When denied the chance to write a letter to the paper for publication, Franklin adopted the pseudonym of “Mrs. Silence Dogood”, a middle-aged widow. “Mrs. Dogood”‘s letters were published, and became a subject of conversation around town. Neither James nor the Courant’s readers were aware of the ruse, and James was unhappy with Ben when he discovered the popular correspondent was his younger brother. Franklin was an advocate of free speech from an early age. When his brother was jailed for three weeks in 1722 for publishing material unflattering to the governor, young Franklin took over the newspaper and had Mrs Dogood (quoting Cato’s Letters) proclaim: “Without freedom of thought there can be no such thing as wisdom and no such thing as public liberty without freedom of speech.” Franklin left his apprenticeship without his brother’s permission, and in so doing became a fugitive.
At age 17, Franklin ran away to Philadelphia, Pennsylvania, seeking a new start in a new city. When he first arrived, he worked in several printer shops around town, but he was not satisfied by the immediate prospects. After a few months, while working in a printing house, Franklin was convinced by Pennsylvania Governor Sir William Keith to go to London, ostensibly to acquire the equipment necessary for establishing another newspaper in Philadelphia. Finding Keith’s promises of backing a newspaper empty, Franklin worked as a typesetter in a printer’s shop in what is now the Church of St Bartholomew-the-Great in the Smithfield area of London. Following this, he returned to Philadelphia in 1726 with the help of Thomas Denham, a merchant who employed Franklin as clerk, shopkeeper, and bookkeeper in his business.
