Schwartze Sign

Excerpt

The Schwartze sign is named after the German otologist Hermann Schwartze (1837-1910), who, in his day, was the first otologic professor in Germany. His work focussed on different otologic diseases, one of which being the ankylosis of the stapes now known as otosclerosis, a name defined several years later by Adam Politzer. Modern literature credit Hermann Schwartze with the discovery of a characteristic coloration of the promontory related to otosclerosis, but it remains unclear whether he used the term himself.
