The story
In the 1960s, the Wilhelm Hornbach OHG was in a bad state, so his grandson Otmar Hornbach launched the idea of a do-it-yourself home improvement store after a visit to the United States. The business was filed on the stock exchange in 1987 and has expanded to a chain of 163 stores.
Otmar Hornbach died on 2 August 2014.
