Georg Heinrich David Arthur, Baron von Schickler. Baron Schickler was the banker of the Emperor of Prussia. His personal interests, however, were centred in France. Owner of the famous Ritz hotel in Paris, he was also passionate about horse racing. In pursuit of this, he purchased in 1867, the ancient Chateau Martinvast in Normandy, built by William the Conqueror, and created perhaps the most famous studs in France, one of his horses in particular, a thoroughbred Grey-le Sacy was considered to be one of the greatest racehorse of all the time.
