The exact date of Dr Pepper's formulation…

The exact date of Dr Pepper's formulation is unknown.

The soft drink’s creator is Brooklyn-born pharmacist Charles Alderton, who works in Morrison's Old Corner Drug Store in Waco, Texas.

To test his new drink, he had first offered it to store owner Wade Morrison, who also found it to his liking.

Patrons at Morrison's soda fountainhad soon learned of Alderton's new drink and began ordering a "Waco".

Alderton had given the formula to Morrison, who had named it Dr Pepper.

The U.S. Patent Office acknowledges December 1, 1885, as the day Dr Pepper is served for the very first time.
