Inked date stamps were at first called 'Bishops marks' after their inventor, Henry Bishop, Postmaster General, 1660-1663. The post office was receiving complaints about late arrival of the post. Bishop claimed: 'a stamp is invented, that is putt upon every letter shewing the day of the moneth that every letter comes to this office, so that no letter Carryer may dare to detayne a letter from post to post; which, before, was usual.' As we now know, this did not actually solve the problem, just provided more evidence that the problem existed.
