Thomas, Isaiah, << y ZAY uh >> (1749-1831), was the leading printer and publisher in colonial America. His Boston newspaper, the Massachusetts Spy, printed strong attacks on the British government.
Thomas was born in Boston and became a printer’s apprentice there. He began to publish the Spy in 1770. In 1775, he aided Paul Revere in his famous midnight ride and fought at Lexington and Concord in the opening battles of the Revolutionary War in America.
Thomas later printed books and magazines in addition to his newspaper. He wrote a book, The History of Printing in America (1810), which still ranks as an important work on the subject.
