This list of over 1'300 CdV photographers who were active in Switzerland between 1860 and 1925, is not yet complete. It is based on my collection. Some CdVs of photographers are harder to find because they were probably only briefly active and many CdVs of them have been already lost. Most were studio photographers, some of them were specialized in landscape photography or just had a branch in Switzerland.
