Manometric Apparatus, Stand

Manometric Apparatus, Stand

Usage conditions apply
In 1862, Rudolph Koenig, an acoustic instrument maker in Paris, devised a manometric apparatus in which the flame of a burning gas jet vibrates in response to the variations in pressure of a sound wave. Three years later, the Société d’Encouragement pour l’Industrie Nationale awarded him a gold medal, noting that “The most curious of all his inventions is... without doubt the one that uses gas flames as a means for revealing the vibratory movements of air.”
This stand for a manometric apparatus was probably made by Koenig, and probably purchased for the Smithsonian by Joseph Henry, the physicist who served as founding Secretary of the Institution.
