Wilhelm Pischner designed Neuzeit Grotesk for Stempel AG in the late thirties.
Part of a self-initiated research, I've been looking for a portrait photography of him without any success so far.
I've asked Linotype, the Klingspor Museum and the Hessisches Landesmuseum in Darmstadt. Any of these institutions has seen a picture of this designer. Before enquiring at Offenbach's city archives, where he was born, I decided to post on this forum.
Thanks in advance for your help.
