A:  Dr. Pepper!

Charles Alderton, a young pharmacist working at Morrison’s store, is believed to be the inventor of the now famous drink. Alderton spent most of his time mixing up medicine for the people of Waco, but in his spare time he liked to serve carbonated drinks at the soda fountain. He liked the way the drug store smelled, with all of the fruit syrup flavor smells mixing together in the air. He decided to create a drink that tasted like that smell. He kept a journal, and after numerous experiments he finally hit upon a mixture of fruit syrups that he liked.

And yes, there’s a Dr. Pepper Museum!
