Friedrich Bezold (1842-1908) was a professor at the University of Munich who developed hearing tests with tuning forks, and worked to improved education for the hearing impaired.

This example, which consists of wood box containing nine tuning forks and two Galton whistles, was made by Max Kohl in Chemnitz.
