The city of Philadelphia was named for Benjamin Franklin, an American patriot and writer who became successful in the printing business after spending two years in England. His partnership with a printing house foreman, David Hall, lasted eighteen years, and they were both major figures in the city and colony. Franklin went to London to select types and meet with people he hoped would be useful to his business. In 1733, he was appointed clerk of the Pennsylvania Assembly, and he was named postmaster of Philadelphia. In 1740, Franklin was elected Postmaster of Philadelphia, and he served as Clerk of the Assembly until 1753.
