Use in article (WP:NFCC#7) Karl Schröter
Purpose of use in article (WP:NFCC#8) For visual identification of the object of the article. The article as a whole is dedicated specifically to a discussion of this work.
Not replaceable with
free media because
(WP:NFCC#1)
Image is in black and white from the 1970's. Image is fuzzy, and poor. Low probability.
Minimal use (WP:NFCC#3) This is small black and white image, rather fuzzy of Karl Schröter. The image is small at 428 x 655 and is the minimal size available, with only half the picture showing the mathematician.
Respect for
commercial opportunities
(WP:NFCC#2)
Low probability as he was an obscure but important mathematician.
Other information The original image was docked, to only show Karl Schröter. It is a unique historical photograph of a mathematician who worked in the German Foreign office cipher bureau, Pers Z S. No other image is available, as I suspect he was averse to photography.
