Samuel Loewendahl and his wife Sofie Rosalie, née Rothschild were the owners of the "Modehaus für Damenenkonfektion Geschister Loewendahl". After their death in 1914, the women's fashion house and a house at Forsterstraße 13 passed into the ownership of their children. In the course of the so-called "Aryanization", the Loewendahl siblings lost all their property. The fate of the Loewendahl siblings is commemorated today by 3 stumbling blocks in Forsterstraße 13. The commercial building at Große Ulrichstraße 2 was demolished in 1997.

The origins of the tricot factory lie in 1853 and 1860, when Leopold Levy and Simon Loewengard founded a textile factory, which initially produced only aprons. Soon after, the textile factory became a tricot weaving factory with the manufacture of underwear. The tricot weaving mill also included a tailor's shop and a bobbin winding mill. Later Hermann Levy and Carl Loewengard took over the company. The company also sold abroad to England and Holland. With a large and modern machine park, the company had up to 400 employees from Hechingen and the surrounding villages.

The brothers Moritz and Julius Ury founded the "Warenhaus Gebrüder Ury" on March 24, 1896. A comprehensive reconstruction in 1913/1914 turned the building into a magnificent six-story building with an atrium. The assortment of haberdashery, white goods and woolen goods was extensively expanded. Already in 1937 the brothers Moritz and Julius Ury were forced to leave the company. As a result of the so-called "Aryanization", in 1938 the Gebrüder Ury department store became the Textilmessehaus II with a flower store and a tax office. Moritz Ury died in exile in Switzerland in 1939.
