammann family of Schaffhausen sketches a cross section of the history of that town from the middle of the 15th century into the end of the 20th. Likewise, the events of history as they played out in Schaffhausen during those times very much shaped the history of the Ammann family.
