Opekta, also known as Gies & Co., was a European pectin and spice company that existed between 1928 and 1995. It is notable for its Dutch operation being based in the building at Prinsengracht 263 that would later become the Anne Frank House. Opekta started in Germany, and later expanded into the Netherlands in 1933, at which time Otto Frank moved from Germany to Amsterdam to become managing director of the new Dutch operation. Otto Frank was in charge of the manufacturing and distribution of the pectin-based gelling preparations, to be used in jam making. The company continued to trade from the same building whilst Otto Frank, his family (including his youngest daughter Anne Frank) and several other Jews hid from persecution stemming from the Nazi Occupation of the Netherlands during World War II.
The Opekta company was originally based in Cologne, Germany, being founded and owned by Austrian chemists Robert Feix and Richard Fackeldey. In 1933 the German businessman Otto Frank, then still residing in Germany, was appointed to aid their expansion into the Netherlands. Frank had already considered moving his family to the Netherlands following the election of Adolf Hitler and the rise of Nazism, so he accepted the post and moved alone to Amsterdam to find accommodation for his family and premises for the company. He had briefly managed a large rival firm, Pomosin, which traded pectin to factories from the Dutch town of Utrecht but decided that retail trade would be more lucrative in the Dutch market than wholesale. His franchise for the Amsterdam branch of Opekta was established in September 1933.
Victor Kugler, an ex-colleague from Pomosin, came on board almost immediately to help run the company. The workforce was small; apart from a junior clerk, the only other employee was a secretary, who left a few months after the company started trading. She was replaced by Miep Gies, whose duties extended from the secretarial, to public relations and advertising. In 1938, she appeared in a promotional film to promote the Opekta product, which was used to demonstrate to consumers how easy it was to use in cooking. That year they were joined by two other employees, Hermann van Pels as an herb specialist and Johannes Kleiman as a bookkeeper. Bep Voskuijl who had been the administration manager when war broke out, had been taken on the previous year, 1937.
