He was the son of a British Navy admiral who discovered Bermuda. He attended Oxford University and studied law. At the age of 22, he heard a sermon entitled "The Sandy Foundation Shaken" and converted to the Society of Friends, or Quakers. As a result, he suffered imprisonment over three times for his faith, once imprisoned in the Tower of London for eight months. His name was William Penn, born this day, Oct. 14, 1644. King Charles II repaid a debt owed to his father by giving William Penn a land grant in America, named Pennsylvania.
