Our History

1849

On February 9, 1849, the tannery company Heintze & Freudenberg, which has 50 employees in Weinheim, is established by the partners Heinrich Christian Heintze (1800-1862) and Carl Johann Freudenberg (1819-1898).

The two entrepreneurs produce fine calf leather. The leather production plant consists of about 75 production steps, which are individually optimized in order to produce high quality leather. This quality standard is still part of Freudenberg's conception of itself.

From the beginning, there is extensive international business (including exports to the USA, Great Britain and France).
