Aneroid Barometer

Description
Lucien Vidie was a Frenchman who made the first satisfactory metallic barometer in 1843, and obtained his first patents in 1844. For the mechanism he used a corrugated diaphragm supported by 33 helical springs encased in a strong evacuated metal box. This example is of that form, but probably not of Vidie’s manufacture. The face is marked “BARÓMETRO ANEROIDE” as well as “TEMPESTAD,” “LLÚVIA Ó VIENTO,” “VARIABLE,” “BUEN TIEMP,” and “CONSTANTE.” The scale extends from 17.5 to 31.5 inches of mercury, and from 68 to 80 cm of mercury. The Taylor Instrument Companies donated it to the Smithsonian in 1923.
