Samuel Pepys ( PEEPS; 23 February 1633 – 26 May 1703) was an English writer and Tory politician. He served as an official in the Navy Board and Member of Parliament, but is most remembered today for the diary he kept for almost a decade. Though he had no maritime experience, Pepys rose to be the Chief Secretary to the Admiralty under both Charles II and James II through patronage, diligence, and his talent for administration. His influence and reforms at the English Admiralty were important in the early professionalisation of the Royal Navy.
The detailed private diary that Pepys kept from 1660 until 1669 was first published in the 19th century and is one of the most important primary sources of the Stuart Restoration. It provides a combination of personal revelation and eyewitness accounts of great events, such as the Great Plague of London, the Second Anglo-Dutch War and the Great Fire of London.
