On May 23, 1870, he founded G. Polysius iron foundery and engineering factory, which established itself in the then-young building materials industry with self-designed and powerful mills.

In addition to agricultural machinery, Polysius also produced grain mills, brewery and distillery equipment.

The president of ThyssenKrupp AG, Alfried Krupp von Bohlen und Halbach, was tried and convicted for the use of slave labor and crimes against humanity.

In addition, the demand for complete plants resulted in an unusually high capital commitment and entailed a variety of technological and commercial risks.

The owners of Polysius realized that the financial demands on the company would sooner or later exceed the possibilities of a family business and therefore brought in the Essen-based Fried.

In 1999, 140 years after the company was founded, it merged with the Thyssen Group to form ThyssenKrupp in what was one of Germany's first hostile takeovers.

Acquisitions strengthened Polysius in the lime kiln (Maerz AG in Zurich) and services (AC Equipment Corp., USA) sectors.

In addition, thyssenkrupp Polysius provides services along the entire life cycle of cement plants, including inspections, maintenance and the supply of innovative OEM spare parts.
