William Camden (2 May 1551 – 9 November 1623) was an English antiquarian, historian, topographer, and officer of arms. He wrote the first chorographical survey of the islands of Great Britain and Ireland and the first detailed historical account of the reign of Elizabeth I of England.
Camden was born in London. His father, Sampson Camden, was a member of The Worshipful Company of Painter-Stainers. He attended Christ's Hospital and St Paul's School, and in 1566 entered Oxford (Magdalen College, Broadgates Hall, and finally Christ Church). At Christ Church, he became acquainted with Philip Sidney, who encouraged Camden's antiquarian interests. He returned to London in 1571 without a degree. In 1575, he became Usher of Westminster School, a position that gave him the freedom to travel and pursue his antiquarian researches during school vacations.
In 1577, with the encouragement of Abraham Ortelius, Camden began his great work Britannia, a topographical and historical survey of all of Great Britain and Ireland. His stated intention was "to restore antiquity to Britaine, and Britaine to its antiquity." The first edition was published in 1586. The work, which was written in Latin, was very popular, going into seven editions by 1607, each considerably enlarged from its predecessor. The 1607 edition included for the first time a full set of English county maps, based on the surveys of Christopher Saxton and John Norden, and engraved by William Kip and William Hole (who also engraved the fine title page). The first English language edition, again expanded, translated by Philemon Holland (probably in collaboration with Camden), appeared in 1610.
