George Lorimer's 'Letters from a Self-Made Merchant to His Son' is a timeless collection of Gilded Age aphorisms from a rich man - a prosperous pork-packer in Chicago to his son, Pierrepont, whom he 'affectionately' calls 'Piggy.' The writing is subtle and brilliant. Lorimer later followed this best-seller up with 'More Letters from a Self-Made Merchant.'
