The “Gründerzeit” villa, built in 1898, was purchased on August 27, 1934, by Heinrich Sonnenschein (1866–1956) and Rosa Sonnenschein (1873–1936) as a retirement residence. Heinrich had previously studied at the newly founded Leipzig Graduate School of Management (HHL), acquiring essential business fundamentals. In 1902, with a small starting capital, he acquired the machine factory for sorting cylinders and sorting machines, along with all supplies, items, and inventory for 4,930 Marks.
