César Ritz
In 1878, he became the manager of the Grand Hôtel National in Lucerne and held the same position, in parallel, at the Grand Hôtel in Monaco until 1888. A pioneer in the development of luxury hoteliering, he knew how to entice wealthy customers and got a reputation for good taste and elegance. He was the first to say that "the customer is never wrong". His code was "See all without looking; hear all without listening; be attentive without being servile; anticipate without being presumptuous. If a diner complains about a dish or the wine, immediately remove it and replace it, no questions asked".
