Samuel Pepys was an English naval administrator and Member of Parliament who is now most famous for the diary he kept for a decade while still a relatively young man. Although Pepys had no maritime experience, he rose by patronage, hard work and his talent for administration, to be the Chief Secretary to the Admiralty under both King Charles II and subsequently King James II.

The detailed private diary Pepys kept is one of the most important primary sources for the English Restoration period.
