The CHEMEX® coffeemaker was invented in 1941 by the eccentric chemist Dr. Peter Schlumbohm.When designing the CHEMEX®, Schlumbohm desired to not only make brewing the perfect cup simple, but also to have the vessel be a thing of beauty. Being a chemist, he studied and understood clearly the chemistry behind the extraction of flavor and caffeine from coffee beans. The Chemex uses a specially developed double bonded filter paper that produces an extremely clean cup of coffee.
