Petit-Beurre

[citation needed] It was invented in 1886 by Louis Lefèvre-Utile in the city of Nantes and was inspired by some English products of the time.

The substantive Petit Beurre is a generic term from the past; it has a hyphen and when it is plural Petit-beurre is often misspelled.

It is known in Anglosphere countries as the French Petit Beurre, as "Petibör" or "Pötibör" (as called by Ülker) in Türkiye, "Πτι-Μπερ"/ "PteeBer" in Greece, and "פתיבר/Pettiber" in Israel,[citation needed] where a dairy-free version is a popular snack (the removal of dairy products allowing it to comply with Kashrut restrictions).

But Louis Lefèvre did not file the trademark "Petit Beurre LU" until April 9, 1888 to the Nantes Commercial Courts.

Another sweet butter biscuit produced in France is known as the "Petit beurre with Lorient sea salt.” In 1891, at Hanover in Germany, the Bahlsen company began making a Butterkeks (butter biscuit very similar to the French Petit Beurre) called Leibniz-Keks in homage to the philosopher and mathematician Gottfried Wilhelm von Leibniz.
