Photometer
notes: label: Description
content: Otto Schuette, an engineer in Paris, designed this small brass photometer for determining the photometric value of a gas and the optimum length of photographic exposures. The “S / BREVETÉ / S.G.D.G.” inscription on the side indicates that there was a French patent, and that the French government did not guarantee the proper functioning of the device. There was an American patent as well. This example might have been acquired for the Smithsonian by Joseph Henry, the physicist who served as founding Secretary of the Institution.
