Barometers Realm

In the late 19th century, the French company Guilbert & Cie, based in Paris, specialized in the production of aneroid barometers. Their products were known for their high quality and precision, making them popular among buyers of that era. The company’s distinctive logo featured a leather belt with the initials “G&C” at the center.

The business was later taken over by Alfred Casse — better known from the partnership of Dubois & Casse — who continued the production of aneroid barometers under his own name. In 1902, the Maxant company acquired Alfred Casse’s business, carrying on the tradition of manufacturing high-quality aneroid barometers.

The Maxant logo, which includes an anchor and the initials of its founder, Leon Maxant, is a modification of the Dubois & Casse logo, indicating continuity between these companies.
