Adam Politzer, otology and the Centennial Exhibition of 1876. 1975

S E Stool, and M J Kemper, and B Kemper

The Centennial Exhibition of 1876 was held in Philadelphia. Among the exhibits was a collection of temporal bone dissections produced by Adam Politzer of Vienna. This exhibit included both normal and pathological temporal bones, and emphasized the relationship of the tympanic membrane to the middle ear, external canal and bony labyrinth. At the close of the Centennial Exhibition the collection was purchased by the College of Physicians of Philadelphia. This collection and the congress associated with the Centennial had a tangible effect on the otology in this country.
