Which London bakery created the Marie biscuit in 1874?

The London bakery that created the Marie biscuit in 1874 was Peek Freans.

Peek Freans introduced the biscuit in Bermondsey, London, to commemorate the marriage of Grand Duchess Maria Alexandrovna of Russia to the Duke of Edinburgh. Its name was derived from “Maria,” though the English form “Marie” became widely used.

The biscuit is a plain, round, lightly vanilla-flavoured wheat biscuit, usually marked with an embossed name and decorative edge. It became especially popular across Europe, including Portugal and Spain. In Spain, it is commonly called a María biscuit; in Portugal, it is closely associated with desserts such as serradura.

A common mix-up is confusing the creator with later manufacturers. Jacob’s, for example, produces a Marietta-style biscuit in Ireland, while Bakers Biscuits began making Maries in South Africa in 1898. Those are regional brands or producers, not the bakery credited with the original 1874 creation.
