Guillaume Tirel, known as Taillevent, 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. His first position was enfant de cuisine to Queen Jeanne d'Évreux. From 1326 he was queux, head chef, to Philip VI. In 1347, he became squire to the Dauphin de Viennois and his queux in 1349. In 1355 he became squire to the Duke of Normandy, in 1359 his queux and in 1361 his serjeant-at-arms. The Duke of Normandy became Charles V in 1368 and Tirel continued in his service. From 1381 he was in service to Charles VI. Guillaume Tirel is generally considered one of the first truly "professional" master chefs. He died in 1395 at around 80 years of age.
He expanded a collection of recipes as 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. The book is split into three sections.
