Today Ben Franklin would have been 303 years old. (OK technically he was born on January 6, 1706 if you use the Old Style calendar that was in place when Franklin was born)
Benjamin Franklin was born in Boston on January 17, 1706. He was the tenth son of soap maker, Josiah Franklin. Benjamin’s mother was Abiah Folger, the second wife of Josiah. In all, Josiah would father 17 children.
Josiah intended for Benjamin to enter into the clergy. However, Josiah could only afford to send his son to school for one year and clergymen needed years of schooling. But, as young Benjamin loved to read he had him apprenticed to his brother James, who was a printer. After helping James compose pamphlets and set type which was grueling work, 12-year-old Benjamin would sell their products in the streets.
