Science thumb|Portrait by John Riley, |alt=Oil portrait of Charles with heavy jowls, a wig of long black curls and in a suit of armour In Charles's early childhood, William Cavendish, Earl of Newcastle, was governor of the royal household and Brian Duppa, the Dean of Christ Church, Oxford, was his tutor. Neither man thought that the study of science subjects was appropriate for a future king,; and Newcastle even advised against studying any subject too seriously.; However, as Charles grew older, the surgeon William Harvey was appointed his tutor. He was famous for his work on blood circulation in the human body and already held the position of physician to Charles I; his studies were to influence Charles's own attitude to science. As the king's chief physician, Harvey accompanied Charles I to the Battle of Edgehill and, although some details are uncertain,; he had charge of Prince Charles and the Duke of York in the morning, but the two boys were back with the king for the start of battle. Later in the afternoon, with their father concerned for their safety, the two princes left the battlefield accompanied by Sir W. Howard and his pensioners.
