On the accession of Edward VI, Grafton was appointed King's Printer and this gave him the sole right to print all Acts and Statutes. In early 1553, shortly before the King's death, he published
James Peele's
The Maner and Fourme How to Kepe a Perfecte Reconyng, the earliest extant original work on bookkeeping in English. As a result, he is credited as having been responsible for the general introduction of the
double-entry bookkeeping system — originally developed in
Renaissance Italy — among English merchants. He had held the appointment of King's Printer for six years, when on the King's death, he printed a proclamation of the accession of
Lady Jane Grey, in which he signed himself "Printer to the Queen." For this he was cast into prison by
Mary I.
John Cawood became Queen's Printer, and Grafton's career as a printer ended. In prison Grafton compiled an
Abridgement of the Chronicles of England, which he published in 1563. It includes the first published English version of the verse "
Thirty Days Hath September...", although manuscript versions have been found from the 15th century. To this he added in 1568–9
A Chronicle at Large. Neither holds a high place as authorities, as they lack original material.
John Stow and Grafton had a running battle over their rival chronicles after Stow justifiably accused Grafton of copying his own work. In the
Chronicle at Large, he is the earliest writer known to refer in print to
Edward of Woodstock (Prince of Wales, Duke of Cornwall, Prince of Aquitaine) as the "Black Prince". The origins of the name remain uncertain: Grafton said he had found it in other writers, and gives no further explanation. Grafton was instrumental in the establishment and maintenance of the London hospitals. He died in 1573, probably in late April or early May, and was buried on 14 May in
Christ Church Greyfriars in London, leaving four sons and one daughter, Joan, who married the printer
Richard Tottel. Grafton's device was a tree bearing
grafts issuing from a
tun or barrel of the kind in which books were packed for transport – hence "graft-tun", an example of a
rebus. ==See also==
