Benjamin Franklin (1706-90) was born in Boston. When he was twelve, his father apprenticed him to his half brother James as a printer. James was later the publisher of the New England Courant, where Franklin's first articles, "The Dogood Papers," were published before he was seventeen. He went to Philadelphia in 1723, where he was befriended by William Keith, Governor of Pennsylvania, who offered to help Franklin get started in business. They went to England, where he hoped to purchase printing equipment, but he was soon deserted by Keith and again turned to printing for a livelihood. His privately printed "A Dissertation on Liberty and Necessity, Pleasure and Pain" (1725) introduced him to leading Deists and other intellectuals in London. A year later, he returned to Philadelphia, and by 1730, he had been appointed public printer for Pennsylvania. In 1731, he established the first circulation library in the United States and, in 1743-44, the American Philosophical Society. As a publisher, his greatest success was Poor Richard's Almanack, which went through numerous editions and was translated into many languages. Over the next thirty-five years, he devoted himself largely to politics and diplomacy, by serving in the Continental Congress, signing the Declaration of Independence, and becoming Minister to France. On his return in 1785, he was elected President of the Commonwealth of Pennsylvania. Still concerned with the rights of the individual, he published papers encouraging the abolition of slavery. He died in Philadelphia. L. Jesse Lemisch is Professor Emeritus of History at the John Jay College of Criminal Justice of the City University of New York.
