Bahlsen Leibniz Kekse

Leibniz is one of Europe's most famous biscuit brands, best known for its iconic butter biscuit, the Leibniz-Keks. Named after the philosopher and mathematician Gottfried Wilhelm Leibniz, who was a famous citizen of Hanover, the brand was launched in 1891 by Hermann Bahlsen. The biscuit is famous for its '52 teeth' rectangular design, which has remained largely unchanged for over a century.

Today, the brand remains under the stewardship of the Bahlsen family, maintaining its status as a quintessential German legacy company. While the headquarters and core production remain in Hanover, Germany, the company also operates significant manufacturing facilities in Poland to serve international markets. As of 2026, Bahlsen continues to be one of the largest family-run biscuit enterprises in the world, balancing traditional recipes with modern snacking trends.
