This really is not about the photographer, it is much more about the photograph, and much more about the people in the photo and what became of them.
I found it fascinating on a few levels.
Regards The War To End All Wars .......
As an after-thought...i do not know if there is a sadder, or is it more sad, story about a photographer. He seemed very capable and somewhat prolific for his time and equipment available.
I am not sure there was ever a city, not in recent times anyway, that went through the (Horrible) metamorphosis that Berlin did. It went from The Mecca of art and entertainment to one of the most restricted of a "Modern Society"
I would imagine there were Thousands of people like Sander. Not just the Artists/Entertainers themselves, but all the people that participated as patrons and the owners of venues and all other sorts that catered to those times.
Thanks for this most rewarding post. Learning the details of these young men's lives fleshed out the actuality in this small piece of what has become a canon. I had once became acquainted with Sander's daughter, herself a talented potter. It is striking and enriching to suddenly be faced with the personal humanity of an 'iconic' photo.
