In 1901, Eduard Schloemann OHG was founded in Düsseldorf. Just a few years later, the trading company had become a design engineering company, which initially designed control systems for hydraulic presses. As a result of its collaboration with M.A.N. from 1915 onwards, Schloemann's production portfolio was expanded to include the design and manufacture of complete hydraulic press facilities and rolling mills. The conversion to a public limited company took place in 1921.
