Otto’s first time in Amsterdam

From 1923 to 1929, Otto and his brother Herbert and brother-in-law Erich Elias ran a bank branch in Amsterdam called M. Frank and Sons. It was located in the city centre. Due to the economic problems in Germany, many German banks opened branches in Amsterdam. As soon as the economic situation improved, many of them were closed again, including the Franks’ branch.

Johannes Kleiman was in charge of current affairs and discussed them with the management. Later, Kleiman was involved in Opekta and the founding of Pectacon.
