Sir George Buck (or Buc) (c. 1560 – October 1622) was an English antiquarian, historian, scholar and author, who served as a Member of Parliament, government envoy to Queen Elizabeth I and Master of the Revels to King James I of England.
He served in the war against the Spanish Armada in 1588 and on the Cadiz expedition of 1596. He was appointed Esquire of the Body in 1588 and a Member of Parliament for Gatton, Surrey in the 1590s, also acting at times as an envoy for Queen Elizabeth. In 1603, on the accession to the throne of King James I, Buck was made a Gentleman of the Privy Chamber and knighted. In 1606, he began to license plays for publication. In 1610, he became Master of the Revels, responsible for licensing and supervising plays in Britain, including Shakespeare's later plays, and censoring them with respect to the depiction of religion and politics.
Buck's writings include a verse work, Daphnis Polystephanos: An Eclog.... (1605), an historical-pastoral poem in celebration of James I's royal ancestors. His treatise "The Third Vniversite of England" (1615) describes the educational facilities in London. His major prose work was The History of King Richard the Third, which he left in rough draft at his death. His great-nephew extensively altered it and finally published it in 1646 as his own work. Buck defended King Richard III, examining critically the accusations against him. He also discovered and introduced important new historical sources, especially the Croyland Chronicle and the Titulus Regius, which justified Richard's accession to the crown.
