PHBN COMPANY HISTORY

The company which started operations in Paris in 1859 by the founders, Messrs. Pertuis, Hulot, Bourgeois and Naudet,  whose first names are unknown  began operating as Naudet & Cie in 1860. Their Trade Mark was "PNHB," for their last names, and later was said to mean, Paul Naudet Holosteric Barometer. They were located at 4, Place Thorigny, Paris. Over the years various changes took place in ownership and management, but the high quality of their instruments was maintained. They survived the rigors of WW II. In 1985, the company's headquarters moved to 12, rue du Bois, in Le Perreux sur Marne.   

The firm of Naudet, Pertuis & Hulot began to manufacture high quality aneroid barometers and barographs in Paris in 1860, and is still in business today as Naudet. The workshops have been located in Perreux-sur-Marne since 1965.

The company’s trademark is the cipher “PNHB”, formed of the initials of the surnames of the company’s founders, Pertuis, Naudet and Hulot, and ‘Baromètres.’ Paul Naudet was France’s premier barometer maker of the second half of the 19th century.  The company gave its aneroid products the unique label ‘holosteric’ barometers and, over the years, PNHB also came to represent ‘Paul Naudet Baromètres Holostérique.’

It is a well preserved meteorological instrument in good cosmetic and working condition.

The material is Brass with a few discolorations / scratches (see the uploaded photos that are part
