content: Herman von Helmholtz (1821-1894), a German scientist who worked in the fields of physics, physiology and psychology, described this type of acoustic resonator: a hollow metal body filled with air, and fitted with a small neck that could be held to his ear. The Smithsonian Institution probably purchased this set of 16 brass resonators in the mid-1860s. They were probably made by Rudolph Koenig in Paris. The original set probably had 19 resonators.
