Richard de Bury, English bishop and politician, Lord Chancellor of The United Kingdom (born 1287)

Richard de Bury, also known as Richard Aungerville or Aungervyle, was an English priest, teacher, bishop, writer, and bibliophile. He was a patron of learning and one of the first English collectors of books. He is chiefly remembered for his Philobiblon, written to inculcate in the clergy the pursuit of learning and the love of books. The Philobiblon is considered one of the earliest books to discuss librarianship in-depth. Completed shortly before de Bury's death in 1345, the book wasn't published until 1473, and this "little treatise" as he described it, has been regularly reprinted in every century following.

The Lord Chancellor, formally titled Lord High Chancellor of Great Britain, is a senior minister of the Crown within the Government of the United Kingdom. The lord chancellor is the minister of justice for England and Wales and the highest-ranking Great Officer of State in Scotland and England, nominally outranking the prime minister. The lord chancellor is appointed and dismissed by the sovereign on the advice of the prime minister. Prior to the union of England and Scotland into the Kingdom of Great Britain, there were separate lord chancellors for the Kingdom of England and the Kingdom of Scotland. Likewise, the Lordship of Ireland and its successor states maintained the office of lord chancellor of Ireland until the establishment of the Irish Free State in 1922, whereupon the office was abolished.
