The
brand name Leibniz comes from the
philosopher and
mathematician Gottfried Wilhelm Leibniz (1646–1716). The only connection between the man and the biscuit is that Leibniz was one of the more famous residents of
Hanover, where the Bahlsen company is based. At the time when the biscuit was first made there was a fashion of naming food products after historical celebrities (such as
Mozartkugeln). The
Leibniz-Keks is a plain
butter biscuit, or
Butterkeks as it is known in German, inspired by the French
Petit-Beurre created in 1886 by
Lefèvre-Utile. The word
Keks in
Leibniz-Keks was originally a corruption of the English word "
cakes" by Bahlsen (who had originally called his product "cakes" but found out that this was mispronounced by the German public). Due to the popularity of the Leibniz-Keks,
Keks has since become the generic German word for biscuit or cookies. == Design ==
