After Albert Loose gave up his 1905 founded " company and textile store Merkur " already in 1906 and the family left for Königsberg in September 1906, Alfred and Berta Bernheim continued the business. In December 1910, the Bernheims acquired the Merkur department store in Ludwigstraße. Around 1912, Alfred Bernheim bought the adjoining corner house at Theresienstrasse 2. In addition to the house at Ludwigstrasse 7 (four rental lots), which he owned in 1914/15, Alfred Bernheim also purchased the house at Ludwigstrasse 15 in 1916, in which the Bernheims also had a store.
