"William Pitt the Younger (28 May 1759 ? 23 January 1806) was a British politician of the late 18th and early 19th centuries. He became the youngest Prime Minister in 1783 at the age of 24. He left office in 1801, but was Prime Minister again from 1804 until his death in 1806. He was also the Chancellor of the Exchequer throughout his premiership. He is known as "the Younger" to distinguish him from his father, William Pitt the Elder, who previously served as Prime Minister of Great Britain. In 1766 he gained the style of The Honourable when his father was created an Earl."--Wikipedia.
