His father, Josiah Franklin, was a tall

44、ow chandler who married twice, and of his seventeen children Benjamin was the youngest son. His schooling ended at ten, and at twelve he was bound apprentice to his brother James, a printer, who published the “New England Courant”. To this journal he became a contributor, and later was for a time it

45、s nominal editor. But the brothers quarreled, and Benjamin ran away, going first to New York, and thence to Philadelphia.He set up a printing house of his own from which he published “The Pennsylvania Gazette”, to which he contributed many essays, and which he made a medium for agitating a variety o

46、f local reforms. In 1732 he began to issue his famous “Poor Richard's Almanac” for the enrichment of which he borrowed or composed those pithy utterances of worldly wisdom which are the basis of a large part of his popular reputation. In 1758, the year in which he ceases writing for the Almanac,

47、 he printed in it “Father Abraham's Sermon”, now regarded as the most famous piece of literature produced in Colonial America.Meantime Franklin was concerning himself more and more with public affairs. He set forth a scheme for an Academy, which was taken up later and finally developed into the

49、money-making and politics to the end of his life. In 1748 he sold his business in order to get leisure for study, having now acquired comparative wealth; and in a few years he had made discoveries that gave him a reputation with the learned throughout Europe. In politics he proved very able both as

50、an administrator and as a controversialist,but his record as an office-holder is stained by the use he made of his position to advance his relatives. His most notable service in home politics was his reform of the postal system,but his fame as a statesman rests chiefly on his services in connection

51、with the relations of the Colonies with Great Britain, and later with France. On his arrival in Philadelphia he was chosen a member of the Continental Congress and in 1777 he was despatched to France as commissioner for the United States. Here he remained till 1785, the favorite of French society; a
