Ida Kropff-Federath was the last sole owner of the Olsberg hut. Today, this is Olsberg GmbH. The roots of the company lie in the smelting of ore from the Brilon Eisenberg. In the 19th century, the smelter adapted to the changing market conditions in favor of the production of castings.
After the death of Ida Kropff-Federath on August 1, 1918, the Kropff-Federath Foundation was established. This still exists today and runs a children's home. The Kropff-Federath Gewerkenhaus is also a stop on the Gewerkenweg.
