Isaiah Thomas (January 8, 1749 - April 4, 1831), was an American newspaper publisher and author. He performed the first public reading of the Declaration of Independence in Worcester, Massachusetts and reported the first account of the Battles of Lexington and Concord. He was the founder of the American Antiquarian Society.
Thomas was born in Boston, Massachusetts. He was apprenticed on July 7, 1756 to Zechariah Fowle, a Boston printer, with whom, after working as a printer in Halifax, Portsmouth, New Hampshire, and Charleston, South Carolina, he formed a partnership in 1770.
In Boston, in 1774, Thomas published the Royal American Magazine, which was continued for a short time by Joseph Greenleaf, and which contained many engravings by Paul Revere.
