Yes, Jack Daniel was a real person, and a pretty fascinating one at that. From birth to death, legend surrounded him. And in between he created Jack Daniel’s Tennessee Whiskey. No one really knows exactly when Jack Daniel was born. A town fire destroyed the courthouse records, and conflicting dates on Mr. Jack's and his mother's headstones have left his date of birth in question. It’s customary to celebrate Mr. Jack’s birthday in September – so he gets a whole month. But for a man as unique as Jack Daniel, one day just wouldn’t seem proper anyway.
