Legend has it that Marie-Antoinette introduced the croissant to France, but croissants and chocolatines are a relatively modern invention.^[3] The word croissant, which refers to a pastry shaped like a half-moon or "crescent", made its entry in the French dictionary in 1863.^[4] The type of pastry, called viennoiserie in French, was introduced in the early 19th century, when August Zang, an Austrian officer, and Ernest Schwarzer, an Austrian aristocrat, founded a Viennese bakery in Paris located at 92, rue de Richelieu.^{[citation needed]}

Croissants and pains au chocolat were originally made from a brioche base, but this was later replaced by French bakers with a bread puff pastry (pâte feuilletée levée) to become the modern product.^{[citation needed]}
