In the 18th century, a pastor named Benjamin Gottlob emigrated from Lower Lusatia (the German part of Poland) to Switzerland. In Geneva, his son Henri Hentsch apprenticed at Develay & Cie and was later employed by Picot, Fazy & Cie, engaged in the manufacturing of assorted fabrics, money-changing, and banking. However, after being detained in a French revolution and exiled to Nyon, Henri first began to engage in silk trading.
