Guillaume Tirel, known as Taillevent (ca. 1310 – 1395), was an important figure in the early history of French cuisine. He was cook to the Court of France at the time of the first Valois kings and the Hundred Years' War. He wrote Le Viandier, a famous book on cookery and cookery technique, thought to be one of the first professional treatises written in France and upon which the French gastronomic tradition was founded.
