William Bowyer was appointed
Bailiff of
Westminster in 1560, probably with the support of
Sir Thomas Parry. In this capacity, Bowyer advised
Sir William Cecil as to the gifts expected of him in his new role of
High Steward of Westminster Abbey (1561). In 1563, probably with the good graces of Cecil, Bowyer attained the position of
Keeper of the Records in the Tower of London, although he did not receive a formal patent for the office until 18 June 1567. As Keeper, Bowyer was responsible for the vast store of government records accumulated in the Tower since the reign of
William the Conqueror. During his tenure, Bowyer created the first systematic arrangement of the records. At a cost later estimated at some £1000, Bowyer produced a six-volume overview of all the documents under his management, including "digests of the parliament, patent, charter, close, and foreign rolls, from the reigns of
King John to
Edward IV (now in the
College of Arms), as well as a list of escheats, a medieval roll of arms and a heraldic commonplace book." Bowyer sat as
Member of Parliament for
Westminster in Elizabeth's second Parliament (1563) and was named
Justice of the Peace for
Surrey in 1564. == Antiquary ==
