an English printer and emigrant. He was the original founder of the Pennsylvania Gazette. On October 2, 1729, Benjamin Franklin bought this newspaper. In 1712 Andrew Bradford was the first person to start a printing business in Philadelphia. In 1723 Keimer opened a printing business near the Market-house in the city. Keimer and Bradford were then the only printers in the colony of Pennsylvania. Keimer had come to America with an old printing press, and a worn-out font of English letters. In later years Keimer's business dwindled. He decided to sell his print shop business and go to Barbados. There in 1731, at Bridgetown, he published the Barbadoes Gazette.
