Karl Stoerk

Afterwards he was an assistant to Ludwig Türck (1810–1868) in Vienna, where he practiced medicine for the remainder of his career.

Along with Leopold von Schrötter (1837–1908) and Johann Schnitzler (1835–1893), Stoerk was a catalyst in making Vienna a major center of laryngological research in the late 19th century.

He demonstrated the possibility of applying remedies into the larynx and throat assisted by a laryngoscope.

Stoerk's endoscopic device consisted of three telescopic tubes with a bendable mechanism.

"Stoerk's blennorrhea": free discharge of mucus producing hypertrophy of the mucosa of the nose, pharynx, and larynx.
