In Elberfeld, in the 1860 years, Heinrich Müller started his own business in Elberfeld as a builder. There, in the middle of the building boom of the so-called German “Gründerjahre“**, an Elberfeld bank owner* became financee and partner of the young entrepreneur. Together with him Heinrich Müller did building work of large dimensions in the following years, and thus the story of his unusual success as a selmademan in Wilhelminian Germany started.
