Pocket Aneroid Barometer Signed Pierre Louis Amédée Queslin (1819-1883)
Small silver-plated metal aneroid pocket barometer inscribed "ingr Queslin 1 R. de la Bourse" for Pierre Louis Amédée Queslin (1819-1883) (see below). Good overall condition, with a tiny chip on the upper rim.
Circa between 1850 and 1880.
Dimensions: Diameter 5 cm, Height 1.5 cm.
This antique pocket barometer is signed by the Parisian optical engineer Pierre Louis Amédée Queslin (1819-1883), manufacturer and merchant of scientific instruments located at 1 rue de la Bourse in Paris in the mid-19th century. In 1842, Queslin took over the optical and scientific instrument shop founded by Jean Gabriel Augustin Chevallier, one of the leading Parisian opticians of the time. The workshop, located in the immediate vicinity of the Paris Stock Exchange, offered a wide range of scientific instruments: microscopes, optical instruments, cameras for daguerreotypes, and various meteorological instruments.
From the mid-19th century, the workshop notably sold barometers using the principle of the aneroid barometer, invented in 1844 by Lucien Vidi. Unlike traditional mercury barometers, these instruments operate using a metal capsule sensitive to variations in atmospheric pressure, allowing for more compact and portable devices. These instruments bear witness to the expertise of Parisian opticians and instrument makers of the 19th century and the development of portable scientific instruments. This pocket barometer is thus a fine example of an antique scientific instrument, both a measuring tool and a testament to the history of meteorological instruments.
