Company founded by ERNST HINRICHS in Osterode. The first dental impression and model plasters are developed with dentist Dr. Kühns. The positive response to these world-first dental plasters enables the purchase of the company premises in Osterode on the Gipsmühlenweg.
Dr Kühns’ impression plaster is especially successful, and also the newly developed model plasters
with reduced expansion and exact setting time.
