In 1712,
Andrew Bradford had been the first person to start a printing business in Philadelphia. In 1723, Keimer opened a printing business near the Market-house in the city. He and Bradford were then the only printers in the colony of Pennsylvania. When Benjamin Franklin, aged 17, came to
Philadelphia looking for a job in 1723, he went first to Bradford’s printing business. Bradford had no job openings but introduced him to Keimer. Franklin found Keimer trying to set up a composition of his own, an elegy for the recently deceased poet Aquila Rose, but having difficulty. Keimer hired Franklin as his assistant, giving him his first paid job. From December 1728 to September 1729, Keimer published a weekly newspaper, which he entitled
The Universal Instructor in All Arts and Sciences: And Pennsylvania Gazette, a title Franklin would simplify to the
Pennsylvania Gazette. Along with the standard fare for an early American newspaper (news, announcements, and advertisements), Keimer included lengthy extracts from
Ephraim Chambers'
Cyclopaedia (1728) in nearly every issue. This was the first attempt to publish a general encyclopedia in the Americas, though it remained incomplete. Unfortunately for Keimer, by 1729 his business had dwindled, and he had fallen into debt. In 1729, he left for
Barbados after selling his print shop and newspaper to
Franklin. Franklin chose to discontinue the extracts from the
Cyclopaedia, which Keimer had carried on midway through the letter "A." ==Later life==
