Daye, Stephen (1594?-1668), with his son Matthew, set up and operated the first printing office in what is now the United States. In 1638, the Dayes sailed from England to Cambridge, Massachusetts, with Joseph Glover, a British clergyman. Glover brought along a press, type, and paper. Glover died on the voyage, but the Dayes and Glover's widow set up the press in America. The first publication of the press was the "Freeman's Oath" (1639). No copy of this is known to survive. In 1640, the Dayes printed the Bay Psalm Book. Eleven copies of that book still exist. See Bay Psalm Book.
