History of otorhinolaryngology in Germany before 1921.

In 2021, the German Society of Otorhinolaryngology, Head and Neck Surgery is celebrating the 100th anniversary of its foundation. The aim of this article is to present the main inventions and progress made in Germany before 1921, the date the society was founded. Three chronological periods are discernible: the history of otorhinolaryngology (ORL) in Germany until the beginning of the 19th century, focusing mainly on the development of scattered knowledge; the birth of the sub-specialties otology, laryngology (pharyngo-laryngology and endoscopy), and rhinology in the 19th century, combining advances in knowledge and implementation of academic structures; and the creation of the ORL specialty at the turn of the 20th century, mainly concentrating on academic organization and expansion. This period was crucial and allowed for the foundation of the German Society of Otorhinolaryngology, Head and Neck Surgery on solid ground. Germany played an important role in the development and progress of ORL internationally in the 19th century with such great contributors as Anton von Tröltsch, Hermann Schwartze, Otto Körner, Rudolf Voltolini, and Gustav Killian to mention a few.
