Karl Schmitz-Scholl

After his father passed, he became the owner of the company together with his older brother Wilhelm Schmitz (1861–1927). He opened several coffee stores and expanded rapidly to 560 branches in 1914. Tengelmann was named after general manager Emil Tengelmann. Tengelmann primarily sold coffee, tea, cocoa, spices, pastries and sweets. Following this product range, a second coffee roasting plant was opened in Heilbronn in 1900, followed by the Rheinische Zuckerfabrik (Rhenish Sugar Refinery) in Düsseldorf in 1906, and in 1912 the Wissoll chocolate factory started operations in Mülheim-Speldorf. From the 1920s, more coffee roasting plants and food manufacturing plants were set up, and the sales and branch network was optimized and expanded. After his death, his son Karl Schmitz-Scholl, Jr. became the sole managing director of the company, with his daughter Elizabeth Haub (née Schmitz-Scholl; 1899–1977) being a co-partner.^[3][4]

In 1895, Schmitz-Scholl married Elisabeth Franziska Josephine Maria (née Weynen; 1873–1936), having two children;

• Karl Wilhelm Erivan, Jr. (1896–1969)
• Amalie Luise "Elizabeth" (1899–1977), who married Erich Haub of Wiesbaden in 1932

They resided in Mülheim an der Ruhr.^[5]
